Now, fossils of ocean algae reveal that a weakening in upwelling in the Antarctic Ocean kept more CO2 in the deep ocean during the ice ages. This brings scientists closer to a complete explanation for the glacial cycle and suggests that upwelling will strengthen under anthropogenic global warming, altering global climate and ocean ecosystems.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/www.sciencedaily.com\/releases\/2020\/12\/201210145757.htm\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">What caused the ice ages?
