Ice melt, sea level rise and superstorms: evidence from paleoclimate data, climate modeling, and modern observations that 2 °C global warming could be dangerous
We hypothesize that ice mass loss from the most vulnerable ice, sufficient to raise sea level several meters, is better approx- imated as exponential than by a more linear response. Dou- bling times of 10, 20 or 40 years yield multi-meter sea level rise in about 50, 100 or 200 years.
