The UK should take active steps to prepare for dangerous climate change of perhaps 4C according to one of the government’s chief scientific advisers.

In policy areas such as flood protection, agriculture and coastal erosion Professor Bob Watson said the country should plan for the effects of a 4C global average rise on pre-industrial levels. The EU is committed to limiting emissions globally so that temperatures do not rise more than 2C.

“There is no doubt that we should aim to limit changes in the global mean surface temperature to 2C above pre-industrial,” Watson, the chief scientific adviser to the Department for the Environment, Food and Rural Affairs, told the Guardian. “But given this is an ambitious target, and we don’t know in detail how to limit greenhouse gas emissions to realise a 2 degree target, we should be prepared to adapt to 4C.”
