Planet ‘must race to prevent 2C global temperature rise’

THE planet faces irreversible climate change if drastic action is not taken to prevent an increase in temperature of 2C.

Environmental campaigner George Monbiot says a chain reaction could be set off if the temperature rose by that much.

“This is the critical level we have to try and prevent if we are to stop the worst effects of climate change,” said Mr Monbiot, who is also a columnist for British newspaper The Guardian.
