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.

“It is tempting to say that the record low we are seeing this year is global warming finally catching up with Antarctica,” Meier said. “However, this might just be an extreme case of pushing the envelope of year-to-year variability. We’ll need to have several more years of data to be able to say there has been a significant change in the trend.”

Weather and climate analyst Schneefan here writes of “early frost” in the Arctic and how Greenland snow and ice have grown after being hit by a “snow bomb”. This contradicts the expectations of global warming alarmists.
The polar summer this year appears to have ended prematurely. The mean temperature of the central Arctic above 80°N has remained under the long-term average over the entire summer and even dipped below the freezing point about a week earlier than normal (1958-2002 mean).

Greenland’s melt season ended a month ago, and since last September the ice sheet has grown at close to record rate.

Last year, experts announced that the Arctic would be ice-free in 2017.

Winter has arrived about 10 days early in the Arctic, and Greenland’s surface has gained 500 billion tons of ice – about 33% above normal.

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?
This change in Arctic climate is often promoted as evidence that humans are causing drastic climate change. For instance, an April 29th 2017 article in the Economist (“Skating on thin ice”, pg 16) implied that the Arctic is melting unusually, dramatically and worryingly (…)

In recent months, two new papers published in The Cryosphere have provided a condensed summary of the ice-melt and sea-level-rise consequences of global warming for the Arctic region.
1. Between 1900 and 2010, the Greenland Ice Sheet (GIS) has melted so extensively and so rapidly that the GIS ice-melt contribution to global sea level rise has amounted to 1.5 centimeters for the entire 110-year period. One-and-a-half centimeters. That’s 0.59 of an inch!
2. It gets worse. Between 1993 and 2010, the contribution to global sea level rise has been a disturbing 0.39 of a centimeter. Almost 4/10ths of a centimeter. That’s 0.15 of an inch!

In sharp contrast with previous decades, the past 10 years have seen no change in Northern Hemisphere average sea ice extent, according to MASIE (may-zee, Multi-sensor Analyzed Sea Ice Extent) database from the National Sea & Ice Data Center (NSIDC; see figure 1).

The Greenland Ice Sheet is gaining near record amounts of ice this year. Very little melting has occurred this summer, which is about to start winding down. Temperatures on the Greenland Ice Sheet have been extremely cold, and broke the all-time record for Northern Hemisphere July cold on July 4, at -33C.
