Climate change: Ed Davey on science and energy policies

The "vast majority" of climate change scientists believe climate change was happening, and man-made activity was causing it, said the energy secretary.
Ed Davey said "we should always challenge the science", but only a "tiny number" thought it was not happening.
He called for more balance in the debate, as he spoke to Andrew Neil about government policies over climate change, global warming claims and renewable energy.
And the Liberal Democrat rejected figures that an annual £112 increase on UK fuel bills was down to climate change policies, saying the bulk of that was down to tackling fuel poverty and making homes warmer.
