The Greenland ice sheet lost a record amount of ice in 2019, equivalent to a million tonnes per minute across the year.
Satellite data shows that the climate crisis is heating the Arctic at double the rate in lower latitudes, and the ice cap is the biggest single contributor to sea level rise, which already imperils coasts around the world.
The ice sheet shrank by 532bn tonnes last year as its surface melted and glaciers fell into the ocean. These could have filled seven Olympic-sized swimming pools per second.
Snowfall in Greenland was low in 2019, also due to the blocking pattern, meaning relatively little new ice was added. If the entire Greenland ice sheet melts, sea level would rise by six metres.
But despite the rapid melting, the Greenland ice sheet isn’t necessarily doomed to melt entirely. First, as glaciers retreat they lose contact with warmer ocean waters and therefore melt less. Secondly, the melting of the sheet with warm air takes centuries, during which time we might be able to reverse the rise in global temperature.
If this situation continues , the whole ice in the country may melt and lead to many disasters. Many climate activists are trying to stop this. And explaining the people about the problems caused by ice melting.
