A new Mori opinion poll has found that the public suspects that the negative effects of global warming predicted by scientists are being exaggerated. Fifty six per cent of respondents also said they think that the scientific community is split down the middle over whether or not climate change is real. So as a nation we're still officially 'sceptical' about climate change. Or are we? Greenpeace director John Sauven has his doubts.

Last month we launched a campaign for rigorous controls on biofuels because while biofuels could make a small contribution in the battle against climate change, it could in fact do more harm than good.

If rainforests are cut down to make way to grow 'green fuels', it will not only destroy homes for animals like the orang-utans, it will also be catastrophic for the climate releasing more greenhouse gases by destroying forests than we will save using biofuels.

To tackle climate change we need to take action on every level - big, bold action that changes the way our cities use energy, and simple small actions we can each take that will all add up to big energy savings.
