Giant earthquakes are shaking Greenland — and scientists just figured out the disturbing reason why

If Greenland goes, it is becoming clear that it won’t go quietly.

Scientists have already documented entire meltwater lakes vanishing in a matter of hours atop the vast Greenland ice sheet, as huge crevasses open beneath them. And now, they’ve cast light on the mechanisms behind another dramatic geophysical effect brought on by the rumbling and melting of this mass of often mile-thick ice: earthquakes.
