Sea-level rise is one of the scariest effects of climate change. Over coming decades, scientists say it will put millions of people at risk in the continental United States, not to mention other parts of the world, including large parts of Asia and many Pacific islands.


What’s even scarier is that it could happen a lot faster than we predicted.

In a new study in Nature, published Wednesday, two US climate scientists say that a melting Antarctica could contribute more than 1 meter of sea-level rise by 2100 (that’s over 3 feet), and more than 15 meters by 2500, if we keep pumping out greenhouse gases at current rates. In the worst-case scenario, their model doubles the best estimates of sea-level rise from the UN’s Intergovernmental Panel on Climate Change, predicted over the next century.
