Just to make my position clear, its pretty obvious the arctic is warming, but all that you see here at RC from commentors is that the ice melting is proof of global warming and the disasters that will ensue, when in fact warmth was but a small factor in this years arctic ice minimum.

Many commentators are proclaiming, more in sorrow than in anger, that the melting of arctic pack - ice (which was high again this year) is a certain indicator of global warming.

Polar bears in the arctic would typically put on a fat blubber layer going into late winter, Dewar said, but Anana, a city bear, doesn't have that blubber layer this year due to our warmer climate.

And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

The article claims arctic temperatures are the warmest they've been in 2000 years.

There was a warm period about three thousand years ago with an open arctic that replenished ice, then it got cold, polar oceans froze, snowfall diminished and ice depleted until it got warm in the Roman warm period about two thousand years ago.

Now, since 2007, at the height of the global warming scare tactics about arctic sea ice, the antarctic sea ice extents anomaly CONTINUOUSLY exceeds 1.25 Mkm ^ 2 for 3 years straight now, and is larger than 1.5 Mkm ^ 2 so often for such long times that it is not even newsworthy on a skeptic site.

This grim fact is even bleaker if the international community concludes that it should limit warming to 1.5 degrees C, a conclusion that might become more obvious if current levels of warming start to make positive feedbacks visible in the next few years such as methane leakage from frozen tundra or more rapid loss of arctic ice.

As a massive blanket of arctic air brings twenty - year record cold temperatures to the United States, it's not surprising to see the Church of Global Warming in full - on shrieking panic mode, screaming at the top of their lungs that a blast of cold weather doesn't disprove their theories.

By John Hayward — As a massive blanket of arctic air brings twenty - year record cold temperatures to the United States, it's not surprising to see the Church of Global Warming in full - on shrieking panic mode, screaming at the top of their lungs that a blast of cold weather doesn't disprove their theories.

Anyone else see a dichotomy here both say the arctic warming has been known for years.

That a simple warming trend throughout the 20th century does not characterise arctic conditions is also confirmed by records of ice cover in the four seas that lie north of Siberia (Kara, Laptev, East Siberian and Chukchi); these show clearly that ice variability in these seas is dominated by a low frequency oscillation of frequency 60 ‐ 80 years that «places a strong limitation on our ability to resolve long term trends».

I was most struck by the scientific reports from the arctic in the 1940's that SST's in many parts of the Arctic were up to 10C warmer than measured by Nansen fifty years earlier.

While NASA says sea ice probably won't set any records this year, we have this horrible news: Sea ice decline spurs the greening of the Arctic Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to two University of Alaska Fairbanks scientists.

This warming was very wide spread from the 1920's to the 1940's and included the «dust bowl» years in America, retreat of glaciers and the warming of the arctic to levels that approached, but probably did not reach, modern levels, as was noted in this previous Climate Etc. article.

so that proves global warming, even thought the average global temp is the same as sixteen years ago and the arctic ice cap area is the highest in a decade and the Antarctic ice cap is the highest in four decades.

Considering that there were places in the Arctic this summer that were 7 to 10C warmer than average this past winter, while some of us in the eastern and southern US froze our tails off — we got a very unusual freeze in S. Texas — due to the strongly negative arctic oscillation (weather patterns go north to south instead of west to east), and considering that the data gaps are more in the Arctic and inaccessible places, not here, one would expect GISS to come up with a somewhat warmer average than Hadley & others this year.
