Ice Dynamics

Several of the articles below point to faster changes observed in glaciers and ice sheets than models allowed for. That is, ice models need to be improved to account better for the processes identified. The upshot is that ice loss generally occurs faster that models projected. This implies that sea level, during this century, will rise faster than some projections.

Cold icemelt from Antarctica spreads out along the ocean surface. That prevents the vertical mixing (warmer water to the top) there that has driven the great ocean circulation. In Antarctica, the warmer water below the ice eats away at placiers from underneath. Cold icemelt from Greenland leads to shutdown of the Atlantic overturning circulation.
Ice losses from Greenland and Antartica grow, modelled as exponentially, with doubling times of 10, 20, or 40 years. Sea level rises non-linearly, 5-9 meters over 50 to 150 years. This is simlar to what happened 120,000 years ago, when sea levels rose from 3-4 meters higher than today to about 9 meters higher, including 2-3 meters within several decades. (For perspective, the sea level range (maximum - minimum) over the recent ice ages was about 125 meters.)
