Satellite observations that provide an hour by hour picture of every part of the Arctic make it easy to forget that large areas of it had not even been even explored 80 years ago – let alone its ice extent minutely observed. This paper explores the controversy surrounding the period 1920-1950, which was a period of substantial warming in the Arctic.

As a complement to the discussion on Arctic sea ice decline at Climate Dialogue, lets take a look at the outlook for the development of existing and new economic activity in the Arctic marine region, as a result of this change.

In the long run the unfrozen north could cause devastation. But, paradoxically, in the meantime no Arctic species will profit from it as much as the one causing it: humans. Disappearing sea ice may spell the end of the last Eskimo cultures, but hardly anyone lives in an igloo these days anyway. And the great melt is going to make a lot of people rich. – The Economist

[T]he world’s military leaders . . are preparing for a new kind of Cold War in the Arctic, anticipating that rising temperatures there will open up a treasure trove of resources, long-dreamed-of sea lanes and a slew of potential conflicts.

A new paper by Polyakov, Kwok and Walsh is in press in the Bulletin of the American Meteorological Society, entitled: “Recent changes in arctic multi-year sea ice coverage and likely causes.” This is the best paper I’ve seen on this topic, which clearly articulates the complexity of the issue.

In my congressional testimony, I discussed the idea of climate change winners and losers. In the Arctic, where climate is changing most rapidly, will there be winners or losers?

The latest analysis of sea ice extent by the NSIDC shows that early June sea ice extent is lower than corresponding 2007 value. A recent article at Yale360 discusses how as Arctic sea ice retreats, storms take toll on the land.

I spent the 1990’s conducting research on the climate dynamics of the Arctic Ocean, and then moved onto other things circa 2002. My interest in the Arctic has recently been reinvigorated by the increasing societal implications of reduced sea ice extent in terms of security issues, the prospect of a northern sea route, implications for resource exploration and extraction, and adaptation issues for coastal villages along the Arctic Ocean coast.
This multi-part series will begin with an overview of what we know about the climate dynamics of the Arctic Ocean sea ice.
