Someone should contact Neil Young and tell him to stop making albums about electric cars and start writing songs about the Amazon. While I write this in jest, the boringness of someone pulling your ear about the devastation of deforestation should still be as important as talking about topics such as the duel between San Francisco and Portland for electric car supremacy.

Forty percent or more of the Amazon rainforest will be “decimated” by the middle of the next century even if we cut all CO2 emissions by 2050, said the UK Met Office. The finding was presented this past month in Copenhagen, which is preparing to host the UN Climate Change Conference in December.

The damage will be so severe that it will cause irreversible changes to the world’s weather patterns, which is expected to bring more storms, floods and heat waves to Britain. Up to 40 per cent of the rainforest will be lost if temperature rises are restricted to 2C, which most climatologists regard as the least that can be expected by 2050.
