For the past ten years, skyscraper-sized icebergs have cracked off glaciers in Greenland and tumbled into the sea at an ever-quickening rate in response to global warming, raising concerns about runaway ice loss and rising seas. The good news? The rate of acceleration will slow, according to a new study.

The slowdown is related to the physics and geography that govern glacier movement, not a forecast that the rise in global temperatures will halt anytime soon. Indeed, the ice sheets will continue to melt and push up sea levels around the world, just not as quickly as feared, the study’s lead author said.
