were you sprayed by the Extinction Rebellion's fake blood?

The Extinction Rebellion activists then opened up a fire hose and sprayed fake blood, which they had made from beet juice, onto the building. But they immediately lost control of the hose and ended up drenching the sidewalks and least one bystander.
It has reached the point where many, including myself, are reluctant to speak out. Who wants to be labelled a climate change denier = right winger = doesn't listen to the science, etc. etc.?

Ten years ago I read The Climate Fix by Roger Pielke jr which confirmed my belief that we were being told less than half the truth.

More recently, when people said to me things like, "Even after the (Australian) bushfires, Scott Morrison doesn't believe in climate change". The next sentence, "How dumb is that?" didn't even have to be said. I held my tongue. The Earth is not flat.

Hence, it's important that you follow this link, read the reviews and then read this book: Apocalypse Never: Why Environmental Alarmism Hurts Us All by Michael Shellenberger

extreme weather and inconvenient truths

Inconvenient truth 1: There is no convincing evidence of a link between extreme weather and climate change.

Inconvenient truth 2: Well researched scientists (eg. Roger Pielke jnr, Judith Curry) who argue for Inconvenient truth 1 will be falsely, maliciously and relentlessly accused of being climate change deniers, in the pay of energy companies etc.

don't believe in science

Best to read the whole thing: Why I Don’t “Believe” in “Science” by Robert Tracinski. I'll quote one section below:
The problem is the word “belief.” Science isn’t about “belief.” It’s about facts, evidence, theories, experiments. You don’t say, “I believe in thermodynamics.” You understand its laws and the evidence for them, or you don’t. “Belief” doesn’t really enter into it.

So as a proper formulation, saying “I understand science” would be a start. “I understand the science on this issue” would be better. That implies that you have engaged in a first-hand study of the specific scientific questions involved in, say, global warming, which would give you the basis to support a conclusion. If you don’t understand the basis for your conclusion and instead have to accept it as a “belief,” then you don’t really know it, and you certainly are in no position to lecture others about how they must believe it, too.

Because science is about evidence, this also means that it carries no “authority.” The motto of the Royal Society is nullius in verba—”on no one’s word”—which is intended to capture the “determination of Fellows to withstand the domination of authority and to verify all statements by an appeal to facts determined by experiment.”

That’s the opposite of what “I believe in science” is intended to convey. “I believe in science” is meant to use the reputation of “science” in general to give authority to one specific scientific claim in particular, shielding it from questioning or skepticism.

“I believe in science” is almost always invoked these days in support of one particular scientific claim: catastrophic anthropogenic global warming. And in support of one particular political solution: massive government regulations to limit or ban fossil fuels.

But these two positions involve a complex series of separate scientific claims—that global temperatures are rising, that humans are primarily responsible, that the results are going to be catastrophic for human life, that rising temperatures can be halted—combined with a series of economic and political propositions. For example: that action to ban fossil fuels would be more efficacious than using the wealth made possibly by fossil fuels to help humans adapt to future climatic changes.

The purpose of the trope is to bypass any meaningful discussion of these separate questions, rolling them all into one package deal–and one political party ticket.

The trick is to make it look as though disagreement on any of these specific questions is equivalent to a rejection of the scientific method and the scientific worldview itself.

Judith Curry on the current state of climate science

Judith Curry STATEMENT TO THE COMMITTEE ON SCIENCE, SPACE AND TECHNOLOGY OF THE UNITED STATES HOUSE OF REPRESENTATIVES
Hearing on Climate Science: Assumptions, Policy Implications and the Scientific Method
29 March 2017

14pp pdf, quite inspirational IMO, read the whole thing

Science is an iterative process of multi hypothesis formation, collecting data and testing that data against the variety of hypotheses

Beware of dogmatic claims (alarmists, deniers), be sensitive to the uncertainty and complexity of the climate science issue

Explanation of the how and why we have got to a bad place in climate science (page 11, extract below)

There is a war on science - not from Trump but from within the science establishment itself (page 12, extract below)
How and why did we land between a rock and a hard place on the issue of climate science?

There are probably many contributing reasons, but the most fundamental and profound reason is arguably that both the problem and solution were vastly oversimplified back in the early 1990’s by the UNFCCC, who framed both the problem and the solution as irreducibly global in terms of human-caused global warming. This framing was locked in by a self-reinforcing consensus-seeking approach to the science and a ‘speaking consensus to power’ approach for decision making that pointed to a single course of policy action – radical emissions reductions.

The climate community has worked for more than two decades to establish a scientific consensus on human-caused climate change, prematurely elevating a hypothesis to a ruling theory. The IPCC’s consensus-seeking process and its links to the UNFCCC emissions reduction policies have had the unintended consequence of hyper-politicizing the science and introducing bias into both the science and related decision making processes. The result of this simplified framing of a wicked problem is that we lack the kinds of information to more broadly understand climate variability and societal vulnerabilities. The politicization of climate science has contaminated academic climate research and the institutions that support climate research, so that individual scientists and institutions have become activists and advocates for emissions reductions policies. Scientists with a perspective that is not consistent with the consensus are at best marginalized (difficult to obtain funding and get papers published by ‘gatekeeping’ journal editors) or at worst ostracized by labels of ‘denier’ or ‘heretic.’

Policymakers bear the responsibility of the mandate that they give to panels of scientific experts. In the case of climate change, the UNFCCC demanded of the IPCC too much precision where complexity, chaos, disagreement and the level current understanding resists such precision. Asking scientists to provide simple policy-ready answers for complex matters results in an impossible situation for scientists and misleading outcomes for policy makers. Unless policy makers want experts to confirm their preconceived bias, then expert panels should handle controversies and uncertainties by assessing what we know, what we don’t know, and where the major uncertainties lie....
War on Science
With the advent of the Trump administration, concerns about ‘war on science’ have become elevated, with a planned March for Science on 22 April 2017. Why are scientists marching? The scientists’ big concern is ‘silencing of facts’. This concern apparently derives from their desire to have their negotiated ‘facts’ – such as the IPCC consensus on climate change – dictate public policy. These scientists also fear funding cuts and challenges to the academic scientific community and the elite institutions that support it.

The ‘war on science’ that I am most concerned about is the war from within science – scientists and the organizations that support science who are playing power politics with their expertise and passing off their naïve notions of risk and political opinions as science. When the IPCC consensus is challenged or the authority of climate science in determining energy policy is questioned, these activist scientists and organizations call the questioners ‘deniers’ and claim ‘war on science.’ These activist scientists seem less concerned with the integrity of the scientific process than they are about their privileged position and influence in the public debate about climate and energy policy. They do not argue or debate the science – rather, they denigrate scientists who disagree with them. These activist scientists and organizations are perverting the political process and attempting to inoculate climate science from scrutiny – this is the real war on science.

Climate change: R&D breakthrough, at last

Any real progress on de carbonisation of the energy economy has been stuck for some years by the economics of renewables. They are more expense than fossil fuels and so the developing world in particular can't afford to go down that path. See the graph which shows that the CO2 emissions of China and India in particular have increased dramatically in the past 20 years.


In Australia we have the Green Party and the Labour Party who are in denial about the high cost of renewables. The Greens have called for a 90 per cent renewable energy target by 2030 (source). Labour has called for a carbon reduc­tion target of 45 per cent by 2030 (source). Greenpeace activists demand 100% renewables.

The problem with these policies is that they imply that renewables in their current state of development can do the job. From my reading of the evidence of those who have studied this in detail, they can't.

