The formation of a new “supercontinent” could wipe out humans and all other mammals still alive in 250 million years, researchers have predicted.
Using the first-ever supercomputer climate models of the distant future, scientists from the University of Bristol in the United Kingdom predicted how climate extremes would intensify after the world’s continents merge to form one supercontinent, Pangea Ultima, in around 250 million years. They found it would be extremely hot, dry and virtually uninhabitable for humans and mammals, who are not evolved to cope with prolonged exposure to excessive heat.
While there are large uncertainties when making predictions so far into the future, the scientists said that the picture appears “very bleak,” with only around 8% to 16% of land on the supercontinent habitable for mammals.
