Baked Alaska: Climate Change in the Arctic

Posted January 2, 2015

Arctic Report Card

"The NOAA releases its latest Arctic Report CardIf there’s been any “pause” in global warming, the Arctic hasn’t seen it. The latest Arctic Report Card issued from the National Oceanic and Atmospheric Administration (NOAA) shows a continued acceleration of climate change in the region.

This latest report shows that Arctic air temperatures continue to rise at more than twice the rate of global temperatures, a phenomenon scientists call “Arctic amplification,” causing a range of impacts. Among them are increasing air and sea surface temperatures, declining reflectivity (albedo) of Greenland’s ice sheet, diminishing spring snow cover on land and summer ice on the ocean, and the declining health and numbers of some polar bear numbers, including those in the Hudson Bay region.

The Arctic is the climatic canary in a coal mine, impacting not only Arctic populations and ecosystems, but the global climate system as well."

And I though Baked Alaska was some cholesterol filled decadent dessert!

Looking Ahead in the Arctic, With the United States on Point
An American admiral is in line to lead the eight-nation Arctic Council as a climate steward and a caretaker of the ocean.

Enrico Mantle Methane Eruption Anomaly in N. Alaska, here;
http://arctic-news.blogspot.com/2015/02 ... -2031.html
With the 2014 blowholes and huge methane spikes in Siberia, the Arctic is +6*C, past the point where in PETM and the Permian started partial methane turnover from global CO2 of volcanic origins over a relatively short time. Now humans are causing changes 10 to 40 times as much and fast. AND we haven't even really seen the rapidity of change as much as we will before the end.

Last year Siberia was up to 9*C warmer-----Alaska will follow. :-k

Usually a warm Alaska correlates well to a cold CONUS, and this year is no exception.

I take it you do not believe the charts showing an average of 6*C increase in the general Arctic region. Or it could be a lack of study in paleoclimatology in the geologic record.

"Understanding Time of Observation Bias

Posted on 6 March 2015 by Guest Author

This is a guest post by Zeke Hausfather

Global temperatures are adjusted to account for the effects of station moves, instrument changes, time of observation (TOBs) changes, and other factors (referred to as inhomogenities) that cause localized non-climatic biases in the instrumental record.

While the impact of adjustments that correct for these biases are relatively small globally (and actually reduce the century-scale warming trend once oceans are included) there are certain regions where the impact of adjustments on temperature trends are large. The United States, in particular, has large adjustments to temperature data that have the effect of nearly doubling the warming trend since 1900. The U.S. is somewhat unusual in that most of its historical temperature records were collected by volunteers rather than civil service employees. This has the benefit of giving the U.S. many more records than most other parts of the world, but contributes to the fact that stations in the U.S. tend to have quite a few systemic inhomogenities.

There are two specific changes to the U.S. temperature observation network over the last century that have resulted in systemic cooling biases: time of observation changes at most of the stations from late afternoon to early morning, and a change in most of the instruments from liquid in glass thermometers to MMTS electronic instruments. Back in July I posted a general introduction to U.S. temperature adjustments that looked at the relative effect of each adjustment. Here I will focus in detail on the Time of Observation adjustment, which is responsible for the majority of the change in U.S. temperatures vis-à-vis raw data. In a future post I will address the pairwise homogenization algorithm, which attempts to correct "

Actually Snowy was pointing out that a warm Alaska usually means a cold continental US, which as we know has been in the news this year. Thus a warm Alaska would be supproted.

Alaska has the northern methane release anomaly, but Siberia had all the huge methane 'burps' last summer. The warmer Alaska/colder CONUS is not beyond historical----yet.
What I pointed out is that in the geologic record of the Permian Great Dying and the PETM were both methane runaways to partial turnover with much less methane than now and they started into runaway at 5+C. The Arctic is now +6*C, so beyond that. Dig?
The so called hockey stick of the beginning of near vertical temperature and atmospheric carbon is only starting its incredibly rapid ascent. Methane turnover of hundreds of times the carbon of now in the atmosphere, I wonder if it will stop at just a partial turnover or complete to baking everything including Alaska.
