LONDON (Reuters) - Governments could stop the West Antarctic Ice Sheet from sliding into the ocean and submerging coastal cities by launching a last-ditch engineering project to blanket its surface with "artificial snow", according to a study released on Wednesday.
Scientists believe that global warming has already caused so much melting at the south pole that the giant ice sheet is now on course to disintegrate, which would trigger an eventual global sea level rise of at least three metres (10 feet) over centuries.
