Monbiot: Bush's Climate Change solution is denial in disguise

Don't be fooled by Bush's defection: his cures are another form of denial

The president's avowed conversion on climate change is illusory. He is just drumming up new business for his chums.

George Bush proposes to deal with climate change by means of smoke and mirrors. So what's new? Only that it is no longer just a metaphor. After six years of obfuscation and denial, the US now insists that we find ways to block some of the sunlight reaching the earth. This means launching either mirrors or clouds of small particles into the atmosphere.

The demand appears in a recent US memo to the Intergovernmental Panel on Climate Change. It describes "modifying solar radiance" as "important insurance" against the threat of climate change. A more accurate description might be important insurance against the need to cut emissions.

Every scheme that could give us a chance of preventing runaway climate change should be considered on its merits. But the proposals for building a global parasol don't have very many. A group of nuclear weapons scientists at the Lawrence Livermore laboratory in California, apparently bored of experimenting with only one kind of mass death, have proposed launching into the atmosphere a million tonnes of tiny aluminium balloons, filled with hydrogen, every year. One unfortunate side-effect would be to eliminate the ozone layer.

Another proposal, from a scientist at the National Centre for Atmospheric Research, in Boulder, Colorado, suggests spraying billions of tonnes of sea-water into the air. Regrettably, the production of small salt particles, while generating obscuring mists, could cause droughts in the countries downwind. Another scheme would inject sulphate particles into the stratosphere. It is perhaps less dangerous than the others, but still carries a risk of causing changes in rainfall patterns. As for flipping a giant mirror into orbit, the necessary technologies are probably a century away. All these fixes appear more expensive than cutting the amount of energy we consume. None reduces the concentration of carbon dioxide in the atmosphere, which threatens to acidify the oceans, with grave consequences for the food chain.

The demand that money and research be diverted into these quixotic solutions is another indication that Bush's avowed conversion to the cause of cutting emissions is illusory. He is simply drumming up new business for his chums. In his state of the union address last week, he spoke of "the serious challenge of global climate change" and announced that he was raising the government's mandatory target for alternative transport fuels fivefold. This is wonderful news for the grain barons of the red states, who will grow the maize and rapeseed that will be turned into biofuel. It's a catastrophe for everyone else.

An analysis published last year by the Sarasin Bank found that until a new generation of vegetable fuels, made from straw or wood, is developed, "the present limit for the environmentally and socially responsible use of biofuels [is] roughly 5% of current petrol and diesel consumption in the EU and US". Bush now proposes to raise the proportion to 24% by 2017. Already, though the rich world has replaced just a fraction of 1% of its transport fuels, the UN Food and Agriculture Organisation reports that using crops to feed cars has raised world food prices, with serious consequences for the poor. Biofuels fall into the same category as atmospheric smoke and mirrors - a means of avoiding difficult decisions.

But at least, or so we are told, the argument over whether or not manmade climate change is happening is now over. On Friday the Intergovernmental Panel on Climate Change publishes the first installment of its vast report, which collates the findings of the world's climate scientists. Though conservative in its assumptions, it shows that if you persist in believing that there is no cause for concern, you must have buried your head till only your toes are showing. If even Bush now grudgingly acknowledges that there's a problem, surely we've seen the last of the cranks and charlatans who had managed to grab so much attention with their claims that global warming wasn't happening?
