" Asked on Tuesday night whether it was better to take action to mitigate the effects of climate change than to prevent it in the first place, he said: “The first thing to say is it does not represent any threat to the survival of the planet. None at all. The planet has survived much bigger changes than any climate change that is happening now. He went on: “Although I think the evidence that the climate is changing is now overwhelming, the causes are not absolutely clear. There could be natural causes, natural phases that are taking place.”
