Why Did It Rain at Greenland’s Highest Point? Global Warming Is at Play – Green Matters
So while it’s pretty obvious that global heating is a major factor here, what specifically caused the temperature to get so high at this location that rain actually fell instead of snow for the first time?
According to the National Snow and Ice Data Center, the “melting event” that occurred from August 14 to 16, 2021 was caused by a high air pressure southeast of Greenland, combined with a strong low pressure center over Baffin Island, located to the west of Greenland. The two forces blew hot, moist air up towards Greenland, which raised temperatures and caused the snow to turn to rain.
The data center added that on Aug. 14 and 15, there was significant rainfall and surface melting around Greenland’s southeast coast, which soon spread up to the summit region.
