Dear Alan,
It is not only melting of sea ice and permafrost that needs to be highlighted. Today's Temperature Legend Map from Foreca shows that Ilulissat Ice Fjord that drains 7% of Greenland ice sheet bathin on top temperatures today between +20-25C. This is substantial heat on the glacier, the morning temperatures shown are littel more moderate. Last time I saw these kind of temperatures +24C in Ellesmere Island, the Aylers Ice Shelf collapsed on that particular week. The heat and warm water does damage ice considerably and I expect that Greenland's temperatures are much like the Baffin Island's once Arctic Ocean's sea ice is gone. I think today's weather is a good indicator what shall become. I am increasingly concerned that tempeartures at around +24C, can't be tamed by sulphur dioxide or other means, it just could be a magnitude or several times more than the negative feedback induced by the geoengineering methods. I fear the not enough scenario. I don't want to be devil's advocate, but weather's could rise too high and out of control. Let's hope this peak heat stays short, but I would not be surprised if glaciers speed up once again.
