The Energy Collective | NATURE: Sea level rise may exceed worst expectations

A brand new paper released in Nature suggests that the polar ice sheets are more vulnerable to global warming than previously feared. 2 degrees Celsius of global warming could commit us to 6-9 meters (20-30 feet) of long-term sea level rise. The study is based an extensive database of geological indicators for the last interglacial period, roughly 125,000 years ago, when polar temperatures were about 3-5 degrees Celsius warmer than today, as is expected if global warming hits 2-3 degrees Celsius above pre-industrial levels. The findings reinforce that the developed world needs to be prepared to fund significant adaptation support, particularly for low-lying countries such as Bangladesh.
