ARCTIC NOT THE ONLY PLACE MELTING

||||||||||||||||||||||||||||||||||||||||||||||||||||||||

DAILY GREEN - NASA [has]released the results of another new study - to
considerably less fanfare than the Arctic data has received - showing
that over that in 2004-2005, Antarctica melting further inland, at
higher altitudes, during a greater number of days, on to a greater
extent on its largest ice shelf, than at any time in a quarter century:
"This image shows, in green, areas of persistent melting - the first
documented since studies began in 1987 - as detected by the Special
Sensor Microwave Imager radiometer aboard the Defense Meteorological
Satellite Program's satellites. Unlike visible sensors, Microwave
instruments can also detect melting below the snow surface."

NASA - With a surface size about 1.5 times the size of the United
States, Antarctica contains 90 percent of Earth's fresh water, making it
the largest potential source of sea level rise. It is also a place where
snow melting is quite limited because even in summer, most areas
typically record temperatures well below zero.

Nevertheless, NASA researchers using data collected from 1987 to 2006
found snow melting in unlikely places in 2005: as far inland as 500
miles away from the Antarctic coast and as high as 1.2 miles above sea
level in the Transantarctic Mountains. During the same period, they also
found that melting had increased on the Ross Ice Shelf, both in terms of
the geographic area affected and the duration of increased melting
across affected areas.
