Ekstremalne opady pojawiły się 14 sierpnia na najwyższym punkcie lądolodu Grenlandii, na wysokości 3216 metrów n.p.m. Na pokrywę lodową spadło wówczas 7 miliardów ton wody, co wystarczyłoby, aby wypełnić staw przed pomnikiem Lincolna w National Mall w Waszyngtonie prawie 250 000 razy - oblicza amerykańska stacja CNN. To był trzeci raz w ciągu niecałej dekady i ostatni odnotowany w tym roku dzień, w którym stacja szczytowa National Science Foundation zanotowała temperaturę powyżej zera.

Scientists are sounding the alarm! First rain on the Greenland ice cap

Heavy rain fell on August 14 at the highest point of the Greenland ice sheet at 3,216 meters above sea level. Then the ice sheet fell 7 billion tons of water, enough to fill the pond in front of the Lincoln Memorial at the National. He’s monetized in Washington nearly 250,000 times, according to CNN. It was the third time in less than a decade, and the last day on record this year, that the National Science Foundation’s Summit Station recorded a temperature above freezing.

as National Snow and Snow Data Center (Information and Reference Center of America that supports polar and cryospheric research), this was The largest rainfall on the ice sheet Since the start of the search in 1950, the amount of ice mass lost on Sunday has been seven times greater than the daily average for that time of year.. This is evidence of rapid warming in Greenland, said Ted Schampos, chief scientist at the National Ice and Snow Data Center at the University of Colorado.

What’s happening isn’t just a decade or two of warmth in a stray climate Scampos told CNN. This is unprecedented added.

Greenland is experiencing its hottest summer in measured history. The temperature there is about 20 degrees Celsius. as recorded Record 23 degrees, which is unique to this region. summit station National Science Foundation It is located at the highest point in the Greenland ice sheet, where scientists can monitor Arctic weather and changes in the ice.

Because of the heavy rain, operations at the summit station will have to be altered, said Jennifer Mercer, director of programs in the Office of Polar Programs at the National Science Foundation.

This means that we must take into account weather events that we have not dealt with before in the history of our operations CNN said. Increasingly frequent weather events, including thaw, high winds, and now rain, over the past ten years Outside the range that is considered normal Mercer said. It seems that they are appearing more and more. Man-made climate change is warming the planet, which is why ice loss has increased sharply – She indicated.

The UN’s flagship climate report, published this month, found that burning fossil fuels has thawed Greenland over the past two decades.

A recent study published in the journal Cryosphere found that Earth has lost 28 trillion tons of ice since the mid-1990s, much of it coming from the Arctic, including the Greenland ice sheet. In July, the Greenland Ice Sheet experienced one of the most significant melting phenomena of the past decade, VolOver 8.5 billion tons of surface mass removed in a single day. This year, an unexpected hot spring and July heat wave caused almost the entire surface of the glacier to melt. As a result, the global sea level has risen by 1.5 mm permanently.

The Arctic is warming three times faster than in other regions of the world. Melting of the Greenland ice sheet began in 1990 and has accelerated steadily since 2000. He has lost nearly four times more weight in recent years than he did before 2000.
