“The glaciers of Pine Island Bay are two of the largest and fastest-melting in Antarctica. … Together, they act as a plug holding back enough ice to pour 11 feet of sea-level rise into the world’s oceans—an amount that would submerge every coastal city on the planet. For that reason, finding out how fast these glaciers will collapse is one of the most important scientific questions in the world today.”
Hyperbole in the title. But an article well worth reading.
