“I cannot tell how long this open water patch will remain open, but even if it closes in few days from now, the harm will be done: the thick old sea ice will have been pushed away from the coast, to an area where it will melt more easily,” he added. This year’s openings are driven more by wind than melting but they have occurred during two temperature spikes. In February, the Kap Morris Jesup weather station in the region is usually below -20C, but earlier this year there were 10 days above freezing and warm winds, which unlocked the ice from the coast.
Keld Qvistgaard, the ice service coordinator in Denmark, said this was not the first time a gap had appeared between the shore and the main ice pack but the one formed from 1 to 5 August was different in its extent. “This event is a pretty big one going all the way to west of Kap Morris Jesup. This is unusual,” he said. As well as reducing ice cover, the ocean intrusion raises concerns of feedbacks, which could tip the Earth towards a hothouse state. Freakish Arctic temperatures have alarmed climate scientists since the beginning of the year. During the sunless winter, a heatwave raised concerns that the polar vortex may be eroding. This includes the Gulf Stream, which is at its weakest level in 1,600 years due to melting Greenland ice and ocean warming. With lower circulation of water and air, weather systems tend to linger longer.
Santa has a suntan this year . That's probably the same dormant hotfront as has been covering the entire northern hemisphere for most of the year causing record temperatures and fires from California to Japan to Europe , as we heard a week or so ago
A dormant hot front has been blamed for record temperatures in Lapland and forest fires in Siberia, much of Scandinavia and elsewhere in the Arctic circle.
