Re: The worst case scenario
in thread The worst case scenario
In fact, some of the ice in Antarctica is thickening, despite the accelerating outflow elsewhere. It's a phenomonon that's not satisfactorily explained today. But I'm not aware (and it's part of my business to be so) of *significant* increases anywhere else; not in the north, nor in extreme Alpine regimes.
And while there's considerable evidence for disparate climatic change, S. vs N, it's very clear that the 'cap in Greenland -- home to a huge proportion of the northern hemisphere's frozen water -- is undergoing as much or more melting each year (over the past 8-15 for certain) than anytime in the historic record in our cores. Further, it's starting to look as though open water is more widespread and, for any given location, earlier, throughout the Arctic and, while data is *VERY* spotty, that ice-thickness is decreasing precipitously.
All that said, TedPride's apocalyptic concerns with rocks and nukes may be better justified than any Hollywood scenarios giving us glaciers rushing south at highway speeds...
