The Atlantic current during the Ice Age – and melting ice sheets

5 November 2010

At www.sciencedaily.com/releases/2010/11/101103141541.htm (see also http://news.yahoo/livescience/20101103/sc_livescience/atlantic ) there is a report on an article published this week in Nature which claims that during the Late Glacial Maximum the flow of deep waters in the Atlantic differed to what happens today. It was extremely cold at that time but strangely this has not stopped AGW fantasy from suggesting the same thing will happen as the climate warms in the coming years. Quite how this might happen is unclear as in the climate models the Polar Front and the Jet Stream are destined to move northwards as the winter weather retreats whereas in the Ice Age the Polar Front was as far south as northern Iberia and the Jet Stream likewise – exactly the opposite situation. However, the AGW hype comes with the press release and is a required fillip in order to obtain future funding for research and is therefore somewhat superfluous. The real science is in the research of sea floor sediments in demanding conditions in the Southern Ocean, 2.5 km deep. This indicates the ocean circulation system dffered remarkably to how it now operates. The question is why?

In another study (see www.sciencedaily.com/releases/2010/11/101103171702.htm ) melt water flowing through crevasses, fractures in the ice, and what are called moulins are said to be capable of carrying warmth into the interior region of ice sheets and glaciers which it is said will accelerate the thermal response to climate change. Global warming to the unwashed. Hence, ice sheets will collapse more quickly. The research is published in Geophysical Research Letters but again it is worthwhile ignoring the AGW funded references as the authors say the Greenland ice sheet is not under threat and it will still take thousands of years to melt – even if global warming was real.
