more tipping points

An average global temperature rise of 7.2F (4C), considered a dangerous tipping point, could happen by 2060, causing droughts around the world, sea level rises and the collapse of important ecosystems.

The Arctic could see an increase in temperatures of 28.8F (16C), while parts of sub Saharan Africa and North America would be devastated by an increase in temperature of up to 18F (10C).

Britain’s temperature would rise by the average 7.2F (4C) which would mean Mediterranean summers and an extended growing season for new crops like olives, vines and apricots.

However deaths from heat waves will increase, droughts and floods would become more common, diseases like malaria may spread to Britain and climate change refugees from across the world are likely to head to the country.

Dr Richard Betts, Head of Climate Impacts at the Met Office Hadley Centre, said the new study showed how important it was to try and reduce emissions.
