New York Times - For half a century, climate scientists have seen the West Antarctic ice sheet, a remnant of the last ice age, as a sword of Damocles hanging over human civilization.
The great ice sheet, larger than Mexico, is thought to be potentially vulnerable to disintegration from a relatively small amount of global warming, and capable of raising the sea level by 12 feet or more should it break up. But researchers long assumed the worst effects would take hundreds - if not thousands - of years to occur.
Now, new research suggests the disaster scenario could play out much sooner.
Reuters - This could spell disaster for many low-lying cities, lead author Robert DeConto at the University of Massachusetts, Amherst, said in a statement of the findings published in the journal Nature.
For example, Boston could see more than 1.5 meters [5 feet] of sea-level rise in the next 100 years.
