A new sythesis of data since the 1957 International Geophysical Year shows that the Antarctic is in the grips of continental warming. Some earlier data indicated that the interior of the Antarctic was getting cooler. New analysis shows this to be false. The whole ice sheet atop Antarctic's rocky core is under the influence of global warming. In this case it's continental warming.
The report on Nature.com says "Significant warming extends well beyond the Antarctic Peninsula to cover most of West Antarctica, an area of warming much larger than previously reported." The study and data are based on research done by U.S. government and academic scientists.
