Study shows unprecedented warmth in Arctic

(Phys.org) —The heat is on, at least in the Arctic. Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher now than during any century in the past 44,000 years and perhaps as long ago as 120,000 years, says a new University of Colorado Boulder study.

The study is the first direct evidence the present warmth in the Eastern Canadian Arctic exceeds the peak warmth there in the Early Holocene, when the amount of the sun's energy reaching the Northern Hemisphere in summer was roughly 9 percent greater than today, said CU-Boulder geological sciences Professor Gifford Miller, study leader. The Holocene is a geological epoch that began after Earth's last glacial period ended roughly 11,700 years ago and which continues today.

Miller and his colleagues used dead moss clumps emerging from receding ice caps on Baffin Island as tiny clocks. At four different ice caps, radiocarbon dates show the mosses had not been exposed to the elements since at least 44,000 to 51,000 years ago.

[Mr. H.]

Mother Earth was going through all sorts of shit before we showed up.

Now that we've showed up, she's still going through all sorts of shit.

Even in a non-hydrocarbon society, we are ultimately doomed.

I'd rather die happy than die a fucked up indignant living in a cave.

See the dead moss thread. These guys are playing loose and fast with their conclusions.
Besides---------
fact is arctic summers in the pasr 5 years are some of the coldest ever recorded.

Yeah, only if you ignore (which the AGW conmen are expert at) prior peer reviewed papers....

This contrasts with many sites on Iceland and across the Arctic that experienced an early to mid-Holocene "thermal maximum" in response to enhanced summer insolation forcing. Suppressed terrestrial temperatures along the northern coastal fringe of Iceland were most likely a result of sea surface conditions on the North Iceland shelf. In contrast, peak warmth on northeastern Baffin Island occurred during the first millennia of the Holocene, roughly in phase with peak insolation forcing. The magnitude of early Holocene warmth at Lake CF8 (5ºC warmer than present) far exceeds hemispheric averages, and implies that powerful positive feedbacks enhanced radiative forcing in this region. Early Holocene warmth was interrupted by two cold reversals between 9.5 and 8 ka, which may correlate with the well-known "8.2 event" and widespread abrupt climate changes that occurred ca. 9.2 ka. Maximum last-interglacial temperatures at Lake CF8 were not significantly different from peak Holocene temperatures.

Exposure history modeling indicates at least one additional prior period of ice cover of approximately 1000 years. This cold interval most likely occurred sometime since 4 ka, after the Holocene Thermal Maximum in the Arctic and coeval with the onset of Neoglaciation. Radiocarbon dating reveals that some plateau ice caps have been continuously present for more than 1000 years, whereas others formed early in the Little Ice Age (~520 cal BP). Even without additional warming, continuation of current climatic conditions on northern Baffin Island will result in the demise of all ice on the plateau, a condition that has not occurred for more than 1300 years.

Although the retreat chronology of the LIS during the late Pleistocene (21–11.5 ka BP) is relatively well constrained by hundreds of 14C dates and extensive moraines that document the age and position of the retreating ice margin, its subsequent Holocene retreat history remains poorly known with the exception of the Baffin Island/Foxe Basin region
(Fig. 1) (Dyke 2004; Miller et al. 2005).

See the dead moss thread. These guys are playing loose and fast with their conclusions.
Besides---------
fact is arctic summers in the pasr 5 years are some of the coldest ever recorded.

Really?

Yes really. Is there a warmer on this board that DOESNT have areading problem? SUMMERS !!!

Your link doesn't make any claims or present any evidence concerning Arctic TEMPERATURES.

Now who is it that has trouble reading?

Yep they ALL SEEM to be barely literate and functional...

I heard it's warmer than it's been in a million billion years.

Think of the electrons you're wasting dude.

 

[Toddsterpatriot]

Think of the CO2 emitted for your response, dude.

Of course, skook also thinks Hurricane Sandy was caused by government vortex weapons. As do many denialists. After all, if someone is stupid and brainwashed enough to embrace the 'tard conspiracy theory of denialism, then they'll be crazy enough to fall for every other 'tard conspiracy theory out there.

And you think that Sandy was some super duper hurricane, which it wasn't. Non-sequiter much?

Sucks to be so wrong so frequently huh! I almost feel sorry for you.....almost!

Yeah they try tell you that the arctic sea ice melt is still "accelerating".
Mean while it has not just slowed down but grew again since 2008:

First in words
2008. Average sea ice extent over the month of September, a standard measure in the scientific study of Arctic sea ice, was 4.67 million square kilometers

Arctic sea ice extent averaged for September 2013 was 5.35 million square kilometers
And then a side by side picture:

And all the while the antarctic ice is growing and setting new records.

 

[mamooth]

If denialists can't grasp that yearly variability and the long-term trend are different things, there's no point in trying to reason with them.

 

[Abraham3]

Here are the Arctic ice extents for September. The magenta line is the median ice extent for 1981-2010.
