Where will the new East Coast shoreline be?
COPENHAGEN -- Months before make-or-break climate negotiations, a conclave of scientists warned Tuesday that the impact of global warming was accelerating beyond a forecast made by U.N. experts two years ago.Sea levels this century may rise several times higher than predictions made in 2007 that form the scientific foundation for policymakers today, the meeting heard.
In March 2007, the U.N.'s Intergovernmental Panel on Climate Change concluded that global warming, if unchecked, would lead to a devastating amalgam of floods, drought, disease and extreme weather by the century end.
The world's oceans would creep up 18 to 59 centimeters (7 to 23 inches), enough to wipe out several small island nations and wreak havoc for tens of millions living in low-lying deltas in east Asia, the Indian subcontinent and Africa.
But a new study, presented at the Copenhagen meeting on Tuesday, factored in likely water runoff from disintegrating glaciers in Greenland and Antarctica, and found the rise could be much higher.
