Early spring months
To say the 2016 Greenland melt period is off to the races is an understatement.
Warm, damp problems quickly banged from the melt period on the weekend, above a month-and-a-half before routine. It offers easily set an archive for earliest melt period beginning, and marks the first time it’s started in April.

Little to no melt through cold temperatures is the norm as sub-zero conditions keep Greenland’s huge ice sheet, really, on ice. The sunshine usually kicks off the melt period in belated might or very early June, but this year is a bit various.
Record warm conditions along with hefty rainfall mostly sparked 12 % of this ice-sheet to go into meltdown mode (hat tip to Climate residence's Megan Darby). The majority of the melt is focused around southwest Greenland.
Based on Polar Portal, which monitors everything ice-related inside Arctic, melt period kicks off whenever ten percent of the ice-sheet experiences surface melt. The earlier record for first begin ended up being might 5, 2010.
This April kickoff is so bizarrely early, scientists just who learn the ice sheet examined their analysis to be sure anything had beenn’t amiss before you make the statement.
“We must check that our models remained working precisely” Peter Langen, a climate scientist at the Denmark Meteorological Institute (DMI), told the Polar Portal.
But alas, the designs are working and weather condition data and stories appearing out of western Greenland have borne that out. In accordance with DMI, conditions at Kangerlussuaq, a tiny village in southwest Greenland, set an April record for that location when they achieved 64.4°F (17.8°C) on Monday. That’s just a scant .4°F (.2°C) from the all-time Greenland high for April. Hefty rain have inundated local communities.— Jason Container (@climate_ice)
The summit of the Greenland ice sheet has also been record hot. On Tuesday, it achieved 20.3°F (-6.5°C) which while obviously below freezing, is still record mild with this time of year and is around 40°F above typical. Together with wamrth actually more than yet.
Conditions could attain as high as 57°F above regular recently. It's distinctly possible more temperatures records could fall before the week is out.
Conditions anomalies for Wednesday afternoon forecast because of the Euro design. In Greenland, the temperature could attain up to 57°F above typical.
And while typical conditions are anticipated to come back, the impacts for this cozy stretch will remain using the ice sheet. Energy of all of the that melting ice is expected to wend its way somewhat further into the ice pack, making it easier for continued melt later on in period.
The Greenland ice sheet represents one of the most massive stores of ice on the planet. If it had been all to melt, it would boost oceans about 20 feet. Melting ice is also impacting sea circulation as well as the drift of North Pole.
Climate change has-been cutting into Greenland’s icy reserves, with heated air and water conditions leading to the loss of countless a great deal of ice annually. Dust and soot from forest fires in Canada and Siberia have also expedited the ice sheet’s melt.
But exactly how this melt season progresses depends a great deal from the weather. A year ago, a very good springtime kept Greenland mainly solid before a summer heat-wave generated a rapid meltdown of this ice sheet. Plus July 2012, a record-setting 95 % of this ice-sheet experienced surface melting as a result of high temperatures and soot from wildfires in Siberia.
It remains to be noticed the way the climate plays in the following months. But irrespective of this year’s climate, it's increasingly clear the planet’s ice is within for a rough ride. By 2100 the complete Greenland ice sheet could experience melting each year if conditions still rise.
