I've been away a while), I don't think global warming, or, to put it the correct way, the involvement of human activity in accelerating and/or augmenting global warming is a hoax. I found the article interesting and agree with the writer because politics is playing a much bigger role, in such measures as increasing the use of biofuels, than sound strategies based on evidence, scientific or otherwise.There's a problem developing now with consumers here in the UK purchasing produce that appears to have travelled the least distance. This, however, is putting producers in poorer countries at a disadvantage. Also, it does not have any real impact on "carbon footprint", or however you care to describe it, because producers in the UK tend to have to use far more energy to grow out of season crops than that used to grow and transport the produce from, say, an African country.
Ignorance and political manoeuvring are taking the place of coordinated planning based on the best evidence available. No matter whether you think human involvement in global warming is proven or not, this is worrying.
