North Atlantic Waters Preventing Greenland Ice Melt
Well Whad'Ya know? Despite alarmist cries, it turns out that warming is good after-all and the arctic is doing just fine:
'Hidden Plumbing' Helps Slow Greenland Ice Flow: Hotter Summers May Actually Slow Down Flow of Glaciers
Hotter summers may not be as catastrophic for the Greenland ice sheet as previously feared and may actually slow down the flow of glaciers, according to new research.
A letter published in Nature on 27 January explains how increased melting in warmer years causes the internal drainage system of the ice sheet to 'adapt' and accommodate more melt-water, without speeding up the flow of ice toward the oceans. The findings have important implications for future assessments of global sea level rise.
The study was funded by the Natural Environment Research Council's National Centre for Earth Observation.

Is this natural warming effect that protects glaciers actually happening though? Another recent study also on ScienceDaily suggests that yes, it is:
Warming North Atlantic Water Tied to Heating Arctic
Led by Robert Spielhagen of the Academy of Sciences, Humanities and Literature in Mainz, Germany, the study showed that water from the Fram Strait that runs between Greenland and Svalbard -- an archipelago constituting the northernmost part of Norway -- has warmed roughly 3.5 degrees Fahrenheit in the past century.
and furthermore they report that arctic sea ice decline has been caused by the Atlantic, not by CO2:
"We must assume that the accelerated decrease of the Arctic sea ice cover and the warming of the ocean and atmosphere of the Arctic measured in recent decades are in part related to an increased heat transfer from the Atlantic," said Spielhagen.
Well color me surprised. Looks like nature is just fine and can take care of itself after-all. I've always said we have more to fear from Global Cooling. Now we can add melting ice caps to the list of problems a little ice age would cause.
