A comprehensive study of the Antarctic Peninsula, using aerial photographs dating back to the 1940s and more recent satellite images, shows that most of the area’s glaciers have been steadily retreating for the last 50 years. The rate of retreat has increased since the millennium. It can’t all be explained by global warming, and some glaciers have grown (32, compared to the 212 that have shrunk), but man made effects have exacerbated natural climate variations.
