Climate Change You Can Believe In Antarctica Is melting fast! NASA Scientist and researchers alike agree that this is "past the point of no return," NASA glaciologist Eric Rignot told reporters by phone Monday according to CNN. According to NASA and The United Nations' most recent climate change report estimates sea levels could rise from about 1 foot to 3 feet by 2100, levels that could displace tens of millions of people from coastal areas around the world. That report did not take into account the current situation on the west coast of Antarctica. The ice melting in Antarctica has increased 77% since 1973. According to NASA warm water flowing from climate change regions began to dissolve the massive glaciers at the base until they break off and head to warmer waters in the oceans.  This latest iceberg to break off the glacier is the size of Atlanta according to NASA reports. This creates an unstoppable chain reaction.
