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.

Fifteen years of satellite measurements have unexpectedly shown that parts of Greenland are getting colder. But the scientists who produced these results urge people to believe that this cooling trend is a blip, because climate models say Greenland should be warming.

A few years ago, 10 glaciologists publishing in the journal Nature Geoscience asserted that “large parts of the north-central Greenland ice sheet are melting from below” due to high geothermal heat flux forcing (Rogozhina et al., 2016).
In a new paper published in Scientific Reports, 4 more glaciologists (Rysgaardet al., 2018) report that “hot vents” (or hot springs) of geothermally-heated water underneath the Greenland ice sheet can explain localized rising temperatures and glacial melting.

NINE YEARS AGO THIS MONTH—
Al Gore predicted the North Polar Ice Cap would be completely ice free in five years.
Gore made the prediction to a German audience in 2008. He told them that “the entire North ‘polarized’ cap will disappear in 5 years.”
This wasn’t the only time Gore made his ice-free prediction. Gore’s been predicting this since 2007.

Earlier observations showed that Arctic ice extents were low in the 1940s, grew thereafter up to a peak in 1977, before declining. That decline was gentle until 1994 which started a decade of multi-year ice loss through the Fram Strait. There was also a major earthquake under the north pole in that period. In any case, the effects and the decline ceased in 2007, 30 years after the previous peak. Now we have a plateau in ice extents, which could be the precursor of a growing phase of the quasi-60 year Arctic ice oscillation.

Rapid expansion of the Arctic sea ice cover is the norm for October as solar input dwindles and the remaining heat in the upper ocean is released upwards, warming the lower atmosphere and escaping to space. Because of late season growth, the seasonal Antarctic maximum we previously reported as occurring on September 15 was exceeded, with a new maximum set on October 11 and 12. This is the second-lowest and second-latest seasonal maximum extent in the satellite record.

A year ago the media was full of fake Arctic heatwave news (…)
And a year later?
Arctic sea ice extent this October was the third highest since 2006, and continues to track recent years. Most of the Arctic basin is full of 2 meter+ thick ice, in stark contrast to 2008.

Scientists: ‘Loud Divergence Between Sea Level Reality And Climate Change Theory’
Global Sea Level ‘Acceleration’ Just 0.002 mm/year

Extents expanded rapidly during the last 12 days of October through yesterday, especially on the Eurasian side. At the top center the Laptev Sea fills in completely, and to the left East Siberian Sea is also growing solid ice toward East Asia. Kara sea on the right is growing fast ice from the shore outward, while the Barents Sea fills in from the central Arctic.

A year ago I wrote an article at WUWT analyzing the recent upward trend in summer Arctic sea ice extent. Despite challenges of statistical irrelevancy, the trend has continued another year. Arctic ice experts, that have repeatedly predicted the demise of summer ice, don’t have an explanation for a 10-year trend that contradicts their predictions, beyond statistical variability or unexplained natural variability.

The extraordinary sight was witnessed by tourists on an Arctic cruise aboard the Finnish-built MV Akademik Shokalskiy.
A source at Wrangel Island Nature Reserve said: “There were at least 230 polar bears, including single males, single females, mothers with cubs and even two mothers with four cubs each.”
Experts called the sight of so many polar bears together “unique”. The huge number could in fact amount to as much one per cent of the entire world’s population of the creatures.

Overall, initial figures suggest that Greenland may have gained a small amount of ice over the 2016-17 year. If confirmed, this would mark a one-year blip in the long-term trend of year-on-year declines over recent decades.
