Global warming may have already passed irreversible tipping point

After the biggest-ever expedition to the Arctic, scientists warn point of no return on global warming may have already been reached.

Global warning may have already passed an irreversible tipping point, the scientist who led the biggest-ever expedition to the Arctic has warned. Presenting the first findings of the world’s largest mission to the North Pole, an expedition involving 300 scientists from 20 countries, Markus Rex said on Tuesday that the researchers had found that Arctic ice is retreating faster than ever before. “The disappearance of summer sea ice in the Arctic is one of the first landmines in this minefield, one of the tipping points that we set off first when we push warming too far,” he said during the presentation in Germany’s capital, Berlin.
