Where’s the warming!
The Arctic and North Atlantic have suddenly turned surprisingly cold. First, according to Weatherbell meteorologist Joe Bastardi, the northern Atlantic has turned cold; so cold in fact that Bastardi called it “impressive”: …
All the Atlantic cold could have a big (positive) impact on the upcoming hurricane season, says hurricane expert Philip Klotzbach. One week ago Klotzbach tweeted …

From the “skating on thin ice” department.
According to a new paper published in the Journal of Geophysical Research, the observed mean thickness of the sea ice in the region north of (Arctic) Svalbard was substantially thinner (0.94 m) in 1955 than it has been in recent years (~1.6 m, 2015/2017).

Arctic sea ice volume is the highest for the date in 13 years, and melt is the slowest on record.

According to the Danish Meteorological Institute, Arctic sea ice volume is highest for the past eleven years and above the fifteen year mean since the start of DMI records in 2003.

DDuring a meeting of polar bear range states (Canada, Russia, Greenland, Norway, and the USA) in late January 2018 to discuss conservation issues, Canada — home to ~2/3 of the world’s polar bears — included in its presentation an updated population status and trend map approved by the Polar Bear Technical Committee in its presentation. This 2017 map replaces one from 2014 but is not yet available on the Environment Canada website.

And 60 years later, both the Northwest Passage and Northern Sea Route are blocked by 12-foot thick ice.

As the current solar cycle nears an end, it will go down as the weakest in close to 200 years. And as inhabitants of the northern hemisphere dig themselves out of an especially icy and snowy winter and Arctic sea ice rebounds, it may all be in part linked to low solar activity as many scientific studies have long suggested.

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 (…)
