Greenland suffers a heat wave with temperatures more than ten degrees above the usual values for this time of year. Experts warn that this sudden increase in temperatures is causing a “massive” thaw of the Arctic ice sheet .
Floods, fires and extreme weather: climate chaos was this
Records indicate that, since at least last Wednesday, the ice sheet covering the vast Arctic land is losing approximately 8 billion tons every day . This is twice the average rate expected during the summer , according to data from the Polar Portal, a modeling tool run by Danish research institutes.
In recent days, unusual temperatures of more than 20 degrees have also been registered with local records in northern Greenland, according to the Danish meteorological institute DMI. At the small Nerlerit Inaat airport, in the northeast of the country, this Thursday the thermometer reached 23.4 degrees Celsius. This is the highest record recorded since the meteorological station became operational.
The advance of this heat wave is also accelerating the Arctic thaw . According to a report from the Polar Portal, an expert in monitoring this phenomenon, “the immense volume of molten water released daily in recent days would be enough to cover the entire surface of Florida with five centimeters of water .”
The last refuge of Arctic ice is more vulnerable than we thought
Of particular concern is the impact of the thaw on Greenland, which accumulates almost 1.8 million square kilometers of frozen soil. The records corroborate that, as global warming progresses, the Arctic is warming up to three times faster than in other parts of the world.
It is also worrisome that, according to several scientific studies, the Arctic thaw accelerates the rise in sea levels. The Greenland thaw, by itself, would have enough force to raise the level of the oceans by six to seven meters.
Right now, Greenland has yet to break its all-time thaw record , which dates back to the summer of 2019. The region has been experiencing upward warming for decades, accelerating since 1990. For now, experts expect the season to slow down. keep it cool and rainy enough so that the thaw doesn’t reach an extreme situation.
