Warming is accelerating sea level rise as Greenland and Antarctic ice sheets melt
Melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of sea level rise, new satellite research shows.
At the current rate, the world’s oceans on average will be at least 2 feet (61 cm) higher by the end of the century compared to today, according to researchers who published in Monday’s Proceedings of the National Academies of Sciences.
Sea level rise is caused by warming of the ocean and melting from glaciers and ice sheets. The research, based on 25 years of satellite data, shows that pace has quickened, mainly from the melting of massive ice sheets.
Of the 3 inches (7.5 cm) of sea level rise in the past quarter century, about 55 percent is from warmer water expanding, and the rest is from melting ice.
But the process is accelerating…
