About
40 percent of Greenland's ice sheet thawed at or near the surface on
July 8.
Four days later, the melt had dramatically accelerated and an estimated 97 percent
of the ice sheet surface had thawed.
Three satellites found that 97 percent of Greenland underwent a thaw never before seen in 33 years of satellite tracking, NASA reported Tuesday.
-- the Greenland land mass is second only to Antarctica for its volume of ice --
-- Its not just the Temperature. The Radiation particles in the air from Nuke releases settle in to the ice while they continue to react causing accelerated MELTING. These particles last a very, very long time and continue to accumulate and accelerate the ice melting over time as well.--
Scientists found that the melting had spread quickly - from about 40 per cent of the ice sheet on July 8 to about 97 per cent four days later.
NASA has released color-coded maps showing the dramatic change between July 8 and July 12.
Areas in dark pink show where two or three satellites found evidence of melting. Areas in light pink show where one satellite found evidence of melting.
Greenland has seen an unusual weather pattern since the end of May.
The extreme melting coincided with the last of a series of strong ridges of warm air, described by NASA as 'heat domes'.
Thomas Mote, a climatologist at the University of Georgia, said: 'Each successive ridge has been stronger than the previous one.'
