Today's UN report on climate change is a "stark warning" about the need to reduce carbon emissions, Energy Secretary Ed Davey has told Sky News' Murnaghan programme.
The Liberal Democrat MP also said the decreasing cost of renewable energy meant decarbonising need not be overly expensive.
I agree we should be doing absolutely everything. This is a stark warning that the world is looking down the precipice if we don’t take action now. But it also says - and some good news - is that the cost of renewables, things like solar and wind, are coming down, so we can go green in an affordable way.
