Global Warming causing more ice in Antarctic
[quote]Climate change is expanding Antarctica's sea ice, according to a scientific study in the journal Nature Geoscience.
The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves.
This melt water has a relatively low density, so it accumulates in the top layer of the ocean.
The cool surface waters then re-freeze more easily during Autumn and Winter.
This explains the observed peak in sea ice during these seasons, a team from the Royal Netherlands Meteorological Institute (KNMI) in De Bilt says in its peer-reviewed paper.[/quote]
Sound's possible....

4 RepliesDoes sound possible indeed. The lower density is caused by the fact that the meltwater has little to no salinity, and because of the low salinity it also freezes much faster. What interests me is how this will affect the Thermohaline Circulation, or Great Ocean Conveyor. It could cut off the little amount of warm water going to the Northern Hemisphere, which could cause an actual Ice Age. Only 10% of the water from the THC is traveling north, so a small change in the THC on the southern hemisphere can have a large impact on Northern and Western Europe and the USA Eastern Seabord.
