Greenland lost 532 billion tonnes of ice in the past year.
It has set records and raised alarms about accelerating sea-level rise.
Losing the ice sheet is equivalent to an additional three million tonnes of water flowing into the global oceans every day.
Cracking glaciers and melting jets of water split open blocks of ice two to three kilometers thick in Greenland.
This then makes the number of global sea-level rise the largest in 2019.
According to scientists reporting in the journal Communications Earth & Environment, last year’s mass loss was at least 15 percent above the previous record in 2012.
But experts say what’s more worrying are the long-term impacts.
If all of Greenland’s ice sheet melted, it would raise global oceans by seven meters.
Even a modest rise of a few meters would change the world’s coastlines.
Not only that, but it also makes the land that is inhabited by hundreds of millions of people today uninhabitable.
Until the 2000 period, Greenland’s ice sheet generally accumulated as much mass as it was releasing.
However, over the past two decades, the increasing rate of global warming has upset this balance.
Changing weather patterns due to climate change has also resulted in fewer clouds and less snow.
This high-pressure system also results in sunny days with warmer temperatures and that accelerates the loss of the ice sheet.
