The study's implications are limited to the area of Antarctica surrounding the Byrd research station, as shown in this map:

The study places western Antarctica on the short list of spots in the world experiencing this degree of climate change over the last five decades, which, as you can see, are concentrated in icier -- and therefore susceptible to melting -- parts of the globe.

The new measurements fill in the gaps of an earlier study, published in 2009, that found substantial warming in the Antarctic penninsula, just to the north. But, because the data in that study was incomplete, it came under fire by skeptics (pdf) who charged that it overestimated the rate of warming. The new paper, led by David H. Bromwich of Ohio State, focuses on newly recovered data from a single temperature record -- the Byrd station's. This more detailed portrait shows that, yes, the earlier paper was indeed a bit off in its findings, but in the other direction: It underestimated the increase in temperatures, particularly in the summer months when the ice is in danger of melting. Eric Steig, the author of the 2009 paper, told The Times, "I think their results are better than ours, and should be adopted as the best estimate."

With summer ahead in Antarctica, we'll soon have another season's worth of data to study, more information with which to fill in this picture a bit. Keep filling it in, keep filling it in. The picture is getting sharper, more detailed, and more alarming year after year.
