Don't Be Fooled By Bush's Defection: His Cures Are Another Form Of Denial

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. http://www.commondreams.org/views07/0130-27.htm