Let's assume for a minute that there are people who are neither alarmists, nor deniers, that there are people who actually want to think more deeply about these issues than the latest media headline about the Paris summit or how it's going to be very hot this summer. For those people here are some articles which provide a starting point:
Has Renewable Energy Finally Ended the Great Clean Energy Stagnation? by Jesse Jenkins
A Look at Wind and Solar Part 1: How Far We've Come by Alex Trembath
A Look at Wind and Solar Part 2: Is There An Upper Limit To Intermittent Renewables? by Alex Trembath

Nevertheless, it seems that something quite significant has at least coincided with the 2015 United Nations Climate Change Conference in Paris. It follows that if de-carbonisation of the energy supply is a good thing and that renewables or nuclear for that matter can't currently replace fossil fuels (due to cost in the case of nuclear) then what is required is more research and development in order to lower the price of these alternatives.

From this perspective the dual announcement of the government based Mission Initiative and the entrepreneurial based Breakthrough Energy Coalition which focus on the need for more R&D is a very good thing.

Bill Gates has been pushing for more R&D for a while, see American Innovation Energy Council and TerraPower. I guess more wealthy people are coming on board now and even Obama, from the government perspective, now sees the need for more R&D.

Under capitalism the benefits of more R&D tend to go to all capitalists since once a breakthrough is made it is hard to stop competitors finding a way to copy it. In cases of energy development with long time lines and massive expenditure requirements it can only happen this way with big government - big capitalists seeing the need and combining efforts. Historically, massive R&D has happened before due to huge rivalry between different big powers. One example, was the Manhattan Project when America feared that the Nazis would develop the first nuclear weapon. Another example was the crisis caused by the USSR putting the Sputnik into space. This quickly led to funding for massive science research in the USA which created the moon landings, the internet, etc. I guess an issue has to be perceived as urgent before that happens. So my guess is that this dual announcement does represent a significant change.

Could this be the beginning of the end of a futile argument between global warming alarmists and deniers that has distorted our political landscape for the last 20 years?

Renewable energy costs more than fossil fuels

This is the beginning of a long thread (actually, a couple of long threads) from the Making Sense of Climate Denial Course ("Climate change is real, so why the controversy and debate? Learn to make sense of the science and to respond to climate change denial"), which ran from April-June, 2015.

If you want to read the full thread which contains this introduction then go here straight away. Otherwise, keep reading here if you first want the introduction which sparked the thread before deciding whether or not to read the whole thing.

It represents a challenge to the course organisers on the issue of whether renewables are more expensive than fossil fuels.

Fact: Renewable energy costs more than fossil fuels
discussion posted 4 days ago by ArthurD
Vote for this post, there are currently 3 votes 3 Votes

This simple fact is common ground among all serious participants in debates concerning what to do about global warming.

It is the central reason why many argue for a carbon tax and subsidies to renewables. Without such measures there is no hope of renewables replacing fossil fuels.

It is also the central reason for concern that the world will continue on the present "business as usual" track towards significant problems from global warming before the end of the century. No such measures are in fact being taken to the extent that would be required to make a significant difference.

The vast majority of emissions are expected to come from poor countries like India and China rapidly industrializing over the next few decades.

They are not cannot and will not be switching from fossil fuels to renewables because they cannot afford the extra cost. Consequently 4 times as much additional energy is being supplied by coal each year as by renewables.

There are NO serious claims that renewables will become cheaper than fossil fuels. What IS being claimed is that they will become cheaper than they are now but that it is still NECESSARY to make fossil fuels more expensive through such measures as carbon taxes in order to internalize the external costs imposed by emissions.

Numerous posts with "good news" about trends towards renewables demonstrate that many students in this course are unaware of these facts.

Worse, course staff are actively in denial about them.

I started a thread on this, which had 47 posts --> this course helps preserve fossil fuels

Another student posted several links as follows:
"I'm a serious student of the economic debate, with a degree in economics and in science: renewables demonstrably cost less than consumables, and I nor the World Bank, nor http://thesolutionsproject.org/ nor https://www.irena.org/DocumentDownloads/Publications/Renewable_Power_Generation_Costs.pdf nor Swanson's Law nor http://www.skepticalscience.com/renewable-energy-is-too-expensive.htm nor the IEA do not tacitly or otherwise agree to the myth of cheap consumables; it's a bald misrepresentation to suggest consumables are cheaper."
Not one of these links claims that renewables are or will become cheaper than fossil fuels so that poor countries could switch to them while industrializing. The last, from the group behind this course, repeats what is in fact usually claimed:
"When you account for the effects which are not reflected in the market price of fossil fuels, like air pollution and health impacts, the true cost of coal and other fossil fuels is higher than the cost of most renewable energy technologies."
This is true but completely irrelevant to the question of whether renewables will or can replace fossil fuels in the poor countries that are industrializing.

They are paying ACTUAL costs in the ACTUAL situation of no "carbon price" and people on $2 per day have much higher priorities. They do NOT "account for the effects". (Neither for that matter do most developed countries that could afford to, but the point is that even if they did, poor countries still CANNOT do so while industrializing).

The response of course staff was to close down the thread before I could even point out that NONE of the links offered even denied, let alone refuted the commonly accepted basis for all serious debate that renewables are not replacing fossil fuels because their actual costs are greater.

Please take a look at the closed thread and then come back here and follow this thread if you are interested in serious discussion of what can be done about the ACTUAL situation rather than pretense that endlessly repeating what OUGHT to be can change what is continuing to happen - "business as usual" with rapidly growing emissions.

For the subsequent (lengthy) discussion of these introductory comments go here

Turn down the hype

Guest post by Arthur Dent:

According to the World Bank:
“By acting now, acting together and acting differently, we will be able to transition to a low emissions, climate resilient development path and hold warming below 2°C.”(1)
To help achieve this, a MOOC sponsored by the World Bank (Turn Down the Heat) requires students to produce “digital artefacts” with the aim “create a sense of urgency and a call to action for individuals, companies or countries to change behaviors associated with a warming planet”.

My call is for the World Bank to change its behaviour and “turn down the hype”.

It should be obvious that none of the measures advocated by the World Bank have had much impact on the planet warming, and there is no reason to expect that creating a sense of urgency in support of more of the same will have a better result.

The IPCC's authoritative report on Mitigation of Climate Change(2) shows clearly that there is no realistic prospect of holding warming below 2°C.

The simple reality is that most emissions will result from the rapid industrialization of developing countries like India and China who cannot and will not switch from the cheapest energy sources available while they remain poor. No amount of hype will change that reality.

If the problem was as grave and urgent as claimed there would be no alternative but for developed nations who can afford the cost to switch from cheaper fossil fuels to more expensive nuclear power and also pay the costs of the entire world doing the same. But the World Bank does not advocate that, so it is difficult to believe it takes its own hype seriously.

Wind and solar power cannot solve the problem because they are intermittant. Power is also needed when the wind is not blowing and the sun is not shining. There is no technology on the horizon that could store energy cheaply enough to compete with the dispatchable power from fossil fuels, even if wind and solar power was free. Instead of pretending that wind and solar could do the job it is clearly necessary to act differently. Since there is no viable replacement for fossil fuels on the horizon that developing countries could afford, it is necessary to do something very different from what the World Bank advocates.

We will need some breakthroughs in fundamental technology. Neither the regulatory nor the market pricing mechanisms advocated by the World Bank can achieve that. Massive investments in research and development and fundamental science are required. Contrary to the hype there is no “return” on that investment. As with all fundamental science, the results have to be made freely available to the countries that are too poor to pay for it. So the “free rider” problem ensures that no carbon pricing mechanism could motivate such investment. At present each developed country is hoping that somebody else will pay to develop the necessary technology. There is no “national” benefit in doing so. It is a global, not a national problem. The most ambitious national targets for R&D are about 3% of GDP for all purposes. These targets are not being met, despite the fact that new technology is the driving force for economic growth.

