The global warming deniers 04 July 08
The arguments of climate sceptics have largely been moulded by a far more sinister force - the US-based conservative think tanks
I am finding it increasingly difficult to maintain my optimism that we can stabilise global temperature increases below the “danger level” of 2°C. First, there is no sign that emissions are being reduced; rather, the opposite is happening. Second, it is becoming clear that the danger level for temperature increase is a good deal lower than 2°C.
The Arctic Sea ice cover is already approaching a new low. The new topic of speculation is not whether the Arctic ice will disappear completely in the summer months by 2080, but whether this will happen by 2018. An ice-free North Pole will have a significant effect on the planet’s energy balance, given the important role this huge white “mirror” plays in reflecting incoming solar radiation. Once it is gone, the warming process can only speed up further. Already, a new study suggests that an ice-free Arctic Ocean will dramatically increase warming in surrounding land areas, accelerating the degradation of permafrost and resulting in huge releases of carbon and methane – driving yet more warming. Setting a danger level of 2°C, as the UK and EU have done, now looks dangerously optimistic.
The Intergovernmental Panel on Climate Change (IPCC) reported last year that emissions cuts within a decade could still keep temperature hikes below 2°C. But global emissions are rising year on year, not falling. Many climate models are underpinned by an assumption of 1.5 per cent increases annually in carbon releases. Instead, they have been running at more than 2 per cent.
In the words of the Tyndall Centre scientist Kevin Anderson: “Since 2000 the world has gone ballistic in terms of carbon emissions.” Anderson has recently revised his projections for climate change and now thinks that the “best we can expect” is stab ilising atmospheric concentrations at 650 parts per million CO2 equivalent, equating to warming of about 4°C. He suggests we “mitigate for 2°, but adapt for 4°”.
Adapting to 4°C of warming would be quite a challenge. With this level of temperature change, we can expect a huge increase in drought-prone zones, a mass extinction of half or more of the life on earth, hundreds of millions of refugees from areas deprived of fresh water or inundated by rising seas, and widespread starv ation due to food and water shortages.
The Stockholm Network’s Carbon Scenarios report (which I helped draft) reaches a similar conclusion, projecting a warming of nearly 5°C if global policy on climate continues to fail. Against this terrifying backdrop, the denial lobby flourishes, its success almost calling into question the capacity of mankind for reasoned thought.
Nigel Lawson’s dreadful book, laughably entitled An Appeal to Reason, has been riding high in the sales charts and is only one of several denialist tomes on global warming. The last time I looked, four out of five of Amazon’s top sellers on climate were penned by deniers. And these are not just views from the fringe. A MORI poll reported by the Observer last month found six out of ten people think, wrongly, that “many scientific experts” disagree on whether human beings are causing climate change. Four out of ten people asked believed that the impact had been exaggerated.
“sceptics are supported by politically powerful conservative think tanks funded by wealthy foundations and corporations”
Many climate-change sceptics like to think they are proudly independent people, refusing to be cowed by UN-sponsored orthodoxy from the IPCC. In fact, the arguments of climate sceptics have largely been moulded by a far more sinister force – the US-based conservative think tanks. A recent academic survey of environmentally sceptical books found that 92 per cent were linked with these think tanks, which include the Heritage Foundation, the Cato Institute and the Competitive Enterprise Institute. Since the early 1990s, these and other industry-funded front groups have been leading an anti-environmental backlash, changing the tenor of the political debate on environmental issues and bombarding the media and the public with disinformation.
The authors of the study, published in the June edition of a journal called Environmental Politics, argue that, far from being a true grass-roots movement, “environmental scepticism is an elite- driven reaction to global environmentalism, organised by core actors within the conservative movement”. The “self-portrayal of sceptics as marginalised ‘Davids’ battling the powerful ‘Goliath’ of environmentalists and environmental scientists is a charade”, given that the “sceptics are supported by politically powerful conservative think tanks funded by wealthy foundations and corporations”.
Next time someone insists global warming isn’t happening, ask yourself where their views come from – and whose interests they serve.

