Global temperature rises of 4°C could see new 55°C ‘super heatwaves’ hit densely populated areas all over the world every year.
That is according to research by the European Commission’s Joint research centre, which shows that coastal China, the US east coast, and large parts of India and South America would be hardest hit.
Projections from the University of Washington in the US show a 90% chance of global warming between 2° and 4.9°C during this century.
