Antarctic glaciers melting 'passed point of no return'

Antarctic glaciers melting 'passed point of no return' 

And some say there is no problem. Four feet of sea level rise, just here.

"The vast glaciers of western Antarctica are rapidly melting and
losing ice to the sea and almost certainly have "passed the point of no
return," according to new work by two separate teams of scientists.

The likely result: a rise in global sea levels of 4 feet or more in the
coming centuries, says research made public Monday by scientists at the
University of Washington, the University of California-Irvine and NASA's
Jet Propulsion Laboratory."
