Even mild global warming could completely melt Greenland’s ice cap


Not to worry however.

At least not for a few thousand years.

That's according to a research study by
the Potsdam Institute for Climate Impact Research (PIK)
and the Universidad Complutense de Madrid.

The Raw Story

The Greenland icesheet is more sensitive to global warming than thought, for just a relatively small — but very long term — temperature rise would melt it completely, according to a study published on Sunday.

Previous research has suggested it would need warming of at least 3.1 degrees Celsius (5.6 degrees Fahrenheit) above pre-industrial levels, in a range of 1.9-5.1 C (3.4-9.1 F), to totally melt the icesheet.

But new estimates, published in the journal Nature Climate Change, put the threshold at 1.6 C (2.9 F), in a range of 0.8-3.2 C (1.4-5.8 F), although this would have to be sustained for tens of thousands of years.

Greenland goes Green



But...

Current carbon emissions, though, place warming far beyond this objective. If they were unchecked, a fifth of the icesheet would melt within 500 years and all would be gone within 2,000 years, the study says.

Now that's called melt off eh,maybe it will flash freeze again?

my geography teacher told me last year the ice caps would melt within about 20 years...

apparently there in a virtually irreversible cycle and losing mass each and every year

and the more that melts the more water there is to absorb heat (more than ice would) and the process is only going to speed up...

These quack's are playing chicken little.They need to return to pre-school and ponder why Greenland was called green!
