A new analysis of weather balloon observations from the last 30 years reveals that the Antarctic has the same ‘global warming’ signature as that seen across the whole Earth, but is three times larger than that observed globally. The results by scientists from British Antarctic Survey are reported this week in Science.

Although the rapid surface warming in the Antarctic Peninsula region has been known for some time, this study has produced the first indications of broad-scale climate change across the whole Antarctic continent.

Lead author Dr John Turner of the British Antarctic Survey says,

“The warming above the Antarctic could have implications for snowfall across the Antarctic and sea level rise.  Current climate model simulations don’t reproduce the observed warming, pointing to weaknesses in their ability to represent the Antarctic climate system.  Our next step is to try to improve the models. ”
