Decreased carbon dioxide formed Antarctic ice sheet?

New York, July 31 (IANS) Turning a long-held climate shift theory on its head, researchers have found that decreased carbon dioxide (CO2) levels during a major climate shift 34 million years ago led to initiation of Antarctic glaciation. The finding counters a 40-year-old theory suggesting massive rearrangements of the Earth's continents caused global cooling and the abrupt formation of ...

Ocean currents behind change in ice ages?

Washington, June 29 (IANS) Climatologists have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. Deep ocean currents that move heat around the globe stalled or may have stopped at that time, possibly due to expanding ice cover in the orthern Hemisphere, says a study. The research i...
