Increasing production of biofuels to combat climate change will release between two and nine times more carbon gases over the next 30 years than fossil fuels, according to the first comprehensive analysis of emissions from biofuels in today's Guardian Unlimited.
The original work is in Nature, so its hard to read unless you subcribe. But the reserchers make the point that clearing forests for biofuel production dramatically increases the amount of carbon in trees and soil which is available to the atmosphere.
The article concludes with
The researchers say the emphasis should be placed on increasing the efficiency of fossil fuel use and moving to carbon-free alternatives such as renewable energy.
Argue with that and stay fashionable.
