Either way, we have 380 parts per million of carbon in the atmosphere. 350 is the tipping point. We were there about 10 years ago. If we don't get back to 350 soon, we won't be able to stop the harm.

Millions of years ago, the CO2 was at one point, almost 4000 ppm which is over 10x what it is now. Nothing tipped back then. Nothing is going to tip now or in the near future from higher CO2 levels.