A global levy on developed countries that can afford it is required, to pay for the costs of a massive global R&D program that is not expected to produce any “return” on the investment, other than “merely” solving the problem of global warming.

That may require a significant expansion in the total scientific workforce and consequently a long lead time for education.

If it is not successful, then we will have to resort to some combination of geo-engineering, adaptation strategies and subsidizing nuclear power in all countries, at potentially vastly greater costs. But even if a massive global R&D program failed to produce clean energy competitive with fossil fuels, it would at least accelerate economic growth generally and enable the whole world to afford more expensive energy than fossil fuels more quickly.
“Modernization has liberated ever more people from lives of poverty and hard agricultural labor, women from chattel status, children and ethnic minorities from oppression, and societies from capricious and arbitrary governance. Greater resource productivity associated with modern socio-technological systems has allowed human societies to meet human needs with fewer resource inputs and less impact on the environment. More-productive economies are wealthier economies, capable of better meeting human needs while committing more of their economic surplus to non-economic amenities, including better human health, greater human freedom and opportunity, arts, culture, and the conservation of nature.”(3)
We need more modern technology, not medieval windmills.

the ecomodernist manifesto

ecomodernist manifesto

I'm trying to work out why ideas like this have so little traction in any significant political party. Liberals, Labour and Green are all hopeless. I've summarised some of the key points below but it would be better to read the whole thing.

1) We live in the Anthropocene, the Age of Humans

2) There are no good reasons for pessimism.

3)... we affirm one long-standing environmental ideal, that humanity must shrink its impacts on the environment to make more room for nature, while we reject another, that human societies must harmonize with nature to avoid economic and ecological collapse

4) There is an answer to environment concerns that are heard every day. The answer is to decouple intensive human development from environmental issues.

5) in contradiction to the often-expressed fear of infinite growth colliding with a finite planet, demand for many material goods may be saturating as societies grow wealthier. Meat consumption, for instance, has peaked in many wealthy nations and has shifted away from beef toward protein sources that are less land intensive (other issues of concern outlined too)

6) Ecosystems around the world are threatened today because people over-rely on them ... Conversely, modern technologies, by using natural ecosystem flows and services more efficiently, offer a real chance of reducing the totality of human impacts on the biosphere

7) Plentiful access to modern energy is an essential prerequisite for human development

8) The energy sources we need are cheap, clean, dense, and abundant. Candidates include next-generation solar, advanced nuclear fission, and nuclear fusion

9) Our Environmental future is a human spiritual or aesthetic choice more than a material or utilitarian choice ... the decoupling makes this choice possible

10) Don't confuse modernity (good) with capitalism (questionable)
"Too often, modernization is conflated, both by its defenders and critics, with capitalism, corporate power, and laissez-faire economic policies. We reject such reductions. What we refer to when we speak of modernization is the long-term evolution of social, economic, political, and technological arrangements in human societies toward vastly improved material well-being, public health, resource productivity, economic integration, shared infrastructure, and personal freedom.

Modernization has liberated ever more people from lives of poverty and hard agricultural labor, women from chattel status, children and ethnic minorities from oppression, and societies from capricious and arbitrary governance. Greater resource productivity associated with modern socio-technological systems has allowed human societies to meet human needs with fewer resource inputs and less impact on the environment. More-productive economies are wealthier economies, capable of better meeting human needs while committing more of their economic surplus to non-economic amenities, including better human health, greater human freedom and opportunity, arts, culture, and the conservation of nature.

Modernizing processes are far from complete, even in advanced developed economies ..."

Judith Curry's evaluation of the climate change debate

Judith Curry's testimony to The House of Representatives Committee on Science, Space and Technology Full Committee Hearing about The President’s UN Climate Pledge: Scientifically Justified or a New Tax on Americans?

Here is the [link] for the hearing, which includes link to all of the testimonies and also the webcast

Judith Curry (blog):
The central issue in the scientific debate on climate change is the extent to which the recent (and future) warming is caused by human-caused greenhouse gas emissions versus natural climate variability that are caused by variations from the sun, volcanic eruptions, and large-scale ocean circulations.

Recent data and research supports the importance of natural climate variability and calls into question the conclusion that humans are the dominant cause of recent climate change. This includes:
  • The slow down in global warming since 1998 
  • Reduced estimates of the sensitivity of climate to carbon dioxide 
  • Climate models that are predicting much more warming than has been observed so far in the 21st century
While there are substantial uncertainties in our understanding of climate change, it is clear that humans are influencing climate in the direction of warming. However this simple truth is essentially meaningless in itself in terms of alarm, and does not mandate a particular policy response.

We have made some questionable choices in defining the problem of climate change and its solution:
  • The definition of ‘dangerous’ climate change is ambiguous, and hypothesized catastrophic tipping points are regarded as very or extremely unlikely in the 21st century
  • Efforts to link dangerous impacts of extreme weather events to human-caused warming are misleading and unsupported by evidence.
  • Climate change is a ‘wicked problem’ and ill-suited to a ‘command and control’ solution
  • It has been estimated that the U.S. national commitments to the UN to reduce emissions by 28% will prevent three hundredths of a degree centigrade in warming by 2100.
The inadequacies of current policies based on emissions reduction are leaving the real societal consequences of climate change and extreme weather events largely unaddressed, whether caused by humans or natural variability.

The wickedness of the climate change problem provides much scope for disagreement among reasonable and intelligent people. Effectively responding to the possible threats from a warmer climate is made very difficult by the deep uncertainties surrounding the risks both from the problem and the proposed solutions.

The articulation of a preferred policy option in the early 1990’s by the United Nations has marginalized research on broader issues surrounding climate variability and change and has stifled the development of a broader range of policy options.

We need to push the reset button in our deliberations about how we should respond to climate change:
  • We should expand the frameworks for thinking about climate policy and provide a wider choice of options in addressing the risks from climate change. 
  • As an example of alternative options, pragmatic solutions have been proposed based on efforts to accelerate energy innovation, build resilience to extreme weather, and pursue no regrets pollution reduction 
  • Each of these measures has justifications independent of their benefits for climate mitigation and adaptation. 
  • Robust policy options that can be justified by associated policy reasons whether or not human caused climate change is dangerous avoids the hubris of pretending to know what will happen with the 21st century climate.
This concludes my testimony.
Judith also recommends reading the testimonies of Harbert and Thorning

a new inconvenient truth

President Obama is wrong when he links climate change to extreme weather events.

Roger Pielke jnr gave expert testimony to the US Senate that hurricanes have declined by 20% since 1900

In response a Democrat senator, Raul Grijalva, has launched an investigation into him as a paid dupe of the oil and gas companies.

Pielke's new book, The Rightful Place of Science: Disasters and Climate Change documents the evidence.

The witch hunt against Pielke jnr is documented here

Pielke points out that Democrats are just as irrational as Republicans, that the narrative that Republicans are the main source of nutty ideas is exposed

Extract from a review of Piele jnrs new book:
... Pielke published a piece about climate change and natural disasters on the then-new website of statistician Nate Silver. The gist of the piece was that the rising cost of natural disasters (such as hurricanes) was the result not of an increase in the severity of those events, but of an increase in wealth: “We’re seeing ever-larger losses simply because we have more to lose—when an earthquake or flood occurs, more stuff gets damaged.” Based on that mild-mannered thesis, Slate branded Pielke a “climate-change denialist,” Daily Kos characterized him as a “climate disinformer,” and New York Times columnist Paul Krugman called him a “known irresponsible skeptic.”

