...Remotely sensed data, (click here) including astronaut images, have recorded the position of the ice front over the years. A comparison of this October 2013 image with older data (January 2004 and January 2001, as well as October 2009) indicates that the ice front has moved backwards -- upstream -- about 3 kilometers (2 miles). This retreat is believed by scientists to indicate climate warming in this part of South America. The warming not only causes the ice mass to retreat, but also to thin. A study of 63 glaciers by Rignot et al has shown that this is a general trend in Patagonia....
Patagonia is about 4,359 miles from Antarctica.
