New research suggests one more unexpected culprit: Changing winds at one end of the continent could actually be setting off a series of changes, like a set of falling dominoes, that pushes warm water below the ice at the other end, thousands of miles away.
Finding these pieces of the Antarctic melt puzzle and putting them together will help scientists better pin down how much sea level rise is in store as the world warms, and when cities from Miami to Shanghai may largely disappear from the map.
Sea levels have already risen by about 8 inches since the beginning of the 20th century from a combination of melting polar ice and the expansion of ocean waters as they absorb some of the excess heat trapped by human-emitted greenhouse gases. And while 8 inches may not seem like much, it is already causing more costly damage from coastal flooding.
Storm surges created by hurricanes and other storms, like Hurricane Sandy, are stronger and higher than in the past, and there are more instances of so-called sunny day flooding, when tidal forces push water into the streets of Miami, Norfolk, Va., and other coastal cities.
