Does anyone know of the implications of a year-round ice-free artic? Is the artic salvageable at this point? It seems evident that soon the artic will have a short period of being ice-free, kickstarting an inexorable process with yet longer periods of being ice-free.

It is safe to assume at this point climate change is like an asteroid on a trajectory of near term collision with Earth. I'd rather be wrong and alive then right and extinct on this one. But thats me.
