Huge areas of the country became increasingly barren and less and less suitable for cattle farming.

How solar minimums affected Greenland
By J. H. Walker
Some say it was unrelenting cold and then ice, not global warming, that forced the Vikings out of Greenland.
But it was much, much worse than that. The majority of the Greenland Viking colony didn’t leave, they died in place though unrelenting cold and then ice, famine and disease, brought by the Wolf, and then Spoorer Grand Solar Minimums.
Greenland’s ice sheet kicked off 2017 gaining about eight gigatons of snow and ice, which is well above what’s usually added to the ice sheet Jan. 1 for the last 24 years, according to Danish meteorologists.
In fact, Greenland’s ice sheet has been gaining ice and snow at a rate not seen in years based on Danish Meteorological Institute (DMI) data. DMI reports the Greenland ice sheet’s “mass surface budget” has been growing significantly since October.
Greenland’s “surface mass budget” for winter 2016-2017 is already more than two standard deviations higher than the northern ice sheet’s mean snow and ice accumulation over the last 24 years. DMI data shows the ice sheet added 8 gigatons of ice and snow Jan. 1, well above the standard deviation for that day.
Update 22/10/2016: Ex-Hurricane NICOLE brings snow bomb to Greenland – 12 gigatons record Eiszuwachs in one day (see chart.)
The accumulated mass balance of Grönlandeisschildes shows on 19/10/2016 at just under 12 gigatons (12 billion tons) the highest daily gain since Beginnn the measurements (top graph, the blue line). The gray area is the range of a standard deviation of the calculated day mean (mean / average – dark gray line). Original text: “Top: The total daily contribution to the surface mass balance from the entire ice sheet (blue line, Gt / day). Bottom: The accumulated surface mass balance from September 1st to now (blue line, Gt) and the season 2011-12 (red) which had very high summer melt in Greenland. For comparison, the mean curve from the period 1990-2013 is shown (dark gray). The same calendar day in each of the 24 years (in the period 1990-2013) will have its own value.

After the harsh cold October 2016, the weather models are threatened with an unusually early winter break at the October / November 2016 monthly change.
In this case, snowfall down to the lowlands is possible.
The JRC is now expecting an imminent slump in polar ice in large parts of Europe on the night of 1 November 2016.
On the back of a large low-pressure system over north-eastern Europe air masses are performed with temperatures around minus -35 ° C in approximately 5500 m height to Central Europe in a broad stream.
Die akkumulierte Massebilanz des Grönlandeisschildes zeigt am 19.10.2016 mit knapp 12 Gigatonnen (12 Milliarden Tonnen) den höchsten Tageszuwachs seit Beginnn der Messungen (obere Grafik, blaue Linie). Die graue Fläche ist der Bereich einer Standardabweichung vom rechnerischen Tagesmittel (Mean/Durchschnitt – dunkelgraue Linie).

For comparison, the mean curve from the period 1990-2013 is shown (dark grey). The same calendar day in each of the 24 years (in the period 1990-2013) will have its own value.

Nach dem bisher kalten Oktober 2016 nicht nur in Deutschland drohen die Wettermodelle mit einem ungewöhnlich frühen Wintereinbruch zum Monatswechsel Oktober/November 2016.
Dabei sind Schneefälle bis ins Flachland möglich.
GFS rechnet heute mit einem käftigen Einbruch hochreichender eisiger Polarluft in großen Teilen Europas in der Nacht zum 1. November 2016.
Auf der Rückseite eines umfangreichen Sturmtiefs über Nordosteuropa werden in breitem Strom Luftmassen mit Temperaturen um minus -35°C in rund 5500 m Höhe nach Mitteleuropa geführt.
“We’re told that the ice in Greenland will disappear,” says Nobel Laureate Ivar Giaever. But there’s no warming there.
“There’s information on the internet, which is wonderful, says Giaever. “And I looked it up.”
There are four harbors in Greenland, says Giaever. They are Upernavik, Iluissat/Jakobshavn, Nuuk/Godthab and Tasiilaq/Ammassalik.
Look at Giaever’s chart. On the left you see the five coldest years. On the right, the five warmest years.
Now look at the dates. “The warmest years are basically in the 1930s,” says Giaever. “Those are the facts. Those are the temperatures the people in the harbors in Greenland has measured over the years. And it doesn’t look like it’s getting any warmer.”
