Antarctic melt may push sea levels to 1.4 metres: study http://apocadocs.com/s.pl?1259676340
Quickening ice loss in West Antarctica will likely contribute heavily to a projected sea level rise of up to 1.4 metres (4.5 feet) by 2100, according to a major scientific report released Tuesday.
Scientists long held that most of Antarctica's continent-sized ice sheet was highly resistant to global warming, and that the more vulnerable West Antarctic ice block would remain intact for thousands of years to come.
The Intergovernmental Panel on Climate Change (IPCC) -- whose 2007 report is the scientific benchmark for the UN December 7-18 Copenhagen climate summit -- did not even factor melting ice sheets into its forecasts for rising seas.
But studies since then show huge loss of ice mass, mainly as a result of warmer ocean temperatures, according to the review by more than 100 experts on the Scientific Committee on Antarctic Research.
