Greenland melt seems to be picking up speed, blah blah blah
More than two trillion tons of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming.
Did you catch that, my friends? "What scientists say is global warming..." a couple of drinks and you could probably get them to say almost anything.
Scientists studying sea ice will announce that parts of the Arctic north of Alaska were about 5 to 6 degrees Celsius, or 9 to 10 degrees Fahrenheit, warmer this past autumn, a strong early indication of what researchers call the Arctic amplification effect... As sea ice melts, the Arctic waters absorb more heat in the summer, having lost the reflective powers of vast packs of ice. That absorbed heat is released into the air in the autumn. That has led to autumn temperatures in the last several years that are 3.5 to 6 degrees Celsius warmer than they were in the 1980s...
"The pace of change is starting to outstrip our ability to keep up with it, in terms of our understanding of it..." (In other words, they're making it up... Ed.)
Two other studies presented at the conference assess how Arctic thawing is releasing methane - a potent greenhouse gas. One study shows that the loss of sea ice warms the water, which warms the permafrost on nearby land in Alaska, thus producing methane...
A second study suggests even larger amounts of frozen methane are trapped in lake beds and sea bottoms around Siberia and they are starting to bubble to the surface in some spots in alarming amounts, said Igor Semiletov, a professor at the University of Alaska in Fairbanks (where Putin rears his head... Ed.). Late last summer, Semiletov found methane bubbling up from parts of the East Siberian Sea and the Laptev Sea at levels 10 times higher than those of the mid-1990s, he said.
The amounts of methane in the region could dramatically increase global warming if they get released, he said.

This calls for more research.
