Greenland meltdown could happen in only 67,000 years!

The Hockey Schtick
"A 'Scientific' American article, Greenland Meltdown Driven by Collapse of Glaciers at Ocean Outlets, begins with the scary proclamation, “the ice sheet as a whole has lost some 36 billion metric tons of ice each year in recent years.” However, the New Zealand Climate Conversation Group calculates this amounts to an annual loss of only 0.00148% of the Greenland ice cap and would require only 67,222 years to meltdown at that rate [if an ice age doesn't occur beforehand]."
