Greenland is in danger of collapse due to global warming, the child of climate change. The extreme heatwave that hit Europe in mid-July tastes like it caused catastrophic damage, perhaps irreversible, to the already compromised and complex Greenlandic biome.
Accordind US National Snow and Ice Data Center, between 15 and 17 July the glaciers present in the northwestern area of the island lost 6 billion tons of water every day, an amount that could cover with more than 30 centimeters of water the entire state of West Virginia.
Greenland will continue to melt regardless of what happens with climate change. According to expert estimates, since 1985 the largest glaciers in Greenland have retreated by an average of 3 kilometers, and since the beginning of the new millennium an average of 450 billion tons of ice have melted.
Greenland lost 6 billion tons of water from glaciers in 3 days
On Tuesday 27 July 2021 alone, the Greenland ice sheet lost 8.5 billion tons of surface mass. In 2019, the total loss reached 590 billion tons of ice. Given that it contributed to the sea level rise of 1.5 millimeters.
The temperatures in Greenland these days have touched 15.5 ° C, accelerating the melting of the ice, with a significant impact on sea level rise. If all of Greenland's glaciers were to melt, the sea level would rise by 7.5 meters, according to scientists.
It is believed that fresh water from the island's melting ice and exceptional rainfall could even alter the North Atlantic Current, known as the Gulf Stream. Ted Scambos, a glaciologist at the University of Colorado and the NSIDC, said: "Northern melt this past week is not normal considering the climatic averages of the last 30 to 40 years.
Melt is increasing and this event has represented a peak. " Kutalmis Saylam, a researcher at the University of Texas, added: "It definitely worries me. We were able to wander around in our t-shirts, it wasn't really expected."
