Greenland experienced an “enhanced melt” from July 15 to 17, which resulted in the loss of enough ice cover to fill 7.2 million Olympic-size swimming pools.
The dramatic event is captured in a satellite image that shows how 18 billion tons of water runoff completely change the landscape.
The European Union’s Copernicus satellite captured a climate-change-driven landscape showing areas of turquoise and varying shades of blue, meltwater running down the surface of bedrock that should be white because it’s usually frozen.
Although there have been many melting events in previous years, the latest melt is twice the usual and experts warn that it has made a significant contribution to global sea level rise.
The melting of the Greenland ice sheet has contributed to sea levels rising by about half an inch over the past 30 years, but if the 695,000-square-mile structure melts completely, levels will rise by 20 feet, flooding many of the world’s coasts.
Much of the melting was caused by warm air from the Canadian Arctic archipelago, said Ted Champos, senior scientist at the University of Colorado’s Geoscience and Observation Center and the National Snow and Ice Data Center (NSIDC).
The Canadian Arctic archipelago is located north of the Canadian mainland, which has also been hit by a heat wave that has raised temperatures to more than 60 degrees Fahrenheit.
However, warm winds accompanied the high pressure dome over Greenland, resulting in calm winds and sunny skies, resulting in higher temperatures.
According to Weather and Climate: “In July, the average daily maximum temperature is cool and ranges from 6°C (43°F) at Cap Tobin to 10°C (50°F) at Engmagsalek. Nighttime temperatures are usually lower. down to 2°C (36°F) in English and 0°C (32°F) in Cap-Tobin. This is one of the warmest months of the year.”
The Greenland ice sheet is the second largest mass of freshwater ice on the planet, second only to Antarctica.
And the Arctic is warming rapidly due to climate change. The latest data for April shows that this region could be warming four times faster than any other region in the world.
The melting of the Greenland ice sheet began in 1990 and has accelerated since 2000.
On July 27, 2021, Marco Tedesco, a climatologist at Columbia University, reported that the Greenland ice sheet lost 8.5 billion tons of surface mass in one day, enough to cover Florida with two inches of water.
And researchers at the Center for Polar and Marine Research found that the ice sheet lost a total of 532 gigatonnes of mass.
