Anomalocaris Posted August 19, 2015 #1 Share Posted August 19, 2015 Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth's oceans had undergone 1,800 years of a steady cooling trend, according to a new study. During the latter half of this cooling period, the trend was most likely driven by large and frequent volcanic eruptions. 1,800 years of global ocean cooling halted by global warming 1 Link to comment Share on other sites More sharing options...
Ashotep Posted August 19, 2015 #2 Share Posted August 19, 2015 That doesn't sound good. If I understand this correctly even if we clean up our act imediately, stop polluting, the earth will keep warming for a while because of the ocean absorbing so much heat from global warming.

Harte Posted August 19, 2015 #3 Share Posted August 19, 2015 The flip side is, if we hadn't, we'd be in another ice age. Harte Link to comment Share on other sites More sharing options...
TonopahRick Posted August 19, 2015 #4 Share Posted August 19, 2015 Well right now with summer dragging along and the temps in the hundred + degrees area for about 80 or 90 days here in the desert I'll vote for another ice age. 1 Link to comment Share on other sites More sharing options...
Doug1029 Posted August 20, 2015 #5 Share Posted August 20, 2015 The flip side is, if we hadn't, we'd be in another ice age. Harte Without human-caused global warming, the next ice age would still be 8000 to 10,000 years away. The Milankovitch Cycles don't line up so as to create an ice age at this time (At least two of them have to get together at the same time and that didn't happen this time around.). With humans in charge of the climate, there will never be another ice age. We know how to warm the planet. The output of one CFC plant could do it. What we haven't figured out is how to cool it.

Guest Br Cornelius Posted August 21, 2015 #8 Share Posted August 21, 2015 Ocean cooling for 1800 years seems to say differently. Harte We have been cooling as a planet ever since the last post ice age bounce which represents around 8000years of cooling. It was still going to be at least as long again before we re-entered an ice age all other things been unchanged. Geological processes are glacially slow and the minimum time period for a Milankovich cycle is 20thousand years. Br Cornelius Link to comment Share on other sites More sharing options...
Harte Posted August 21, 2015 #9 Share Posted August 21, 2015 Opinons, obviously, differ, but: But as a matter of scientific curiosity, it’s worth noting that “increased glaciation... would probably be happening today” if humans weren’t here, said John Kutzbach, a climate modeler at the University of Wisconsin-Madison. The theory is reminiscent of another recent piece of research, suggesting a bout of global warming may have kept Earth from totally freezing over hundreds of millions of years ago. Only now, researchers, say, something similar could be happening today. The controversial idea—first proposed by University of Virginia climatologist William F. Ruddiman—is based on the contention that human-induced global warming started long before it’s generally accepted to have begun. Source Of course, "increased glaciation" doesn't necessarily mean a full-blown Ice Age. Harte Link to comment Share on other sites More sharing options...
Doug1029 Posted August 21, 2015 #10 Share Posted August 21, 2015 Ocean cooling for 1800 years seems to say differently. Harte Ice sheets ebb and flow with the climate. Minor fluctuations occur all the time. What I am talking about is something like the Wisconsin Ice Age with two miles of ice cover and glaciers reaching to the Ohio River.
