UK faces a "catastrophe" of floods, droughts and killer heatwaves

The UK faces a "catastrophe" of floods, droughts and killer heatwaves if world leaders fail to agree a deal on climate change, the prime minister will warn.

Gordon Brown is to address the Major Economies Forum in London, which brings together 17 of the world's biggest greenhouse gas-emitting countries.

Mr Brown will say there will be "no plan B" if agreement is not reached at December's UN summit in Copenhagen.

Negotiators have 50 days to save the world from global warming, he will add. -bbc
