Melted Sea Ice Absorbs Carbon Dioxide Offsetting Some GW Impact
UPI Correspondent Kingston (UPI) Jan 08, 2007 Melting Arctic sea ice allows the ocean to absorb carbon dioxide from the atmosphere, offsetting some global warming effects, scientists said in Jamaica. Ice melting during the last 30 years tripled the amount of carbon dioxide the Arctic Ocean can absorb, New Scientist said Monday. A research team lead by Nick Bates of the Bermuda Institute of Ocean Sciences calculated carbon dioxide absorption in the Arctic Ocean by taking measurements in the Chuckchi Sea and Canada basin in 2002 and 2004. They found the carbon dioxide uptake from the atmosphere increased dramatically during the summer months, when sea ice was at a minimum. "Sea ice acts as a barrier to gas exchange," says Bates. Overall the team calculated that the entire Arctic Ocean is capable of absorbing up to 66 million tons of carbon dioxide annually -- more is possible if the sea ice melting continues. However, the amount won't balance global warming. Currently worldwide carbon dioxide emissions are over 30 billion tons a year.

Climate Chief Seeks UN Summit To Invigorate Global Warming Action
Paris (AFP) Jan 08, 2007The top United Nations official on climate change said on Monday he would ask new UN boss Ban Ki-moon to show true leadership and host a summit to breathe life into sagging efforts to fight global warming. Yvo de Boer, executive secretary of the UN Framework Convention on Climate Change (UNFCCC), said he would make the pitch when he went to New York next week to meet the UN secretary general, who took office on January 1. |
