Tim Yeo has issued a statement "clarifying" his views on climate change:
In the light of what has appeared on the Telegraph website suggesting that I have changed my views about climate change, I wanted to make clear that this is not the case.
My views have remained the same for over two decades. I accept the overwhelming scientific evidence that human activities are having a major impact on the climate – there is an overwhelming probability that the impact of greenhouse gas emissions from human actions are contributing to climate change.
I will continue to press for urgent action on this matter, making the case that the move to a low carbon economy is not just right environmentally but also in our economic interest.
Meanwhile the Telegraph has released its audio recording of what Yeo said (here). His remarks do seem to me to represent a toning down of his position, but it's possible that we are over-interpreting.
