Key couple of paragraphs from Joh Hardly's 7:46 AM link:

"Modelling studies of the Greenland Ice Sheet mass balance under greenhouse global warming have shown that temperature increases up to about 3ºC lead to positive mass balance changes at high elevations – due to snow accumulation – and negative at low elevations – due to snow melt exceeding accumulation.

****Such models agree with the new observational results. However after that threshold is reached, potentially within the next hundred years, losses from melting would exceed accumulation from increases in snowfall – then the meltdown of the Greenland Ice Sheet would be on.****"

Emphasis added by TIA. Rush Limbaugh (among others) has trumpeted this accumulation zone thickening as proof that the shrinking ice caps are a fraud. As this article makes very clear, this thickening is actually conistent with global warming models.

As in all things, carefully selected data can be made to show just about anything. Always check the context.
