A paper from a paleoclimatology workshop finds that the southern dome of Greenland did not melt away during the extreme natural climate change of the “Eemian interglacial (125,000 years ago), when annual mean temperatures over Greenland were [about] 5°C warmer than now for some millenia [thousands of years].”
The author asks, “will [the southern dome of Greenland] melt away for the first time in 400,000 years?” and concludes, “Probably not.” The IPCC claims [non-existent] positive feedback from water vapor could lead to 3°C warming from doubled CO2 levels, but lessons from the geological past show that even if the globe warmed 2°C more to 5°C warmer than the present for thousands of years, neither the northern nor southern domes of Greenland would melt away.
darn that pesky data……
People do not have any concept of the mass of the Greenland Ice Domes. This lack of perspective leads to a total misunderstanding of how long it would take for such a mass of ice to melt, even if all of the sunlight that strikes the earth were used solely for the melting process. Run some numbers of your own, and then sleep well knowing Greenland will be anything but “green” for the next few millennium.