In making his point about politicians telling stretchers about the weather, Pielke points to a 2013 speech by Obama in which the president said, “In a world that’s getting warmer than it used to be, all weather events are affected by it—more extreme droughts, floods, wildfires, and hurricanes.”

environmental talking points and references

This is an appeal for myself and others to study more rigorously the real state of the world, ie. the environmental world and its connections to the political, ethical, philosophical and economic worlds. My study is incomplete but I feel I have done enough to make some valid points and to map out a path of further study. At the least, this article is an annotated reading list which indicates the general direction of my thinking at this stage.

It is difficult to separate your hopes and world view (we all carry around and rely on bullshit detectors, filters and blinkers) from an objective assessment of what is really happening in the world.

At one extreme there is a world view which I will call "deep Green" that we are rushing towards environmental Armageddon. At the other extreme you find cheery technological optimism, that any problems created by our technological advance can also be solved by further technological progress.

In history we find people who have made extreme predictions and have ended up looking foolish. See The Bet: Paul Ehrlich, Julian Simon and Our Gamble over Earth's Future
"University of Illinois economist Julian Simon challenged Stanford biologist Paul Ehrlich to put his money where his mouth was and wager up to $1,000 on whether the prices of five different metals would rise or fall over the next decade. Ehrlich and Simon saw the price of metals as a proxy for whether the world was hurtling toward apocalyptic scarcity (Ehrlich’s position) or was on the verge of creating greater abundance (Simon’s).

Ehrlich was the country’s, and perhaps the world’s, most prominent environmental Cassandra. He argued in books, articles, lectures, and popular television programs that a worldwide population explosion threatened humanity with “the most colossal catastrophe in history” and would result in hundreds of millions of deaths from starvation and dire shortages not just of food but all types of raw materials.

Simon, who passed away in 1998, was a population optimist. A disciple of conservative University of Chicago economist Milton Friedman, Simon believed the doomsayers’ models gave little or no credit to the power of efficient markets and innovative minds for developing substitutes for scarce resources and managing out of crises. He went so far as to claim that population growth should “thrill rather than frighten us.”
http://www.gatesnotes.com/Books/The-Bet
Although Paul Ehrlich's extreme predictions were wrong and the bet was won by Julian Simon it does not follow logically that there may be extreme environmental concerns that we should be dealing with urgently. I think the only valid response to those ringing alarm bells about environmental issues is to investigate deeply the real state of the world. This is a different response to ridiculing alarmists who have been wrong in the past.

Humans are contrasted to nature by the deep Green side of the discussion. I feel that the humans - nature division is a false dichotomy which leads to a contamination of language. Words such as wilderness, sustainability, biodiversity and ecology need to be looked at carefully.

Wilderness is a human social, religious construct. This is powerfully argued from within the environmental movement by William Cronon in The Trouble with Wilderness. The concept of wilderness tends to reinforce a polarised human-nature dichotomy with nature worship on one side and arrogant human "mastery" of nature on the other.

Biodiversity appears to be a plural concept, a pseudo scientific term, partly invented for environ-political reasons, which can't be clearly defined (see James MacLaurin and Kim Sterelny's What is Biodiversity?). No doubt, biodiversity is a "good thing" but there isn't just one biodiversity but a plurality.

Is ecology a science, or, what sort of science is ecology? Mark Sagoff suggests that it isn't a science (What Does Environmental Protection Protect?), that holistic systems ecology is a figment of the environmental imagination, that ecological concepts such as structure, function, stability, resilience (emergent holistic properties) are more or less meaningless terms. In his vision the whole debate about invasive species is a distraction since species migrating is a natural process anyway. However, I lean to those who seem to be more expert on this issue such as Daniel Simberloff, who specifically reject Mark Sagoff's views and who appear to have studied the issue more closely:
"Sagoff [Journal of Agricultural and Environmental Ethics 18 (2005), 215–236] argues, against growing empirical evidence, that major environmental impacts of non-native species are unproven. However, many such impacts, including extinctions of both island and continental species, have both been demonstrated and judged by the public to be harmful"
A better descriptor of where we are at is co-evolution in the Anthropocene.
"The Anthropocene is an informal geologic chronological term that marks the evidence and extent of human activities that have had a significant global impact on the Earth's ecosystems" (Wikipedia).
This recognises that we are both part of nature, an evolutionary product, as well as recognising our unique influence over nature, both good and bad.

How can this issue be better framed? Humans who are a part of nature, a tool making product of natural evolution, are destroying huge amounts of the rest of nature and this is bad in its own right (in a spiritual or aesthetic sense) as well as incredibly dangerous for human quality of life too (anthropogenic global warming and other issues - ocean acidification, stratospheric ozone depletion, nitrogen cycle, phosphorous cycle, global freshwater use, change in land use, biodiversity loss, atmospheric aerosol loading and chemical pollution). The claim is that we are shitting in our own nest and that is aesthetically ugly and dangerous for our own health.

"Tread lightly on the Earth". This is an ascetic and / or anti consumerist position. eg. Mahatma Gandhi. Poverty ennobles and wealth corrupts. But it turns out that in India Mahatma Gandhi is highly respected for his nationalistic, non violent and humanistic outlooks but less respected for his ascetic, deprivation and traditional viewpoints, that the caste system is natural, akin to an ecological niche. Once again, the modernist beliefs in equality undermines the position of letting things stay as they are. See Shome, Siddhartha's The New India versus the Global Green Brahmins.

But anti-consumerism, for those who are currently advantaged, can be argued from a non Gandhi position as well. See the Vaclav Smil references below.

Pascal Bruckner has written a philosophical critique and addressed the House of Lords about the promotion of fear and mother earth as a sacred object by deep Green ideology. I would see this as an important contribution to human political psychology but one which does not claim to begin to investigate the real state of the physical world.

There is no static balance in nature. Irreversible change has always been the real state of the natural world. See Alston Chase's In a Dark Wood: The Fight over Forests and the Myths of Nature where he critiques the biocentric viewpoints that "There is a balance of nature", 'that nature can be "healthy' or "unhealthy" ' in a similar sense to the human body being healthy or unhealthy, that "in the beginning all was perfect" (a Garden of Eden or Golden Age) and that "Nature is sacred".

Rambunctious Garden is a good metaphor for an environmental future. Not the only metaphor but a good metaphor. This is the title of a book by Emma Marris. Subtitle: Saving Nature in a Post Wild World. She is saying that nurturing nature in the big cities is an important part of the path we go down. It fits my preferred vision of human-nature co evolution in the Anthropocene. However, it does seem to be written more from the point of view of how to think about nature rather than an attempt to assess the real state of the world:
Every single chapter challenged my thinking about how we classify and define what is natural, what’s worth saving, why, and how to got about it. However, I must admit, I began reading with the expectation of spending some time communing with, well, nature. But this book dwells less on experiential factors and more on the meta: it dives deeply into the thinking and philosophical frameworks that undergird the conservation of nature today. http://sciencetrio.wordpress.com/2013/07/12/review-rambunctious-garden-saving-nature-in-a-post-wild-world-by-emma-marris/
Anthropogenic global warming has received more attention than any other issue of late. A reasonable solution to the anthropogenic global warming issue has been articulated: massive increase in R&D in non carbon energy sources, including nuclear (see The Climate Fix by Roger Pielke jnr; The Long Death of Environmentalism by Michael Shellenberger and Ted Nordhaus).

I agree with the Shellenberger / Nordhaus article which concludes with 12 theses, 8 approaches that won't work and 4 approaches that will work.

