For those who believe that the Greenland ice fields are shrinking, here's a completely incidental proof to the contrary.
Basically a squadron of P38 Lighting aircraft ran out of fuel in bad weather over Greenland during WW2, where they all belly landed on the ice cap.
The crews were rescued but all the aircraft had to be abandoned, and remained there till the 80s when some warbird researcher found some documentation of the event. There being no record of recovery of the aircraft, they set out to try and find them.
They were eventually discovered over 250 ft below the surface. Using steam blast equipment they dismantled one of them and it is now flying again as the Glacier Girl.
The point being that the Greenland ice field thickness has not been reducing, but has increased by over 250ft since the war.
