Antarctic Heating and Cooling Trends

Antarctica has been showing some interesting heating and cooling trends over the past 20+ years. Even though the interior of Antarctica is generally cooling, the coastlines (particularly in the western hemisphere) seem to be warming. This data is skin-depth temperatures derived from the thermal IR channel of historical AVHRR data.

Please note, these are preliminary findings and there are errors associated with these trends. Scientists are currently working on ways of minimizing these errors to more precisely determine these trends.
