"When people think about the risks of climate change, the idea of abrupt
changes is pretty scary. Movies like “The Day After Tomorrow” feed that fear,
with visions of unimaginable storms and populations fleeing to escape rapidly
changing temperatures.
While Hollywood clearly takes liberties with the speed and magnitude of
disasters, several recent studies have raised real-world alarms that a crucial
ocean current that circulates heat to northern countries might shut down this
century, with potentially disastrous consequences.
That scenario has happened in the past, most recently more than 16,000 years
ago. However, it relies on Greenland shedding a lot of ice into the ocean.
Our new research, published in the journal
Science, suggests that while
Greenland is indeed losing huge and worrisome volumes of ice right now, that
might not continue for long enough to shut down the current on its own. A
closer look at evidence from the past shows why."