Dear Mark.
Don’t worry so much about the future.
I am more in terested in your position on what to do, rather than whether to do something.
If I am not wrong your position has much in common with the Stern report and the Indian National Action Plan on Climate Change.
I cannot find the article you wrote in the New Statesman when I was in Cambridge sometime in June, where you argued in effect that we must leave the carbon market to the polluters.
I think it is time you got off the fence and committed to global cap and share.
Will you read my blog of today, which I repeat below? I do hope you change your mind and if you get a chance to write in the New Statesman again, you come out loud and clear in favour of a democratic Convention bank under Article 11.
The rest below is from my blog.
The UK’s Stern Review commissioned by ex-Prime Minister Blair and the Indian Prime Minister Man Mohan Singh’s National Action Plan on Climate Change have much in common: there is concern about climate change, a willingness to act based on scientific evidence, a recognition that a neo-liberal economic approach will not do the trick and that moral commitment and government intervention is required; also an admission/reiteration that developed countries must do the bulk of the reductions. One of Stern’s two scenarios envisages developed countries taking responsibility for cuts equal to 90% of their 1990 levels by 2050. The Indian PM also promises that India’s per capitum emissions will never exceed those of developed countries. Convergence is thus on both agendas. Both authors however steer clear of our most important concern in the run up to Copenhagen: financing. Stern and the PM only touch tangentially on how to finance the transition. There is a glaring omission in both reports of the need for a democratically accountable financing mechanism under Article 11 of the Convention to replace the woefully inadequate interim arrangements.
Both authors subscribe to the view that a global quantity constraint can be achieved without command and control. Stern on p.471 says: “We argued in Chapter 14 that in the long-term, a global quantity constraint is the appropriate guide for policy-making. A global quantity constraint can be used to drive intergovernmental trading of emissions quotas, and this has already been adopted within the current multilateral framework, the Kyoto Protocol. Moreover, as we explained in Chapter 14, a key benefit of trading schemes for emissions quotas is that they allow the cost-effectiveness (via a common price) and distributional equity of action (via flows based on quota allocations) to be managed separately but simultaneously. In a global and comprehensive system of quota trading, the initial allocation of national limits on emissions affects the distributional equity of the scheme, but not the equilibrium distribution of emissions reductions, the market-determined carbon price or the costs of abatement. Therefore these allocations represent the overall level of responsibility that each country undertakes, rather than the emissions reductions that are required to physically occur within its borders.” This is a carbon market administered by the UNFCCC but not managed.
The PM says: “The principle of equity that must underlie the global approach must allow each inhabitant of the earth an equal entitlement to the global atmospheric resource. The NAPCC will be guided by the following principles: - Protecting the poor - Achieving national growth objectives - Devising efficient and cost-effective strategies for end-use demand side management - Deploying appropriate technologies for adaptation and mitigation - Engineering new and innovative forms of market, regulatory and voluntary mechanisms to promote sustainable development. (2. principles, p.2) …Carbon market financing would enable access to technologies where there are higher investment costs, or higher economic cost of the required energy service, or both.” (3.3.1.1. costs and financing, p.24)
Thus both authors think the free market will set prices for emission permits and that reductions will be financed by global capital outside of their national boundaries.
But even if you set a global quantity constraint, and even if you have a constitution at Copenhagen that explicitly allows each inhabitant of the earth and equal entitlement to the global atmospheric resource, you will not achieve the objective of the convention through the free carbon market.
We saw this under the first phase of Kyoto when the polluters set their own prices in the European Trading System for example. Europe did hardly any better than the US in the first Kyoto commitment period – and in fact if aviation and shipping are included both exceeded their 1990 emissions and emissions rose absolutely in both regions every year since Kyoto came into force in 2005.
Commitments are nothing without enforcement and enforcement requires agency.
