London, August 7 : A scientist has suggested that the world should be prepared to face an alarming increase of 4 degree Celsius in global temperatures.
A report in The Guardian said that this was suggested by agriculture and coastal erosion Professor Bob Watson, who is one of the UK government’s chief scientific advisers.
In policy areas such as flood protection, UK should plan for the effects of a 4C global average rise on pre-industrial levels, said Watson.
Globally, a 4C temperature rise would have a catastrophic impact.
According to the government’s 2006 Stern review on the economics of climate change, between 7 million and 300 million more people would be affected by coastal flooding each year.
