Massive Greenland meltdown? Not so fast, say scientists

Two were based on changes caused directly by global warming: an increase in the amount of water that greases the underbelly of the glacier as it slides toward the sea, and a general thinning due to melting.

If confirmed, either of these explanations would point to a sustained increase in runoff over the coming decades, fueling speculation that sea level could rise faster and higher than once thought.

The stakes are enormous: the rate at which the global ocean water mark rises could have a devastating impact on hundreds of millions of people living in low-lying areas around the world.
