Arctic perennial sea ice, which normally survives the summer melt season and remains year-round, shrunk abruptly by 14 percent between 2004 and 2005, according to data from the National Aeronautics and Space Administration (NASA).

The overall decrease in winter Arctic perennial sea ice totals 280,000 square miles — an area the size of Texas. Perennial ice can be 10 or more feet thick. It was replaced by new, seasonal ice only about one to seven feet thick that is more vulnerable to summer melt.
