Climate experts said 350 PPM CO2 is the tipping point, beyond which we were doomed. That was passed in 1988
Then they said 400 PPM was the tipping point, beyond which we were doomed. We passed that a couple of years ago.
Now they say 450 PPM is the tipping point, beyond which we are doomed.
I prepared this graph of record daily maximum temperatures in the US since 1895 to help people visualize these tipping points.
We may all freeze to death – if we keep overheating the atmosphere like this.
