Warmist spin machine revs up as Arctic fails to melt

Atlantic Canada facing big chill
23 Sep 08 - “Some scientists are cautioning that global warming could mean colder weather for Atlantic Canada.

“Melting Arctic ice may cause cooler water to drift south and change the climate of the eastern provinces in a different way than many people would expect, said Ken Drinkwater, who worked for three decades at the Bedford Institute of Oceanography before moving to the Institute of Marine Research in Norway five years ago.

“The melting Arctic and Subarctic ice would alter a phenomenon known in scientific circles as meridional overturning circulation, where warm ocean currents move north and colder currents move south to help maintain a moderate climate on the Atlantic coast.

"What the melting of the ice means is a real strong freshwater layer near the surface, so the water doesn’t get mixed down or sink. It’s too light."

"It would have a bigger impact in Europe," Mr. Drinkwater said of the cooling theory. "It would affect the northeastern part of the Atlantic a bit more, but there would be ramifications for this area as well.

"It’s really not clear at this stage exactly what will happen."

“Daniel Duplisea, a scientist from Quebec who’s also attending the conference, said the colder water flowing southward from the melted Arctic ice could "for sure" result in a cooler climate on the East Coast.”

22 Sep 08 - An international team of earth scientists reports finding warmed sea water moving through the flat, Pacific Ocean floor off Costa Rica.

Located between 50 and 150 miles offshore, the region studied covers an area the size of Connecticut. The sea floor, some two miles below, contains about 10 widely separated outcrops or mounts rising from extinct volcanic rock beneath the sedimentary crust.

Carol Stein, professor of earth and environmental sciences at the University of Illinois at Chicago and her colleagues found that seawater on this cold ocean floor is flowing through cracks and crevices faster and in greater quantity than typically found at mid-ocean ridges formed by rising lava. Water temperatures, while not as hot as by the ridge lava outcrops, are surprisingly warm as well.

"It's like finding Old Faithful in Illinois," said Stein. "When we went out to try to get a feel for how much heat was coming from the ocean floor and how much sea water might be moving through it, we found that there was much more heat than we expected at the outcrops."

The water gushing from sea floor protrusions warms as it moves through the insulated volcanic rock and picks up heat.

The findings were reported in a letter printed in Nature Geoscience's September 2008 issue. The lead author is Michael Hutnak, now with the U.S. Geological Survey.
