Arctic Warming Drying Up Lakes

kingofalaska writes "An accelerating Arctic warming trend over the past quarter of a century has dramatically dried up more than a thousand large lakes in Siberia probably because the permafrost beneath them has begun to thaw, according to a paper to be published the journal Science." From the article at the LA Times: "About 125 of the 1,170 shrunken lakes disappeared altogether, and most are now considerably smaller than the study's baseline of 40 hectares, or about 99 acres, the researchers found. If Arctic temperatures continue to rise, the scientists said, many of the lakes in high northern latitudes, where they are ubiquitous, could eventually disappear."

Increasing?

To quote a paragraph from tfa;

By contrast, the scientists found that in Siberian areas where the ground below is still permanently frozen, the number of lakes actually increased by about 4% and total lake area grew by about 12% over the last three decades.

Interestingly they neglected to indicate how many hectares this 12% represented.

I guess that wasn't as dramatic a headline.

Arctic Warming Is Drying Up Lakes, Study Finds, but some lakes actually growing

nobody knows "absolutely and definitely" whether there is global warming or, if it exists, whether it is due to human activity.

Actually I think it's not at all in dispute as to whether we're experiencing any global warming. I believe that's been conclusively established. What some still heavily debate are the causes of said warming.

There's a strong correlation between atmospheric CO2 and warming and well understood atmospheric interactions of CO2, but some try to point the finger elsewhere or back to natural patterns.

What's truly astounding is the massively increasing level of outright propaganda on the subject. The scientists appear to be being left behind and the propagandists (sponsored by private industry) are taking over the show. Do a google for "CO2" -- it's a real eye opener.

Re:This != Global warming

I have a question since your a geoligist or whatnot.

I write CFD codes for polar oceans, so I can only answer your question in broadest terms.

i) Climate is not weather
ii) The climate is exceedingly complex, and global warming does not mean a uniform temperature increase across the globe.

junkscience.com is run by steven milloy. Steven milloy was a lobbyist who was paid by Phillip Morris to create a similar "group" to put forth the idea that second hand smoke is harmless.

Now he has this site up, and though he refuses to disclose his funding, he has in the past received money from oil company interests to lobby for them and do PR for them.
