Global Warming on Free Republic

A new study using historical images of glaciers in southeast Greenland to investigate glacier response to climate changes suggests that the recently observed acceleration of ice loss from Greenland may not be a long-term phenomenon. Instead, as marine terminating glaciers reach their grounding line and as the termini of land-terminating glaciers migrate upwards in elevation, ice loss rates from glacial discharge may slacken. According to Anders Bjørk and co-researchers:
[T]he recent high rate of retreat may come to a slowdown when retreating marine-terminating glaciers reach their grounding line and become less sensitive to the influence of ocean temperature, or through positive or negative feedback mechanisms relating to the cold East Greenland Coastal Current.
and,
Our results have implications for future estimations of sea-level rise as retreat rates for marine-terminating glaciers are likely to increase as temperature rises until glacier fronts reach the grounding line, or when cold ocean currents re-establish, whereas retreat rates for land-terminating glaciers are not likely to rise in the same order of magnitude.
Such results throw a bit of cold water on alarmist ideas that rising temperatures will lead to ever-accelerating ice loss from Greenland and accelerating sea level rise.

fyi
1930s photos show Greenland glaciers retreating faster than today ( it was no big deal then)

As for extrapolations and such, remember what Mark Twain said:
“In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period, just a million years ago next November, the Lower Mississippi River was upwards of one million three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing-rod. And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen. There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.”

Dinosaurs didn't die off. They simply took canoes and paddled to the moon.
Thanks Ernest.

I read these things, I think to myself that this is common sense, I am not a genus but it is freaking obvious
The assumptions these people are making are stupid beyond belief.
