This is the heaviest precipitation on the ice cap since records began in 1950, according to the National Snow and Ice Data Center.
Ted Scambos, senior researcher at the National Snow and Ice Data Center at the University of Colorado, said this proved that Greenland was warming rapidly.
“We’re crossing thresholds not seen in millennia, and frankly, that’s not going to change until we adjust what we’re doing to the air,” said Scambos.
