A new topographical reconstruction of the land mass beneath Antarctica may, for the first time, let [geologists] glimpse into our possible future. A warm, frightening future.
The British Antarctic Survey created Bedmap2, a detailed map of the terrain beneath the icy sheets of the South Pole. The permanent ice on our polar continent is fluid, mobile, and sensitive to our changing climate. Understanding its relationship to the Earth beneath it is crucial to predicting whether of our warming planet allows it to maintain its solid form, or if some of it could wash away into rising seas.
