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, and more than three-quarters of that acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

Like weather and climate, there are two factors in sea level rise: year-to-year small rises and falls that are caused by natural events and larger long-term rising trends that are linked to man-made climate change.

Global sea levels were stable for about 3,000 years until the 20th century when they rose and then accelerated due to global warming caused by the burning of coal, oil and natural gas.

Greenland has caused three times more sea level rise than Antarctica so far, but ice melt on the southern continent is responsible for more of the acceleration.
