What's A Tipping Point?

We hear a bit about the climate's tipping points that we seriously want to avoid. But what exactly is a tipping point. This little video explains the concept and gives a few examples of the feedback mechanisms.


I also like the statement at the end:

Those who came before us didn't know about this problem, and those who come after will be powerless to do anything about it. But for us there's still time. We'd better get a move on though.