If we think a global solution is needed we must put in place the mechanism to manage it. If we think each sovereign state must do its own thing within a vague scientific consensus, then we must say so, and not bother with a Convention. But you cannot say that the global market which is 100% based on fossil fuels today will be the benign agent of the transition. This is at best wishful thinking and at worst the continued facilitation of business as usual which at this stage is very irresponsible not only because we will suffer the effects of climate change but because the poor who are ostensibly the reason why Prime Ministers and advisors do their work will get rapidly much poorer. The interest of global corporations under capitalism will always be to minimise their cost. A market based pricing mechanism for emission permits in which these polluters are the only participants and set their own price of permits based on their competing willingness to pay will always shadow global fossil energy prices. In other words, the poor will continue to be exploited and ignored and fossil fuels will continue to be more preferable to labour as the basis of the global economy.
If you are serious about the poor and about climate change therefore you need to limit the access of polluters to fossil energy effectively. This can only be done under the Convention. We need a global constitution under the UNFCCC that authorises the Conference of the Parties to set global quantity constraints (Stern), based on the principle of equity that allows each inhabitant of the earth an equal entitlement to the global atmospheric resource (INAPCC) PLUS a democratically controlled bank managed on the basis of 1 party one vote to do the work in the transition period 2012 to 2040 and beyond. This is what G77&China group discussed at the last working group on long-term cooperative action and they have asked anyone and everyone to provide details of how this will work between now and the next meeting in Accra. The results will be the basis for the negotiations at Poznan. In 1995 when we wanted a democratically accountable financing mechanism under the Convention we were defeated. Instead we got an interim arrangement under Article 11. But Article 11 is as much up for review in Poznan and Copenhagen as is Kyoto and this time really if Stern is anything to go by, there is not a negotiation about what, but about how. We all want to achieve the objective of the convention, and we all want equitable rights to the global commons. Now all that is left is to create the agency that can make polluters pay, an agency with the authority to sell permits in the national territories of Annex 1 developed countries.
Let us not beat around the bush. This is the real controversy. Whether a new world climate bank can manage developed country economies.
That is why the G8 is so desperate to create a new aid-type bank for adaptation, mitigation, technology, anything in fact as long as we are prevented from selling OUR emission permits in THEIR national territories.
And do not forget. We have not even begun to sell them the retrospective permits for the emissions from 1900 onwards.
Whether the US join in or not, right thinking Prime Ministers and right thinking advisors can throw their weight behind the creation of an accountable financing mechanism such as a global climate bank under Article 11 with a remit to sell emission permits at one thousand times today’s carbon market price. This will hit polluters hard in their own national territories which is where it matters. We do not want their investment. We want our money.
Developing countries can easily concede as the PM has done in the INAPCC that our emission level will never exceed that of developed countries. As the INAPCC says, there is enough for everyone’s need but not for everyone’s greed.
Postscript
In place of the global economy during the transition period 2012 to 2040 and after we will have the incommensurability of ecological quality.
All human beings want quality but we cannot currently enforce it in the face of the massive juggernaut of fossil energy based industry. We know that the middle class has just five years to give up its exploitative ways. We know that there will be no more international aviation, and no more international shipping. Why not just say it?
The poor will inherit the earth. We all know perfectly well that there is enough for everyone’s need but not for everyone’s greed. It is lovely having a society of equals. It is not communism, which was command and control for national growth. It is a society of equals where each family has a garden. 5000 Euros equivalent per year probably, generated with local resources. Incommensurable ultimately, but nice.
Please read my blog of 3rd July to see the emission permits per annum the Convention bank will sell on behalf of the world’s citizens in the period 2012 to 2040.

