You may wonder why you have not heard much about Arctic sea ice death spirals and Greenland heatwaves this winter.
Hardly surprising, because the Arctic stubbornly refuses to follow the agenda.
Average sea ice extent last month was the highest since 2013, and stands as high as it did in 2005.

Inuit paying the price of rising bear populations
The 2018 State of the Polar Bear report, published today by the Global Warming Policy Foundation, confirms that polar bears are continuing to thrive, despite recent reductions in sea ice levels. This finding contradicts claims by environmentalists and some scientists that falls in sea ice would wipe out bear populations.
The report’s author, zoologist Dr Susan Crockford, says that there is now very little evidence to support the idea that the polar bear is threatened with extinction by climate change.
From 1972 until 2010,1 the Polar Bear Specialist Group (PBSG) of the International Union for the Conservation of Nature (IUCN) published comprehensive status reports every four years or so, as proceedings of their official meetings, making them available in electronic format. Until 2018 – a full eight years after its last report – the PBSG had disseminated information only on its website, updated (without announcement) at its discretion. In April 2018, the PBSG finally produced a standalone proceedings document from its 2016 meeting, although most people would have been unaware that this document existed unless they visited the PBSG website.
This State of the Polar Bear Report is intended to provide a yearly update of the kind of content available in those occasional PBSG meeting reports, albeit with more critical com- mentary regarding some of the inconsistencies and sources of bias present in the corpus of reports and papers. It is a summary of the state of polar bears in the Arctic since 2014, rela- tive to historical records, based on a review of the recent and historical scientific literature. It is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in polar bears and Arctic ecology.

February is not over, and Arctic sea-ice extent is already over half a million square kilometers higher than last year at this day.
The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous four years and six out of the last 14 years.
Arctic sea-ice has stubbornly resisted the very warm years between 2015-2017 caused by the big El Niño. Are we going to see an increase in Arctic sea-ice over the next few years? Only time will tell, but the idea cannot be discarded.

Arctic sea ice extent in January has recovered sharply since last year, and stands at the highest level since 2013, and higher than even 2005.

New findings from an international ocean observing network are calling into question the long-standing idea that global warming might slow down a big chunk of the ocean’s “conveyor belt.” The first 21 months of data from sensors moored across much of the North Atlantic are giving new insight into what controls the strength of the Atlantic Meridional Overturning Circulation, a system of currents that redistributes heat around much of the Western Hemisphere.

Charismatic Swiss meteorologist Jörg Kachelmann posted a comment at Twitterwhere he wondered what flagship German ZDF television was thinking when its evening news announced the polar vortex was some sort of new phenomenon arising from global warming.
Recently in the media we’ve been hearing a lot about the junk science that a warmer Arctic is somehow miraculously producing extreme cold over vast neighboring continents.

Two new species of fungi have made an appearance in a rapidly melting glacier on Ellesmere Island in the Canadian Arctic, just west of Greenland. A collaborative team of researchers from Japan’s National Institute of Polar Research, The Graduate University for Advanced Studies in Tokyo, Japan, and Laval University in Québec, Canada made the discovery.
The scientists published their results on DATE in two separate papers, one for each new species, in the International Journal of Systematic and Evolutionary Microbiology.
“The knowledge of fungi inhabiting the Arctic is still fragmentary. We set out to survey the fungal diversity in the Canadian High Arctic,” said Masaharu Tsuji, a project researcher at the National Institute of Polar Research in Japan and first author on both papers. “We found two new fungal species in the same investigation on Ellesmere Island.”

However, a recent paper authored by Elisabeth A. Barnes, Department of Atmospheric Science, Colorado State University, says the data to support this just aren’t there.

Just last March, the Guardian was trying to panic us about record lows in Arctic sea ice during last winter.
Back in the real world, DMI confirm that average Arctic sea ice extent in December was higher last month than in 2006. In reality, there has been very little change at all since 2005.

Marine ice cliff instability (MICI) “has not been observed, not at such a scale,” “might simply be a product of running a computer model of ice physics at a too-low resolution,” ignores post glacial rebound, couldn’t occur before ” until 2250 or 2300″… Yet “the idea is cinematic,” “it’s just common sense that Antarctic glaciers will develop problematic ice cliffs” and something we should plan for…
“Our results support growing evidence that calving glaciers are particularly sensitive to climate change.” Greenland’s climate is always changing… Always has and always will change… And the climate changes observed over the last few decades are not unprecedented. The Greenland ice sheet is no more disappearing this year than it was last year and it is physically impossible for the ice sheet to “collapse” into the ocean.

On December 14, 2008, former presidential candidate Al Gore predicted the North Polar Ice Cap would be completely ice free in five years. As reported on WUWT, Gore made the prediction to a German TV audience at the COP15 Climate Conference:

The media, alarmist scientists and many leading policymakers often tell the public “the Arctic is rapidly melting”. And if a poll were done today, a vast majority of the people in Japan and elsewhere would say this is true. Unfortunately they have become the victims of “fake news”.
Luckily we have some hard data from the Arctic. And if one looks at them, it is true that sea ice has seen a declining trend – if we go back 40 years.
Yet, if we look at the past 12 years, we see that the trend for minimum has stopped, and one could argue even reversed:

According to NASA, the increased rate of thickening of sea ice in the Arctic is due to Global Warming.

I guess we should count ourselves lucky the world isn’t currently in a cooling phase, otherwise we might lose the Arctic icepack altogether.

The Danish Meteorological Institute (DMI) also performs daily simulations of how much ice or water the Ice Sheet loses or accumulates. Based on these simulations, an overall assessment of how the surface mass balance develops across the entire Ice Sheet is obtained (Fig. 4).
At the end of the 2018 season (31 August 2018), the net surface mass balance was 517 Gt, which means that 517 Gt more snow fell than the quantity of snow and ice that melted and ran out into the sea. This number only contains the balance at the surface, and thus not the total balance, which also includes melting of glaciers and calving of icebergs.
Although the total SMB (Surface Mass Budget) for the 2016-2017 and 2017-2018 seasons are similar, development during the two seasons has been very different. Last year, the season began by gaining a lot of mass during the winter, whilst the development in SMB from the summer onwards reflected the long-term average. During the 2017-2018 season, SMB remained in line with the average from 1981-2010 until the summer, after which the development in SMB was higher than average.
