Had I any such expectation of longevity I’d bet against it because indications are that the ice pack survived in a reduced state during the Holocene Thermal Maximum when temperatures were 2-4°C warmer. While the good professor makes a case for enhanced greenhouse (in the Arctic) I think cloud cover and albedo far more important and that the ice will largely survive. Nonetheless, LuMo is always interesting:
CO₂ and ice-free Arctic Summer 2100
In recent 3 days, Andrew Revkin has pleased many climate skeptics by his opinions about the Arctic climate and ecosystems:
On Arctic Ice and Warmth, Past and Future
A Debate on Death Spirals and Arctic Resilience
Building on many recent papers that showed significant variations in the Arctic climate in the past (safely exceeding the recent changes), Revkin decided that there’s no reason to be afraid of the Arctic ecosystems because they have survived similar or more dramatic changes in the past. I agree.
Nevertheless, I am probably going to repay debt to Revkin, shock some skeptics, and please by alarmists by this following opinion of mine: (The Reference Frame)