Oh God yes we are all going to die. I don’t know where to turn. We are all going to die. Painfully, slowly and we deserve it. The polar bears first and then the penguins and then the innuits and then us. What can be done? My hands are cracked with all the hand wringing, it’s awful. The IPPC are right we are all going to die, Painfully and slowly. What can be done? Thank God for one such as you and the Enfield division of the intergalactic save Earth campaign which will fight this scourge. Phasers on kill troops especially those from the Enfield sector. We are gonna fight these alien masses and win. I’ve watched UFO and the persuaders and by Sunday afternoon before four o clock we can defeat the menace. Keep up the good work especially those in the Enfield sector.

Next time someone insists global warming IS happening, ask yourself where their views come from – and whose interests they serve.
Let’s see if we can find some beneficiaries …
Well, the environmentalists will benefit. They will gain more supporters and have more influence.
Big business will benefit. Many have thousands of employees who will now all be trying to save energy and hence reduce the company’s energy costs. Many companies will be able to expand into the “eco-friendly” arena by making wind turbines, electric motors, generators, low energy cars, fuel cells etc.
Oil companies will benefit. Yes, they will sell less oil but they should be able to sell it at a much higher price. So with less work they will make more profit and the oil will last much longer.
Advisors to governments and big business on Climate Change will obviously benefit. As will people who give talks on Climate Change to invited audiences. Anyone smart enough to see a business opportunity in the trading of carbon credits will quickly become a multi-millionaire. The business requires no manufacturing effort or stock, only a modest amount of office staff and, all being well, governments will make it compulsory thus maximising revenue. Only a very small “rake off” will generate millions. (Anyone spring to mind?)
Governments will benefit. They have been trying to find a popular tax for years. This could be the opportunity they have been waiting for. They should beware, though, the electorate might see through this quite quickly once the taxes begin to bite.
The nuclear industry will benefit. No-one wants to live next to a nuclear power station but some governments have already started removing steps from the planning negotiation process to speed up their deployment.
Global Cooling will be a more serious problem than Global Warming. We should start planning now how we are going to decommission those new nuclear power stations when they are under a mile of ice.

Oh God,yes The Wall Street Journal and the American Enterprise Institute are going to save us. Why cannot we have similar institutions in UK? I know where to turn, General Motors! We are all going to be saved by reading Ayn Rand. Although this might be painful, we must do it. Now that righteousness has defeated communism, we must defeat the socialists who would direct our attention at melting ice. Polar bears, penguins and Eskimos are the enemies. Margaret Thatcher has led the way My hands are cracked with all the hand wringing, about the Stern Report. it’s awful but my pain is assuaged by watching Nigella Eats and thinking about her loving father who will slay the evil Stern, the yellow Kyoto hoard and the IPPC. We aren’t going to die because W, Dick Cheney, Haliburton (again, where are our big UK firms when we need them?) and God will save the Earth and tax subsidies for big, really big Agriculture. We are gonna fight organic gardening and win! UFOs are nothing compared to the Pigovian AntiChrist. The Enfield sector?

@Richard Let’s take you a bit at a time. “Next time someone insists global warming IS happening, ask yourself where their views come from – and whose interests they serve. Let’s see if we can find some beneficiaries … Well, the environmentalists will benefit. They will gain more supporters and have more influence.”
Interesting logic… Anybody who believes anything will gain more supporters and influence if they happen to be right! So they must be wrong.
“Big business will benefit. Many have thousands of employees who will now all be trying to save energy and hence reduce the company’s energy costs.”
Is this not to everybody’s advantage, anyway? Who gains if energy is wasted? However, companies will have to invest to save, so it is not at all clear that saving energy will be saving money, at least in the short to medium term.
Again, all things which are useful even if there were no climate change. They will be needed as the finite resources of oil and gas become depleted and more expensive.
“Oil companies will benefit. Yes, they will sell less oil but they should be able to sell it at a much higher price. So with less work they will make more profit and the oil will last much longer.”
A reduction in demand will lead to higher prices? Aren’t you confusing with Peak Oil which will cause a reduction in supply?
“Advisors to governments and big business on Climate Change will obviously benefit. As will people who give talks on Climate Change to invited audiences.”
An argument you can apply to anyone promoting any viewpoint, including your own.
“Anyone smart enough to see a business opportunity in the trading of carbon credits will quickly become a multi-millionaire. The business requires no manufacturing effort or stock, only a modest amount of office staff and, all being well, governments will make it compulsory thus maximising revenue. Only a very small “rake off” will generate millions. (Anyone spring to mind?)”
You can apply the same argument to any kind of financial trading. If it’s so easy there should be plenty of competition. I suggest you do it yourself
“Governments will benefit. They have been trying to find a popular tax for years. This could be the opportunity they have been waiting for. They should beware, though, the electorate might see through this quite quickly once the taxes begin to bite.”
If you think “green” taxes are popular I think we must live in a different universe. However, if they were I’d see this popularity as a benefit. Taxes (you can argue on the level) are an unpopular necessity. For them to be more readily accepted would be good.
“The nuclear industry will benefit. No-one wants to live next to a nuclear power station but some governments have already started removing steps from the planning negotiation process to speed up their deployment.”
The nuclear industry will probably benefit. But none of this, or indeed any of the above arguments have the slightest relevance to the issue, which is: - Is global warming occuring? - If so, – to what extent? – what are the implications of this? These are matters of fact, totally uninfluenced by anyone’s opinions or ulterior motives.
“Global Cooling will be a more serious problem than Global Warming. We should start planning now how we are going to decommission those new nuclear power stations when they are under a mile of ice.”
Whatever. Why should anyone take the slightest notice of a bald assertion made with absurd imagery and without a shred of supporting evidence? Lynas has set out the views of the experts working in the field. The conclusions of these experts are accepted by the scientific academies of every major country. This does not mean they are necessarily right
- 100-1 shots have been known to win horse races, and scientific method doesn’t do absolute certainty -but it’s pretty clear where the balance of probability lies, and it isn’t with the politically-motivated stance of some think tank with an axe to grind.Richard

