The Arctic region was the largest contributor to the positive slope in global temperatures in recent decades.
Consequently, the anomalously rapid warming in the Arctic region (that occurred prior to 2005) has been weighted more heavily in recent adjustments to instrumental temperature data (Cowtan and Way, 2013; Karl et al., 2015) so as to erase the 1998-2015 hiatus and instead produce a warming trend.
Meanwhile, other scientists have been busy determining that only about 50% of the warming and sea ice losses for the Arctic region are anthropogenic, or connected to the rise in CO2 concentrations.
The rest of the warming and ice declines can be attributed to unforced natural variability.

Recent changes to Lake Hazen, the world’s largest high-Arctic lake, are from increased heat flow from the area’s known geological features, and not from global warming as per the many alarmist media reports.
Evidence supporting this is abundant and reliable.
Northeast Canada’s Lake Hazen lies adjacent to the world-class Greenland/Iceland mantle plume.

Super salty water beneath ice could serve as a terrestrial analogue for a habitat for life on other planets.
An analysis of radar data led scientists to an unexpected discovery of two lakes located beneath 550 to 750 meters of ice underneath the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic. They are thought to be the first isolated hypersaline subglacial lakes in the world.

On Spitzbergen it was as warm 70 years ago as it is today
By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt
(German text translated by P Gosselin)
Newspapers like to write about heat and melt records in the Arctic, which supposedly had never happened before. That really sparks fear among the citizens. However an examination of the facts regularly brings amazing things to light, for example weather records from a German station on Spitzbergen during World War 2 for the period of 1944-1945.
In the journal International Journal of Climatology Rajmund Przybylak and his colleagues evaluated the data. Summary: Back then it was similarly warm as it is today

With temperatures of -30C and Arctic sea ice nearing its winter maximum, government climate scientists and their useful idiots in the press announce that Arctic sea ice is “near an all time low.”
In the actual Arctic, sea ice extent is increasing, more than
double six months ago, and essentially identical to all recent years (…)

Periods of extreme cold winter weather and perilous snowfall, similar to those that gripped the UK in a deep freeze with the arrival of the ‘Beast from the East’, could be linked to the solar cycle, pioneering new research has shown.
A new study, led by Dr Indrani Roy from the University of Exeter, has revealed when the solar cycle is in its ‘weaker’ phase, there are warm spells across the Arctic in winter, as well as heavy snowfall across the Eurasian sector.
The research is published in leading journal Scientific Reports, a Nature Publication, on Tuesday, 20 March 2018.

From NASA Goddard:
Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists at the NASA-supported National Snow and Ice Data Center (NSIDC) and NASA.
On March 17, the Arctic sea ice cover peaked at 5.59 million square miles (14.48 million square kilometers), making it the second lowest maximum on record, at about 23,200 square miles (60,000 square kilometers) larger than the record low maximum reached on March 7, 2017 (…)

How Does the Recent Melting of the Greenland Ice Sheet Compare to the Early Holocene?
Short answer: Same as it ever was. Vinther et al., 2009 reconstructed the elevations of four ice core sites over the Holocene. There has been very little change in elevation of the two interior ice core sites (NGRIP and GRIP), while the two outboard sites (Camp Century and DYE3) have lost 546 and 342 m of ice respectively.

The sunspot number for February 2018 was 10.6 and thus was some 30% below the meanfor this time into the cycle. At the moment solar activity is close to quiet.
Just 10 years ago, all the talk was about the Arctic sea ice “death spiral”, with some of scientists hysterically predicting the sea ice would soon disappear altogether in the summertime. Ten years later the scientists are now scratching their heads as sea ice has stabilized and is showing some clear signs of a rebound.

From the Snowfalls are now just a thing of the past department and the Finnish Meteorological Institute comes this press release today.
Exceptionally large amount of winter snow in Northern Hemisphere this year
The new Arctic Now product developed by the Finnish Meteorological Institute shows with one picture the extent of the area in the Northern Hemisphere currently covered by ice and snow. This kind of information, which shows the accurate state of the Arctic, becomes increasingly important due to climate change. The Arctic region will be discussed at the Arctic Meteorological Week which begins in Levi next week.

German skeptic and weather expert ‘Schneefan’ here writes how climate activist Mark C. Serreze recently announced this year’s sea ice extent was at the smallest all-time area. But since then Arctic temperatures have plummeted and sea ice area has grown to over 14 million square kilometers (…)

In his seminal 1982 book Climate, History, and the Modern World, the renown climatologist Dr. H.H. Lamb revealed that sea ice in the subarctic and Arctic regions was much less extensive during the Medieval Warm Period (9th-13th centuries) compared to today.
For example, records indicate that there were decadal and centennial-scale periods without any sea ice invading any of Iceland’s coasts. These no-ice periods coincided with atmospheric CO2 concentrations of 275 ppm, which is about 130 ppm less than today’s calculated CO2 values.

During the 1930s and 40s, and in earlier parts of the cycle, winters and spring were much warmer than, for instance, the 1960s and 70s. And, again, we see that those warmer decades were just as warm as recently.
It is these two seasons that have largely driven the annual changes.
In other words, the warmer winters we now commonly see in the Arctic are nothing new at all. They only appear unusual because we have started looking at data since 1954.

The Arctic Ocean once froze reliably every year. Those days are over.
Arctic sea ice extent has been measured by satellites since the 1970s. And scientists can sample ice cores, permafrost records, and tree rings to make some assumptions about the sea ice extent going back 1,500 years. And when you put that all on a chart, well, it looks a little scary (…)

Arctic Weather Brrrrreaking Records
Rankin Inlet, Nunavut gets cold in the winter. Located on the northwestern shore of the Hudson Bay at 62 degrees north and between Chesterfield Inlet and Arviat, the town is definitely in a remote yet exposed region. Weather is just a part of life and recently the weather has been colder than cold.
