No Quick Fix for Global Warming in Greenland
The warming that humans cause today may have ripple effects far into the future, scientists warned in a study yesterday that finds the vast Greenland ice sheet could continue melting for centuries after greenhouse gases are stabilized. Greenland has a delayed response to changes in the Earth’s climate, and even if the planet stopped warming tomorrow, Greenland may continue losing ice for hundreds or even thousands of years.
During periods of natural cooling, for instance, the ice sheet has begun to grow—and then it continued to grow for some time even after the climate starts warming again. Eventually, the ice sheet flips and starts to shrink again. Then it continues shrinking even after temperatures stop rising.
That’s because the Greenland ice sheet is such a large, complex system. The ice sheet is so large that once it starts losing ice at faster and faster speeds, it can take a long time to slow back down again.
