Since the last temperature records studied ended in 2010, I'll concede that technically you are correct. However, by all accounts, the Arctic has continued to warm at an increasing rate since 2010, so it is entirely plausible that the trend identified in the study up to 2010 can assume to have continued since then.

Some of the data I'm using to conclude that the Arctic is continuing to warm at an increasing rate include --

In four of the last seven years since 2010 Arctic Sea Ice extent has been less than that of 2010. And those years were all record-breaking years since satellite record-keeping commenced in about 1980. And probably these last 10 years have been less than anytime in the last 100 years, and possible less than anytime in the last 10,000 years.

February 2018 just set the record for the lowest MAXIMUM sea ice extent, for the month of February, since satellite record-keeping began.
it kinda fits with the temperature reconstructs from the maunder minimum

High-energy, high-fat lifestyle challenges an Arctic apex predator, the polar bear | Science

Published 02 February 2018
Quote:
A demanding lifestyle
Polar bears appear to be well adapted to the extreme conditions of their Arctic habitat. Pagano et al., however, show that the energy balance in this harsh environment is narrower than we might expect (see the Perspective by Whiteman). They monitored the behavior and metabolic rates of nine free-ranging polar bears over 2 years. They found that high energy demands required consumption of high-fat prey, such as seals, which are easy to come by on sea ice but nearly unavailable in ice-free conditions. Thus, as sea ice becomes increasingly short-lived annually, polar bears are likely to experience increasingly stressful conditions and higher mortality rates.

Abstract
Regional declines in polar bear (Ursus maritimus) populations have been attributed to changing sea ice conditions, but with limited information on the causative mechanisms. By simultaneously measuring field metabolic rates, daily activity patterns, body condition, and foraging success of polar bears moving on the spring sea ice, we found that high metabolic rates (1.6 times greater than previously assumed) coupled with low intake of fat-rich marine mammal prey resulted in an energy deficit for more than half of the bears examined. Activity and movement on the sea ice strongly influenced metabolic demands. Consequently, increases in mobility resulting from ongoing and forecasted declines in and fragmentation of sea ice are likely to increase energy demands and may be an important factor explaining observed declines in body condition and survival.

Climate denier blogs ignore sea ice and polar bear science, study finds | CBC News

Nov 29, 2017
Quote:
...[regarding polar bear research] About 80 per cent of denier blogs cited the work of University of Victoria zoologist Susan Crockford, even though she has published almost no peer-reviewed research on polar bears and hasn't done any field studies.

Crockford, who writes the Polar Bear Science blog, has been associated with think-tank the Heartland Institute, which denies climate change, and spoke at one of its conferences as recently as last spring...

Crockford says polar bear numbers remain strong and suggests the bears will be able to adapt to changes in sea ice.

Most scientists say that while some populations are doing fine, others — especially southern ones — are increasingly unhealthy. They say all populations risk sudden collapse once sea ice shrinks too much...

The really significant content of a new paper being heavily-hyped by the media1 is what wasn’t said rather than what the authors discovered about metabolic rates and weight maintenance of a small sample of nine Southern Beaufort Sea bears in 2014 to 2016 (Pagano et al. 2018; Whiteman 2018).

Re: Northwest Passage - 2018

Oh goody, dueling links again.

https://climateaudit.org/2017/12/18/...ical-lipstick/

In line with the high standards of climate science “communication”, there are over 50 occurences of various forms of the derogatory labels “denier” or “deny” in a mere five pages of text and two pages of references. Such derogatory language has become commonplace in the climate change academic world and reflects badly on the authors who use it.
The paper offers nothing new in terms of scientific research on polar bears or on any other topic, so to justify publication, it includes a superfluous “study” of the views held on the subject within blogs and academic papers. My concern is with the accompanying data and statistical analysis providing the “scientific” veneer for their discussion.


https://nigguraths.wordpress.com/201...dent-analysis/

"Of the 92 papers included in the study, 6 are labeled ‘controversial.’ Of the remaining 86, 60 are authored or co-authored by Stirling or Amstrup, or Derocher. That is, close to 70% (69.76%) of the so-called ‘majority-view’ papers are from just three people, 2 of whom wrote the attack paper themselves."

StuM wait till I show it all to be driven by the sun btw 47% of days with no sunspots this year already
Colder days ahead. Wonder how the ice will do this summer considering how thick it is in the nwp compared to the last several years.

Solar scientists do not support your assertion.

The Maunder minimum occurred in the middle of the Little Ice Age; it could not have sparked it.

Quote:
We conclude that winters in which the Thames froze are not at all good indicators of the hemispheric or global mean temperatures, although well-correlated with the lowest temperatures in the local observational record, the CET. The often-quoted result that they were enhanced during the solar Maunder minimum is false. Thames freeze years are slightly more frequent before the Maunder minimum began and also considerably more common 65 years after it ended. The association of the solar Maunder minimum and the Little Ice Age is also not supported by proper inspection and ignores the role of other factors such as volcanoes. Together these mean that, although the LIA covers both the Spörer and Maunder solar minima, it also persisted and deepened during the active solar period between these two minima. The latest science indicates that low solar activity could indeed increase the frequency of cold winters in Europe, but that it is a phenomenon that is restricted to winter and is just one of a complex mix of factors.

Arctic has warmest winter on record: 'It's just crazy, crazy stuff' The Guardian

Quote:
...The [Arctic] region experienced its warmest winter on record. Sea ice hit record lows for the time of year, new US weather data revealed on Tuesday.

“It’s just crazy, crazy stuff,” said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado, who has been studying the Arctic since 1982. “These heat waves – I’ve never seen anything like this.”

Experts say what’s happening is unprecedented, part of a global warming-driven cycle that probably played a role in the recent strong, icy storms in Europe and the north-eastern US.

The land weather station closest to the North Pole, at the tip of Greenland, spent more than 60 hours above freezing in February. Before this year, scientists had seen the temperature there rise above freezing in February only twice before, and then extremely briefly. Last month’s record-high temperatures have been more like those typical of May, said Ruth Mottram, a climate scientist at the Danish Meteorological Institute.

Of nearly three dozen different Arctic weather stations, 15 of them were at least 10F (5.6C) above normal for the winter.

“The extended warmth really has staggered all of us,” Mottram said.

In February, Arctic sea ice covered 5.4m sq miles, about 62,000 sq miles smaller than last year’s record low, the ice data center reported, and it was 521,000 square miles below the 30-year normal...

Re: Northwest Passage - 2018

are you sure this is a current news article. Sounds oddly like one that was printed in 1922.
( recently quoted in a senate hearing on cagw) about 4 years ago)
here it is from 10 years ago
https://wattsupwiththat.com/2008/03/...icebergs-melt/

And from snopes
https://www.snopes.com/fact-check/warm-welcome/

( just so you know it was fact checked.)
arctic weather and ice is cyclic in nature

I suppose you were hoping that we wouldn't notice that the news article you resurrected is referring to summer sea ice extent, whereas the current news articles are about winter temperatures and sea ice extent.

Lest anyone be confused about how the 1922 summer sea ice extent compares to recent summer sea ice extent, let us look at this recently-posted reconstruction of summer Arctic sea ice extent.

The y-axis units are in millions of square kilometers
As can be seen, sea ice extent for 1922 appears to be greater than 8 million km^2, whereas sea ice extent in the last decade has decayed to below 7 million km^2.

Any way you look at it, summer or winter, Arctic temperatures are rapidly increasing, and Arctic sea ice is diminishing.

no I wasn't trying to deceive anyone the article I linked to sounds just like they were talking last summer .