Eight approaches that won't work:
  1. better, louder climate science won't transform the global energy economy
  2. fear / scare tactics backfire
  3. environmental justification won't work
  4. anti consumerism won't work
  5. regulation / pricing schemes won't achieve a clean energy economy
  6. climate change is not a traditional pollution problem
  7. a soft energy path (reduced green energy) is a dead end
  8. internalising fossil fuel cost won't work
Four approaches that will work:
  1. R&D into clean energy
  2. embrace nuclear power
  3. the State needs to invest in clean energy
  4. Big, centralised energy is the way to go, not Small is beautiful
But ocean acidification is a relatively understated problem which may lead to extreme marine life destruction through destruction of coral reefs. (see Elizabeth Kolbert's "Ocean Acidification"). Roger Pielke snr has long warned against the issue of ocean acidification as have scientists concerned about the future of Australia's Great Barrier Reef.

Several writers have pointed out that the widening gap between the world's rich and the world's poor (both in terms of money and access to energy) over rides environmental concerns. See Chris Foreman's On Justice Movements: Why They Fail the Environment and the Poor. Roger Pielke's iron law is correct, "that when policies focused on economic growth confront policies focused on emission reductions, it is economic growth that will win out every time" (The Climate Fix, p. 46).

Thomas Wells, in Debating Climate Change: The need for economic reasoning also argues that a pragmatic approach is far more likely to succeed than moralising about the state of the earth.

Poor people and indigenous people, "the wretched of the earth", usually desire modernity. Listen to Marcia Langton's Boyer lectures about how the mining industry, for all their faults, has done more for Australian aboriginals than the Australian government. You can't leave out the poor in your environmental considerations.

The problem with "the noble savage" metaphor is that our progressive Enlightenment values such as equality of women, non violent raising of children, against capital punishment, for democracy are repelled by the values of tribal hunter gatherer societies, once we scrutinise them carefully. Modern people aren't prepared to give up modern values and so "the noble savage" metaphor fails.

Bjorn Lomborg built his reputation initially around his book The Skeptical Environmentalist. Lomborg began by trying to refute Julian Simon's optimism for the future but ended by agreeing with him. Following that he developed the Copenhagen Consensus forums about the best way to spend money to solve world problems. However, Lomborg has come under a lot of criticism for inaccuracies in his work (which he fails to acknowledge) and promoting short term issues over longer term issues. I must admit that I like a lot of what Lomborg does but feel that the criticisms developed at Kare Fog's website, Lomborg Errors, do significantly weaken his case.

There are a few books around about the threat to biodiversity. If you prefer one written by an actual scientist then see Edward O Wilson's, The Future of Life (2003). Others, written by journalists without a strong background in science, include The Sixth Extinction (2014) by Elizabeth Kolbert and The Song of the Dodo (1997) by David Quammen).

I read Edward O Wilson's 12 dot point "strategy aimed at the protection of most of the remaining ecosystems and species" which is on pp. 160-64 of his book along with some other parts of his Ch 7 "The Solution". In summary:
  • Salvage the hotspots, 1.4% of the Earth's land surface protects 44% of known vascular plants and 36% of known mammals, birds, reptiles and amphibians.
  • Keep intact the 5 remaining frontier forests
  • Cease all logging of old growth forests
  • Save lakes and river systems
  • Define and save marine hotspots, eg. coral reefs
  • Complete the mapping of the world's biological diversity
  • include the full range of the world's ecosystems, eg. deserts, arctic tundras
  • make conservation profitable
  • use Genetic Engineered crops
  • initiate restoration projects, from the current 10% of protected land up to 50%
  • use zoos and botanic gardens to breed endangered species
  • support population planning
I still feel that technological risk taking is a sensible way for the human race to proceed (the proactionary principle critique of the precautionary principle, http://www.maxmore.com/proactionary.html).
People’s freedom to innovate technologically is highly valuable, even critical, to humanity. This implies several imperatives when restrictive measures are proposed: Assess risks and opportunities according to available science, not popular perception. Account for both the costs of the restrictions themselves, and those of opportunities foregone. Favor measures that are proportionate to the probability and magnitude of impacts, and that have a high expectation value. Protect people’s freedom to experiment, innovate, and progress.
R&D, nuclear power and genetic engineering are important parts of the solution. Humans are a tool making species and irreversible change has always been normal. But technological optimism as a blind faith is not a good outlook. Be neither a religious environmental alarmist nor a religious technological optimist. Rather explore the facts of the real state of the earth, without hype.

The Planetary Boundaries analysis asserts that we are headed towards environmental tipping points in a number of fields: climate system, ocean-acidification, ozone depletion, phosphorous levels, land use change, biodiversity loss, nitrogen levels, freshwater use, aerosol loading and chemical pollution. For some critical discussion of this view see Nordhaus, Schellenberger and Blomqvist. The Planetary Boundaries Hypothesis: A Review of the Evidence. They assert that in most cases these are not "tipping points" in a global sense but need to be evaluated according to local conditions. However, they do agree that Climate Change and Ocean-acidification are in grave danger of reaching tipping points.

So, which authors are on the track of documenting the real state of the world? How will issues such as rich-poor gap, energy, biodiversity, global warming etc. work themselves out in the future? I've become very interested in the writings of Vaclav Smil who has written Harvesting the Biosphere: What we have taken from nature (2012) and Global Catastrophes and Trends: The Next 50 years (2008). I've only read selected extracts from these books so far and feel that he is neither an environmental alarmist or denier but someone striving to work out the real state of the world.

Some of Smil's other writings (about energy, nitrogen / food and oil - see references) could provide extremely valuable background knowledge about how to think about these issues.

ABC's Vision Impaired by Solar Hype and Hope

Critique of the ABC's "Power to the People", 4 corners, 7th July 2014

The ABC narrative goes something like this:
  1. Anthropogenic Global Warming is a huge problem, so we have to reduce our carbon outputs.
  2. PM Tony Abbott and Greg Hunt (Environment Minister) are not serious about tackling this problem. As well as scrapping the carbon tax they are now threatening to scrap the 20% renewable energy target as well
  3. Renewables, with a focus on solar power is a vital way forward for Australia. We are in grave danger of being left behind the rest of the world as they latch onto the clean energy market. (jobs, economic development)
  4. Solar thermal and solar PV can make a big difference now provided you have some insight, determination and care for the planet.
  5. In the not so distant future we will develop a radically different electricity system, with community micro-grids and technology that allows buildings to create and store their own energy.
Geoff Russell has already written a critique, Four Corners and its field of dreams, of this program on the pro-nuclear Brave New Climate site. He correctly takes the ABC to task for not doing the maths required for a critical assessment of the potential of solar power (point 4 above). In his view, consistent with the Brave New Climate perspective, nuclear power can do the job of serious carbon reduction much more effectively than solar:
By comparison, France built an essentially carbon free nuclear electricity system in under 20 years. So while Australian electricity generates 850 grams of CO2 per kilowatt hour, France is down around 70 grams per kilowatt hour and she’s been there since 1990. 
My research also indicates that there are a huge range of problems with solar and wind power. These problems were either glossed over by the ABC or not even mentioned. Nevertheless, the ABC claims to be well researched with dozens of supporting links revealed when you press the Show Background Information button on their website. In such a long standing polarised debate it is always possible to find lots of support for your preferred position. In omitting consideration of core issues the ABC has been far too selective, blinkered and unreflective in their focus.

The problems I refer to are energy returned on energy input (EROI or ERoEI) for renewable technologies, intermittency, diffuseness, storage, integration into the grid (the nature of baseload and peaking) and capacity issues. The capacity factor is how much electricity a generator produces relative to the maximum it could produce.

