“Earth is certain to have a baked-crust runaway greenhouse. It will destroy all life on Earth, but it is nothing to worry about. ... The runaway that we should be concerned about is the existential threat (ET) runaway.” The great @DrJamesEHansen. mailchi.mp/caa/sophies-pl…
“ET runaway will occur if we let high fossil fuel emissions continue to the point that rapid disintegration of the Antarctic and Greenland ice sheets begins, with sea level rise of many meters and loss of all coastal cities.”
“At the same time, low latitudes would become unreasonably hot and humid. Global emigration pressures would become so great that global governance breaks down. Chaos ensues.“
“I am optimistic that we can avoid the ET runaway greenhouse,” Hansen writes. “I believe the United States and China will realize that we are all in the same boat. We can, together, use our technological prowess to pull back from the brink.” But...
“Pulling back from the brink will not happen without effort. It is not enough to demand that governments address the global climate change matter. None of the political parties are advocating an approach that would actually work.”
