Greenland ice sheet is melting faster than originally thought

The Greenland ice sheet is melting faster than originally thought.

The melting is dumping even more water and ice into the ocean than was expected.

The bottom of the ice sheet is releasing meltwater.

In both 2012 and 2019, mass melting events occurred in both June and July, due to cloud cover and high temperatures.

While the Antarctic ice sheet is the largest ice sheet in the world, Greenland is the second largest. It is also the largest contributor to global sea-level rise.

If the entire 2,850,000 cubic kilometres of ice in Greenland were to melt, it would lead to a global sea-level rise of 7.2 metres.