“sceptics are supported by politically powerful conservative think tanks funded by wealthy foundations and corporations”
Perhaps many “sceptics” are actually supported by the fact that there is now no observational evidence that global warming is caused by carbon emissions.
If you know of any references that point to causality rather than just correlation please direct me to them.

OK Mark.
So you must be the fellow who has the evidence that industrial-CO2 is bad for the environment. Otherwise you wouldn’t be talking in this arrogant fashion right?
But I know for a fact that you don’t have this evidence. Since all extant evidence attests to the fact that industrial-CO2 is good for the environment.
Admit you are wrong.

With anything in life it’s always easier to deny a problem or issue, to bury your head and pretend it will go away. I remember Sting going to the Amazon in the mid 80’s to campaign for the indigenous tribes and the rainforest, he was widely laughed at in the media and by his peers. Right now tackling climate change or even admitting it is a problem with all it’s knock on effects is just too big an issue for many people to contemplate, too risky for many political leaders and too “inconvenient” for the rest of us. The reality is we need strong political leadership (Gordon Brown is not the man) to put more pressure on industry, the big polluter. At the same time we need to find a way to help people in their own homes and lives feel that they can make a difference. As Schwarzenegger has said we have to get young people to think it’s cool to get them involved. I dont have the answers but i do know without change in leadership and social attitudes towards the environment there is no hope! Never campaigning for money and medicine for Africa or third world debt, do them all a favour and campaign to save their eco-systems. That will help them feed themselves and the rest of the world as well. Funny but I dont hear U2 or Coldplay or Jay-Z campaigning like Sting did. Maybe they just want the fame, the money and to ease their social consciences when the cause is championed by the media, so they can make even more money!

The end is nigh… for climate alarmists like you Mark. I hope in years to come, when the only source of global warming emanates from the red faces of those who’ve bought your opportunistic, hypocritical calp-trap, someone cools your face with the application of an ice cream pie.
Do unto others and all…
It’s like a slow-motion car wreck seeing all this crumble, I used to think that in five years the pubic and those with traditional scientific method would put paid to this brand of medieval scaremongering (and its attendant financial rewards) but now that the cooling contradicts the computer models (didn’t see that, pal) I give it 18 months.
And I’ll be back on here to gloat when it all falls apart – in the eyes of the public and the deliberations of those in the west who make policy, when faced with electoral oblivion and mounting empirical data.

It feels like we ought to be preparing practically and mentally for going through this in the least painful way possible, even if we would be facing human extinction.
On a practical level this would be preparing self-reliant small societies, where one could live independently from surrouning infrastructure. A great deal of mental/spiritual preparation would also be needed in order to reduce the pain for oneself and others.

Mark, If skeptic commentary can be linked to think tanks, what about the publicly promoted linkage between alarmist communication/methods and the PR strategies paid for by governments? Strategies such as created by IPPR (“Warm Words”) etc.
You have no concern about masking real scientific discourse behind a facade of agreement?
The science is far less settled than you imagine. (BTW, I’m not a denialist, just someone who wants to see the truth. Including admissions of “we don’t really know” when that’s the case. It disturbs me greatly that the IPCC adjusted the scientific result (1/2 of all conclusions were considered by scientists to be least-confident in the final scientifically-reviewed version) in a very biased way (NO conclusions were considered least-confident in the final summary for policymakers.)

