Earth on verge of five catastrophic climate tipping points, scientists warn
“Tipping points in the Earth system pose threats of a magnitude never faced by humanity,”
Tim Lenton, from the University of Exeter’s Global Systems Institute.
"They can trigger devastating domino effects, including the loss of whole ecosystems and capacity to grow staple crops, with societal impacts including mass displacement, political instability and financial collapse. The tipping points at risk include the collapse of big ice sheets in Greenland and the West Antarctic, the widespread thawing of permafrost, the death of coral reefs in warm waters, and the collapse of atmospheric circulation in the North Atlantic."