These issues, some of them technical, should form the core part of an informed program about the role of renewables in the energy mix. But apart from misleading claims about the storage issue most of them are not even mentioned in the ABC program. They have chosen to be warriors in the cause of renewable energy before completing the research that has to be done to be an informed warrior.

A good, free online reference to these more complex technical issues is Energy intensities, EROIs, and energy payback times of electricity generating power plants. Warning: it contains something missing from the ABC program - mathematical rigour.

Also see the book reviews on Brave New Climate for (an unfortunately too expensive book) Energy in Australia: Peak Oil, Solar Power and Asia's economic growth by Graham Palmer. (1) Precis by Graham Palmer (2) Review by John Morgan

This summary by Peter Lang (first comment after the book review) illustrating the relatively low values for solar and wind of the energy returned on energy invested (ERoEI) could form the starting point of a further discussion of the problems involved with solar and wind power.
  • PV (Germany) 2.3
  • Solar thermal 9.6
  • Wind 4
  • Hydro (NZ) 35
  • Coal 29 – 31
  • Gas 28
  • Nuclear 75 – 105
The ABC program is a complete fail with respect to these core issues of energy transformation. Here is a sample, referring to Canberra's Royalla Solar Farm:
STEPHEN LONG: And still tiny by world standards.

It costs a lot to build a plant like this, and that does feed into electricity prices, but in the medium term, the energy will be cheaper because the fuel input, sunlight, is free.

SIMON CORBELL: The economics is a no brainer and it also drives down the cost of electricity more generally in the market because, often, at times of peak demand, renewables is the cheapest source of energy into the electricity market
This could only be described as manipulative journalism. By mentioning that sunlight is free, and ignoring the other fixed production cost of the panels and labour as well as the relatively poor return due to the diffuseness and intermittency of sunlight, the impression is given that energy returns on inputs for solar power is an economic "no brainer". But the ERoEI figures above demonstrate the falseness of that claim.

Furthermore, I think the critique of the ABC needs to go beyond the technical issues. Their full message is for a clean, green and decentralised future, point (5) above. A nuclear energy future is not decentralised and so it is important to address that claim as well. The ABC claim is a political / cultural message that such a decentralised, energy future is desirable and possible, the cultural appeal of the long standing "small is beautiful" movement.

The ABC program suggested strongly, towards the end, that centralised electricity through the traditional grid would be replaced in time with decentralised micro-grids. This thought bubble inspired the "revolutionary" title of the program, "Power to the People".

Consider these extracts, I have emphasised the hype:

a) From the section about the Orange City Bowling Club in the central west of New South Wales.
STEPHEN LONG: An electricity bill that was running at $116,000 a year has fallen by more than a third, and the investment in rooftop solar will pay for itself in three years.

This humble bowling club may be part of a paradigm shift, a new era for the economy.

Danny Kennedy calls it the rooftop revolution, power to the people.

DANNY KENNEDY: What we've had is these big power stations at the middle of a hub and spoke model, shunting electrons down a one-way fire hose, telling us what we should pay for it.

What we're getting now is the ability to participate in the creation of electricity. We're going to have our own power plants on our own roofs. There's going to be a community level storage system, a solar farm or a wind farm out the back, and all those are going to take part in the creation of electricity and the economics of electricity, and it's all going to be managed through software and information communications technology.
b) From futurist Jeremy Rifkin:
JEREMY RIFKIN: We now have millions and millions of small players, home owners, small businesses, cooperatives, even large businesses that are producing their own solar and wind generated green electricity at near zero marginal cost.

In 10 years from now, 15 years from now, we'll have tens of millions of local sites producing green electricity on micro-grids
c) The section discussing the aftermath of superstorm Sandy:
STEPHEN LONG: When super storm Sandy struck the United States in 2012, Americans discovered what it's like when the power grid breaks down.

Millions of people across the east coast were left for days without electricity: no light, no heat and no communications.

RICHARD KAUFFMAN, CHAIRMAN, ENERGY AND FINANCE, NEW YORK STATE: The thing that people had the hardest time with during Sandy was the fact that they were cut off from communications. If you're without power for days, it is, not just inconvenient, but it really feels like you can't live your life.

Individuals and communities want to have more and more control over their energy system. We again saw this after Sandy where communities have asked for their own micro-grids because they don't want to be as reliant upon the grid.

STEPHEN LONG: Former investment banker, Richard Kauffman, is known as New York's Energy Tsar. He's overseeing a move to decentralised electricity.

RICHARD KAUFFMAN: In the last 10 years, we've invested $17 billion just to keep the grid as it is. And, in the next 10 years, if we keep just doing exactly as we've been doing, it's, we have to invest another $30 billion.

The Empire State is instead planning a radically different electricity system, with community micro-grids and technology that allows buildings to create and store their own energy.

RICHARD KAUFFMAN: It used to be that you had to get the electricity that came through the central grid because that was the only alternative.

Well that's not true anymore, so we have had, across a whole range of industries, the benefit that customers are now in charge and the technology exists now for that to be true in the power sector.

The cost of all these solutions are going down, while the cost of the traditional central station power and distribution systems goes up.
The ABC is promoting a decentralised field of dreams here. Here is a rebuttal to their views found on line. DG stands for distributed generation. Emphasis added.
If you want to know what utilities actually object to about DG, it is policies that functionally require them to purchase power from solar homeowners at $0.30/kWh when they don’t need it instead of buying it on the wholesale market for $0.04/kWh when they do. The result is not just less-profitable utilities but also higher rates for the vast majority of ratepayers. A recent California Public Utilities Commission study concluded that by 2020 the state’s net metering programs would increase rates by a billion dollars annually.

That’s not to say that the growth of renewable energy is not disruptive—just not in the way its advocates claim. Look at just about any place that has achieved significant deployment of renewable electricity, and what you find is that the vast majority comes from large, utility scale installations, not rooftop solar or any other behind-the-meter generation source. Even Germany gets over three-quarters of its renewable generation from large-scale wind, hydro, and biomass.

Given the current state of renewable technology and the scale of generation necessary to run a modern economy, these basic dynamics appear unlikely to change anytime soon. Take a peek at any of the dozens of scenarios produced by renewables advocates that claim we can run the U.S., Europe, or the world largely on renewables, and what you find is that most generation comes from massive industrial scale wind and solar developments from North Dakota to the North Sea—not DG.

In fact, a renewables-powered future will probably require more centralized generation, not less. Achieving significantly higher penetrations of renewable energy will require transmitting electricity over hundreds or thousands of miles from where large amounts can be generated to places where it will be consumed. Renewables champions may talk small-scale DG, but what they intend to build is every bit as centralized as the centralized power sources we have today.

Ultimately, what is disrupting the existing utility model is not the distributed nature of renewables, it is their intermittent nature, and the policies necessary to make them viable. Heavy public subsidization of the capital costs of wind and solar, combined with preferential purchase requirements for the power they generate, ensure that the marginal cost of wind and solar will always be lower than just about anything else when the wind is blowing and the sun is shining. Hence, Germany simultaneously boasts the highest retail electricity prices in Europe and the lowest wholesale prices—not because the power costs less to generate but because most of the cost has been shifted elsewhere. In Germany, expensive, highly subsidized, intermittent renewables generation has driven wholesale prices so low that the utilities that must manage the grid and operate conventional power plants can no longer operate profitably. This, not cheap distributed solar, is what is disrupting the utility industry here and abroad.
- The Revolution won't be distributed (2014) 
Consistent with it's decentralisation thesis the ABC program provides us with a false idea about the nature of disruptive technologies:
MATTHEW WARREN: Oh look, I think we are seeing in the energy industry, it's going through a transformation that's not dissimilar to telephony to retail to newspaper media and that is, we're seeing, you know, quite radical transformation that is driven by technology and driven by changing market conditions.

