Antarctica, showing rates of surface-elevation change derived from satellite radar-altimeter measurements
The figure shows rates at which the ice-sheet mass was estimated to be changing based on radar-altimeter data (black), mass-budget calculations (red), and satellite gravity measurements (blue). Rectangles depict the time...

Temperature increases in the Antarctic due to climate change, 2090 (NCAR-CCM3, SRES A2 experiment)
Climate change, due to increased concentrations of greenhouse gases in the atmosphere, has not lead as clear changes in the Antarctic as in the Arctic. Some of the ice shelves of the Antarctic peninsula have split up and...
