WASHINGTON - The Arctic will remain on thinning ice, and climate warming is expected to begin affecting the Antarctic also, scientists said Friday.
"The long-term prognosis is not very optimistic," atmospheric scientist Jennifer Francis of Rutgers University said at a briefing.
Last summer sea ice in the North shrank to a record low, a change many attribute to global warming.
But while solar radiation and amounts of greenhouse gases in the atmosphere are similar at the poles, to date the regions have responded differently, with little change in the South, explained oceanographer James Overland of the National Oceanic and Atmospheric Administration.