DANNY KENNEDY: It's disruptive like media was disrupted a decade ago.

Once upon a time, the ABC and New York Times were all the news that was fit to print and they shunted the news of the day down the one way fire hose, and now we use social media and Twitter and whatever else to co-create what is the news stream and what makes for big news.

And, the economics, we know well, has been completed transformed. That's coming to electricity. The coal and other protected, vested interests of Australia are going the way of the Dodo if they don't adjust to this reality.
The important point about digital disruptive technologies is that they start out cheaper than established technologies. Mobile phones and online journalism start out cheaper than the media which they threaten to displace. The reverse situation applies to solar and wind power, which are still far more expensive than fossil fuels. Moore's law does not apply to energy technology as the ABC is suggesting.

Is a 20% Renewable energy target a good idea?

We need both more energy, particularly for the world's energy poor, and more clean energy, meaning, in part, energy produced without or with reduced CO2 emissions, also known as decarbonisation of the energy supply.

The program begins with Kerry O'Brien voicing the fear that the Abbott government is threatening to cut the 20% Renewable Energy Target (RET).

Why would Abbott and Hunt contemplate this? Well, the real reason, not spelt out clearly in this ABC program, is that renewables are expensive and so have to be subsidised.

The Australian political reality is that ongoing political uncertainty (no one knows what will happen electorally in the future) threatens renewable energy subsidies. As long as renewable energy can't compete with fossil fuels in the capitalist market place then it will remain dependent on subsidies whose delivery will remain politically uncertain.

Roger Pielke jnrs iron law says (assuming the continuation of the capitalist system) that when tough decisions have to be made economic issues will always trump environmental issues. He's right. The Australian people won't support a political system which raises or even vaguely threatens to raise energy prices to the point which either cuts deeply into our standard of living or makes us uncompetitive on the world stage. The election of the far from popular Tony Abbott as PM, who promised to rescind the carbon tax introduced by the ALP, demonstrates that.

So how to proceed? What policies do I support, which may be capable of gaining political traction? (1) Intelligent subsidies where there is justified hope for a rapid price reduction in the given renewable (2) Much more emphasis on Research, Development and Demonstration (RD and D) to bring the price of renewables down. Setting a target with a strict timeline does not necessarily promote these policies. I think the critique of the Abbott government's policies by Roger Pielke jnr (Australia's Climate Follies) has far more substance than the ABC critique.

Given that renewables such as solar and wind remain far more expensive (despite considerably cost reduction to date) than nuclear which in turn remains more expensive than fossil fuels then the emphasis needs to be on RD and D to bring the price of clean energy alternatives down to a level where they can compete.

Judith Curry message to IPCC

Judith Curry message to IPCC:
Once you sort out the uncertainty in climate sensitivity estimates and fix your climate models, let us know. Then please do the hard work of understanding regional vulnerability to climate variability and change before you tell us what constitutes ’dangerous’ climate change. And let us know if you come up with any solutions to this ‘problem’ that aren’t worse than the potential problem itself.

Pielke snr summary of climate issues

I'm copying his summary here without the extensive links. Here is the original.

1) There has been global warming over the last several decades. The ocean is the component of the climate system that is best suited for quantifying climate system heat change. The warming has been less than predicted by the multi-decadal global model predictions.

2) The use of a global annual average surface temperature is an inadequate metric to quantify global warming and cooling. The documentation of the poor siting quality over land is one reason it is such a poor metric.

3) The involvement of citizen scientists to document the siting quality is a very significant achievement

4) The human addition to CO2 into the atmosphere is a first-order climate forcing. It is the largest annual-global averaged positive human radiative forcing

5) However, global warming is not equivalent to climate change. Significant, societally important climate change, due to both natural- and human- climate forcings, could occur even without global warming or cooling.

I propose these definitions be adopted in our statement

“Global Warming” is an increase in the global annual average heat content measured in Joules.

“Climate Change” is any multi-decadal or longer alteration in one or more physical, chemical and/or biological components of the climate system.

6) The correct summary statement on climate, in my view, is that
Natural causes of climate variations and changes are important. In addition, the human influences are significant and involve a diverse range of first-order climate forcings, including, but not limited to, the human input of carbon dioxide (CO2). Most, if not all, of these human influences on regional and global climate will continue to be of concern during the coming decades.

In addition to greenhouse gas emissions, these other first-order human climate forcings that are important to understanding the future behavior of Earth’s climate are spatially heterogeneous and include the effect of aerosols on clouds and associated precipitation, the influence of aerosol deposition (e.g., black carbon (soot), and reactive nitrogen), and the role of changes in land use/land cover. Among their effects is their role in altering atmospheric and ocean circulation features away from what they would be in the natural climate system. As with CO2, the lengths of time that they affect the climate are estimated to be on multidecadal time scales and longer.
7) Natural variations and longer term change have been significantly underestimated. Also, climate prediction is an initial-value problem

8) Attempts to significantly influence impacts from regional and local-scale climate based on controlling CO2 emissions alone is an inadequate policy for this purpose. With respect to CO2 [and for all other human climate forcings], the emphasis should be on supporting technological developments to mitigate these threats

9) Policymakers should look for win-win policies in order to improve the environment. The costs and benefits of the regulation of the emissions of CO2 into the atmosphere need to be evaluated together with all other possible environmental regulations. The goal should be to seek politically and technologically practical ways to reduce the vulnerability of the environment and society to the entire spectrum of human-caused and natural risks including those from climate.

10) Global and regional climate models have not demonstrated skill at predicting multi-decadal changes in climate statistics on regional and local climate in hindcast studies

11) What we recommend in our Pielke et al (2012) paper in terms of an approach to mitigation and adaptation is, as written in its abstract,
“We discuss the adoption of a bottom-up, resource-based vulnerability approach in evaluating the effect of climate and other environmental and societal threats to societally critical resources. This vulnerability concept requires the determination of the major threats to local and regional water, food, energy, human health, and ecosystem function resources from extreme events including climate, but also from other social and environmental issues. After these threats are identified for each resource, then the relative risks can be compared with other risks in order to adopt optimal preferred mitigation/adaptation strategies.

This is a more inclusive way of assessing risks, including from climate variability and climate change than using the outcome vulnerability approach adopted by the IPCC. A contextual vulnerability assessment, using the bottom-up, resource-based framework is a more inclusive approach for policymakers to adopt effective mitigation and adaptation methodologies to deal with the complexity of the spectrum of social and environmental extreme events that will occur in the coming decades, as the range of threats are assessed, beyond just the focus on CO2 and a few other greenhouse gases as emphasized in the IPCC assessments.”
And finally:
When I return, I look forward to assessing further the above issues, and also invite readers on my weblog to submit guest posts to appear after I am back, which refute any of the above conclusions.

Bob Brown exaggerated

Attribution of extreme climate on anthropogenic global warming
Remembering back to the Queensland floods and the attempt by Bob Brown to blame this onto the coal industry. IMO he tried to make something sound certain which was very, very far from certain.
GREENS leader Bob Brown has pinned the blame for the Queensland floods on the coal industry.

He says the sector's contribution to global warming is responsible for the extreme weather conditions causing the floods.

Senator Brown said yesterday the "coal barons" should be made to pay for the damage caused by natural disasters, with half of Canberra's planned mineral resources rent tax set aside for a repairs fund.

