[QUOTE="Old Man Jingles, post: 4362824, member: 18222"] I agree with all that but the interruption of thermohaline circulation normally results in regional climate disruptions with [B][COLOR=#0000b3]no increase in temperature and in fact, the opposite.[/COLOR][/B] [SIZE=6][B][URL='https://phys.org/news/2004-12-shutdown-circulation-pattern-disastrous.html']Shutdown of circulation pattern could be disastrous, researchers say[/URL][/B][/SIZE] Paleoclimate records constructed from Greenland ice cores have revealed that the thermohaline circulation has, indeed, shut down in the past and caused regional climate change. As the vast ice sheet that covered much of North America during the last ice age finally receded, the meltwater flowed out the St. Lawrence and into the North Atlantic. “The additional fresh water made the ocean surface less dense and it stopped sinking, effectively shutting down the thermohaline circulation,” Schlesinger said. “As a result, Greenland [B][COLOR=#0000b3]cooled by about 7 degrees Celsius within several decades[/COLOR].[/B] When the meltwater stopped, the circulation pattern restarted, and Greenland warmed.” [/QUOTE]
