Global Warming: Natural Causes #8

From this post:

The cry of imminent doom due to global warming and citing the Arctic Sea ice melts as a major symptom when records have only been kept for less than four decades is rather disingenuous. Add to that that the global warming loons have yet been able to explain where all the ice on the Greenland ice sheet came from over the 50 year period from 1943 to 1993 when efforts to recover WW2 aircraft forced done on the ice sheet had to bore through nearly 300 feet of ice that had formed over the site.