"Burning coal is a major cause of global warming," he said. "This industry, which is 75 per cent owned outside Australia, should help pay the cost of the predicted more severe and more frequent floods, droughts and bushfires in coming decades."

Scientists had concluded that the floods were caused by record high temperatures in the oceans around Australia.

"It is unfair that the cost is put on all taxpayers, not the culprits," said Senator Brown, who was stranded by the floods in Tasmania for two days.
- Coal barons must pay for flood damage, says Bob Brown
The problem is finding reliable scientific sources that you can trust wrt the global warming issue.

I am neither an alarmist or a denier. I did spend a reasonable amount of time a while ago searching for experts I could trust. It's very hard to describe that search process. So, of course it's possible that I have ended up trusting the wrong experts. My own opinion is worth little. I'm reliant on the experts and my only hope here is that I'm good at picking the right experts.

But FWIW the experts I have ended up with are Pielke snr, Pielke jnr, Richard Tol and Judith Curry. So, I'm just publishing a short summary by Judith Curry here on this question, since it seems to me to recognise the complexity of the subject and achieve some balance where balance is required:

Judith Curry, chair of Georgia Institute of Technology’s School of Earth and Atmospheric Sciences:
The substantial interest in attributing extreme weather events to global warming seems rooted in the perceived need for some sort of a disaster to drive public opinion and the political process in the direction of taking action on climate change. However, attempts to attribute individual extreme weather events, or collections of extreme weather events, may be fundamentally ill-posed in the context of the complex climate system, which is characterized by spatiotemporal chaos. There are substantial difficulties and problems associated with attributing changes in the average climate to natural variability versus anthropogenic forcing, which I have argued are oversimplified by the IPCC assessments. Attribution of extreme weather events is further complicated by their dependence on weather regimes and internal multi-decadal oscillations that are simulated poorly by climate models.

I am unconvinced by any of the arguments that I have seen that attributes a single extreme weather event, a cluster of extreme weather events, or statistics of extreme weather events to anthropogenic forcing. Improved analysis of the attribution of extreme weather events requires a substantially improved and longer database of the events. Interpretation of these events in connection with natural climate regimes such as El Nino is needed to increase our understanding of the role of natural climate variability in determining their frequency and intensity. Improved methods of evaluating climate model simulations of distributions of extreme event intensity and frequency in the context of natural variability is needed before any confidence can be placed in inferences about the impact of anthropogenic influences on extreme weather events.

Judith Curry interview on climate change

The IPCC May Have Outlived its Usefulness

 Some extracts:

 OP: What are your personal beliefs on climate change? The causes and how serious a threat climate change is to the continued existence of society as we know it.

 JC: The climate is always changing. Climate is currently changing because of a combination of natural and human induced effects. The natural effects include variations of the sun, volcanic eruptions, and oscillations of the ocean. The human induced effects include the greenhouse gases such as carbon dioxide, pollution aerosols, and land use changes. The key scientific issue is determining how much of the climate change is associated with humans. This is not a simple thing to determine. The most recent IPCC assessment report states: “Most [50%] of the warming in the latter half of the 20th century is very likely [>90%] due to the observed increase in greenhouse gas concentrations.” There is certainly some contribution from the greenhouse gases, but whether it is currently a dominant factor or will be a dominant factor in the next century, is a topic under active debate, and I don’t think the high confidence level [>90%] is warranted given the uncertainties.

 As I stated in my testimony last year: “Based upon the background knowledge that we have, the threat does not seem to be an existential one on the time scale of the 21st century, even in its most alarming incarnation.”

OP: You are well known in climate and energy circles for breaking from the ranks of the IPCC and questioning the current information out there. What do you see as the reasons for the increase in skepticism towards global warming over the last few years.

JC: Because of the IPCC and its consensus seeking process, the rewards for scientists have been mostly in embellishing the consensus, and this includes government funding. Because of recent criticisms of the IPCC and a growing understanding that the climate system is not easily understood, an increasing number of scientists are becoming emboldened to challenge some of the basic conclusions of the IPCC, and I think this is a healthy thing for the science.

OP. What are your views on the idea that CO2 may not be a significant contributor to climate change? How do you think such a revelation, if true, will affect the world economy, and possibly shatter public confidence in scientific institutions that have said we must reduce CO2 emissions in order to save the planet?

JC: Personally, I think we put the CO2 stabilization policy ‘cart’ way before the scientific horse. The UN treaty on dangerous climate change in 1992 was formulated and signed before we even had ‘discernible’ evidence of warming induced by CO2, as reported in 1995 by the IPCC second assessment report. As a result of this, we have only been considering one policy option (CO2 stabilization), which in my opinion is not a robust policy option given the uncertainties in how much climate is changing in response to CO2.

OP: Do you believe that the language used in papers and at conferences is a problem? The public just wants straight answers to questions: Is the climate warming, By how much, and what will the effects be? Scientists need to step out from behind the curtain and engage the public with straight answers and in their own words. Is this achievable, or is climate science too complex to be explained in laymen’s terms? Or is it because even climate scientists can’t agree on the exact answers?

JC: I think the biggest failure in communicating climate science to the public has been the reliance on argument from consensus. We haven’t done a good job of explaining all this, particularly in the context of the scientific disagreement

The Climate Fix by Roger Pielke jnr

Here is my summary of his main points so far:
  1. we will need VASTLY more energy in the future
  2. the amount of CO2 we pump into the atmosphere is a big problem - both AGW and biogeochemical effects
  3. so we have to decarbonise the energy supply, aka reduce carbon intensity C output / energy consumed (see Kaya identity section for more detail here)
  4. decarbonisation makes sense from other perspectives too, eg. energy security for some countries (from a policy perspective it is important that there are some short and intermediate term gains from the pain or costs of policy)
  5. the public will not accept a big C tax designed to change energy consumption behaviour - they will vote out any party that introduces it
  6. small steps are better than grandiose plans that end up being rejected
  7. there is not a linear relationship between climate science and government policy, Scientific findings in complex social issues do not dictate policy. Politics in a democracy requires public support. A non linear or oblique approach might work. The direct approach has failed (Copenhagen)
  8. the public will accept a small dedicated C tax (rising slowly over time) to fund R&D; there is consistent public support for some action on climate change but not dramatic action which will alter standard of living
  9. We need more R&D because present technology is not sufficient to do the CO2 reduction that is required – taking into account future economic growth and removal of CO2 from the ocean to reduce harmful biogeochemical effects, as well as from the atmosphere
  10. Since the above steps do not provide a guarantee for targeted CO2 reductions then a backstop is also required
  11. CO2 air capture and storage (remediation) is a potential backstop, which could reshape the climate debate, one of the targets for further R&D

climate: the triumph of the blogosphere

As well as Judith Curry's excellent climate blog, Climate etc I just discovered that Richard Tol, economist, has a climate blog too: IPCC5 KEY ECONOMIC SECTORS AND SERVICES

He is an IPCC author who is critical of many aspects of the IPCC and has a wicked sense of humour to boot, for instance:
I would add two things, though. Firstly, Pachauri apparently does not trust IPCC authors and editors to be mature enough to say sensible things to journalists. Most of us have PhDs, after all, and many are full professors. We might just slip into juvenile language and compare people to Hitler, accuse them of practicing voodoo, or recommend they rub asbestos in their faces. Better to leave communication to the IPCC leadership, who would never say such things
- Letter from Pachauri
Rajendra Pachauri is Chair of the IPCC.

The blogosphere is maturing as more expert people who have become impatient with formality, bureaucracy and who have a desire to widen the democratic process come on line. My other favourite climate blogs are Pielke jnr and Pielke snr.
