Earth Observation satellites contribute to International Polar Year 2007-2008   The Larsen site in Antarctica   Time series climate data from the Antarctic Peninsula document an average temperature rise of 2.5 degrees Celsius over the last 50 years. And as can be seen in this animation, which incorporates data from the last decade by combining ERS SAR data with the first Envisat data, this warming seems to have changed the very face of the Peninsula's east coast - once completely ice-shelf bound.   This animation, comprised of images acquired by Envisat’s Advanced Synthetic Aperture Radar (ASAR), shows the C-16 iceberg and the Drygalski Ice Tongue before and after the collision that took place on 30 March 2006.   Artist's impression of Envisat.
