The headline is "Satellites Confirm Half-Century of West Antarctic Warming"

The actual technique:

...Ground-based stations have recorded temperatures since 1957, but most of those readings come from the peninsula and areas on the edges of the continent. But at the same time, scientists such as study co-author Joey Comiso of NASA's Goddard Space Flight Center in Greenbelt, Md., have been gathering measurements from a series of Advanced Very High Resolution Radiometer (AVHRR) instruments deployed on satellites since 1981.

To construct the new 50-year temperature record, the team applied a statistical technique to estimate temperatures missing from ground-based observations. They calculated the relationship between overlapping satellite and ground-station measurements over the past 26 years. Next, they applied that correlation to ground measurements from 1957 to 1981 and calculated what the satellites would have observed.

And, of course, we're talking about 0.5 degrees C. overall, or 0.9 degrees C in the West. Over the past 50 years.

I bet we going to see a lot of that bright red painted map in the papers.

If you look at one of the related links at the bottom of the page, you can see how hard they're working at this. The headline is "NASA Finds Vast Regions of West Antarctica Melted in Recent Past." in the story we find that some surface ice melted in 2005 for about a week, and refroze without any of it flowing into the sea. And that no further melting had been detected through March of 2007. But the headline is what the newspapers will run with.
