Tipping Point

Scientists are warning we may reach a tipping point for Greenland' ice sheet melting.

They urged governments to be more aware of "tipping points" in nature, tiny shifts that can bring big and almost always damaging changes such as a melt of Arctic summer sea ice or a collapse of the Indian monsoon.

"Society may be lulled into a false sense of security by smooth projections of global change," the scientists at British, German and U.S. institutes wrote in a report saying there were many little-understood thresholds in nature.

Personly I think we passed the tipping point and should be moving to high ground. But, what do I know?
