Next Ice Age Delayed by Rising Carbon Dioxide Levels

Ice SheetIce ages occur about every 100,000 years due to changes in Earth orbit and its effect on the receipt of solar radiation. When the Earth moves into a glacial period also depends on changes to the carbon dioxide content of the atmosphere. Though the Earth system is apparently undergoing significant changes due to global warming, it is considered to be in an interglacial period. Recent work from the University of Southampton’s School of Ocean and Earth Science at the National Oceanography Centre, Southampton seems to indicate that rising carbon dioxide levels driving global warming will delay the next ice age. Interestingly, this research was started by an undergraduate student and expanded upon by Dr Toby Tyrrell and colleague Professor John Shepherd.
