>>The worst feared early tipping point has already started happening. From Youtuber, "justhavathink," reporting on one of the most recently released peer-reviewed studies, the Arctic has switched from a carbon sink to a carbon source. <<
Ah, sounds like more of the permafrost is melting than has been reported. :/
>>After 27 years in newsrooms, I thought I was hardened to ugly news, I worked in Hobart when the Port Arthur Massacre happened. The arctic flip story cost me some serious sleep last night.<<
I do worry about the Arctic, not just its carbon dynamics, but the sea ice. The more navigable the Northwest Passage gets, the worse the political risk gets because people will fight over it. Again.
My main worry is the thermohaline cycle though. It's already wobbling, so I don't think it's going to last a great deal longer, which is a real disaster. Also, the worse the Arctic situation gets, the more it feeds into that, because melting ice is what's most likely to break it.
Ironically, the March 1 Poetry Fishbowl will be on "Yes Actually It IS That Bad" so feel free to prompt for the Arctic or other climate change issues then.
