NASA has found that the western shores of Antarctica have been melting from below instead of above. This is because the ocean is getting warmer and warmer faster than the air above it. In the video below, please note that the shelf thickness (how thick the ice is) is indicated by color. Red would be thick (550 meters or thicker) and blue would be thinner (200 meters or thinner).
The information in this graphic was gathered by NASA's ICESat, which was launched in January of 2003. It stand for Ice, Cloud, and land Elevation. It is located in orbit around Antarctica, and scientists collected data on how ice was melting from October of 2005 to 2008. They concluded that nearly half of all ice shelves were melting from below.
