Short video explaining climate change tipping points

Mainstream climate models don't (and can't) include tipping points in their model, as they are too complex and uncertain. Their existance is known, but their magnitude and exact trigger is a bit up in the air. This video does a great job of clarifying what they are and conveys a sense of how much more urgent they make taking action on climate change.

The video uses +1.4 degrees as the level where tipping points start to be a factor. I thought it was +2.0 degrees, but even if I'm right I doubt that gives us much more breathing room.