Amazing, isn’t it. Mark Lynas tells us that if someone slightly disagrees with his extreme views on global warming then they are funded by nasty american think tanks so you should ask them who benefits from their viewpoint. he also says that himself having no scientific qualifications makes him idea to explain science to others who also have no science qualifications.
But Mark is an ‘activist’ so where is he coming from. How can you be even handed and accurate and an activist. Which direction does an ‘activist’ with no science qualifications come from?
He would say that wouldn’t he…and by the way. The truth is that the world has been cooling for ten years – no getting away from it. Please provide the reference in the IPCC reports that said that.

I am neither owned by a large multinational corporation nor do I work for the oil industry. I state that because no doubt someone will accuse me of just that.
I am however an astronomer and take a keen interest in what’s going on elsewhere in the solar system.
Our Sun is a G-Type variable star – basically it varies in its luminosity and energy output. Why is that important? Well at 96 million miles distance its very important. Imagine your sat in front of a four bar fire with two bars lit. Light another and you will stand farther back or you will burn.
Well our sun has being acting funny recently. Sunspot output has been increasing for the past 100-150 years and infact solar cycles 21-23 have seen the largest 11 year solar maximum for the past 8,000 years. We just need to look back to the maunder minimum (attributed to being around during the little ice age) to realise theres an important factor here.
Interestingly the sun went into a funny phase about two years ago and we are entering an extended period of solar mimima. Now long minima are not unknown, however should the 24th cycle remain low, then you guys will notice (allegidly) cooling over the next several years. Believe me global cooling is a far bigger problem.
Interestingly, global warming has been noticed on Mars and Jupiter – with Earth warming, is this coincidental.
I am not saying we should abandon plans to look after earth and clean up, but sometimes it concerns me when scientists and the g.warming community attack others for remaining doubtful.
Most interglacials last approx 10,000 +/- a few thousand years. Noticable there are always huge CO2 increases before (and just before) the interglacials end.
With the sun going odd on us, with a warming trend and the present interglacial now approaching 12,000 years old, it does make one wonder what’s really going on?
Incidentally, the antarctic ice sheet has expanded to its greatest recorded extent over the past few years – contradicting the arctic melt – somethingodd there.
I dont say global warming is not happening but just how mich is hype and how worried should we be about its evil twin – global cooling?

I was neutral in the AGW debate until I was given a copy “High Tide”. The I did some checking and found that some of your arguments were flawed:- World glaciers started retreating BEFORE the days when fossil fuels were in general use, thus glacier melting can not be the result of increased CO2. Also the seas are not rising any faster than they have done for centuries. The sea around Tuvalu has not risen by the amount you imply. Tide readings in the area confirm this. Satellite and balloon temperature readings agree that the world temperature has not increased for ten years despite rising CO2.(2ppm annually). Does this not suggest that some other agency than CO2 has caused much of 20th Century warming? Argo buoys show that the Pacific Ocean has now cooled (slightly), no climate computer model forecast this, and it is probable that the PDO has moved into a cold phase that will bring about Global COOLING for the foreseeable future. Does this not suggest to you that CO2 is but a small player in the forces that change world temperature? Recent reliable, scientific papers suggest that CO2 is responsible for a tiny fraction (about 30%) of the world warming during the last century, i.e. 30% of 0.6C. The IPCC themselves estimated (in AR4) that when CO2 reached today’s level of 385 ppm, temperature would have risen by between one degreeC and two and a third degreesC, say a median figure of one and two third degrees (1.66C) however the actual rise is only 0.6C . The IPCC computer programmes seem to have got warming wrong; too high, by a factor two or three. This suggests the new research is right, and that to date CO2 is responsible for no more than about one fifth of a degreeC. This is tiny and may even be beneficial. We will be glad of this when Global Cooling caused by the Pacific Ocean kicks in! A due regard for science seems to be missing from your writing, perhaps you should have spent more time at KB than the Old Quad!!

when humans began the change from hunter gathers to agrarians some 15,000 years or so years ago, in earnest, the CO2 dynamic was tipped.
