In Search of the Climate’s Tipping Point

03/18/2009

When asked to quantify the impact of climate change, scientists come up with a lot of interesting answers, no two of them quite the same. For the lay person, then, perhaps the simplest way to understand it is to imagine a distant asteroid, somewhere out in space, on a collision course with Earth. It’s not clear when or where the asteroid will hit, or exactly how severe the consequences will be. But it is clear that when it happens, the consequences will be far worse — and last far longer — than any natural disaster humanity has ever known.

That is the threat to the planet that many scientists can agree is posed by climate change.
