Climate Change May Continue for at Least a Millennium

Climate change may be unstoppable for the next millennium.

Rising carbon-dioxide levels in the atmosphere will affect the climate for at least another 1,000 years, based on a simulation by researchers at Canada’s University of Victoria and University of Calgary. That will cause the West Antarctic ice sheet to collapse by the year 3000 and raise sea levels by 4 meters (13 feet), it showed.
