A sign of cooling? New permafrost is forming around shrinking Arctic lakes

Watts Up With That?

From McGill University

New permafrost is forming around Twelvemile Lake in Alaska, but researchers have concluded that this permafrost will have disappeared by the end of the century due to continued climate change.

Researchers from McGill and the U.S. Geological Survey, more used to measuring thawing permafrost than its expansion, have made a surprising discovery. There is new permafrost forming around Twelvemile Lake in the interior of Alaska. But they have also quickly concluded that, given the current rate of climate change, it won’t last beyond the end of this century.

Twelvemile Lake, and many others like it, is disappearing. Over the past thirty years, as a result of climate change and thawing permafrost, the lake water has been receding at an alarming rate. It is now 5 metres or 15 feet shallower than it would have been three decades ago. This is a big change in a very short…

    Russ,
    Do you frequent iceagenow.info? I check there every couple of days and there are a number of stories of snowfall at temperate latitudes in the northern hemisphere in mid June. In the last week, there has been snow in Wyoming, Montana, Utah and Idaho. There has also been snow reported in Norway, Finland, Estonia and northeast of Moscow, Russia. (The Souther hemisphere is having it’s share of cold weather but it is winter there afterall.) I just bring this up because there seems to be this great variability in weather that in past times would have had a tremendous impact locally on agriculture because the cold might kill crops but these days in a global economy are not as disastrous and may not be easily picked up by people only looking at averages.

      Thanks for the heads up. I have been looking for a June crop killing freeze. A clear sign that we are on the cusp of the next grand minimum.
