Yea I just don't care about any of that and I don't think that's wrong.
Nth order effects will make it your problem pretty quickly.
Many are blind to exponentially growing phenomena.
One good example is that a several degree increase can melt the Siberian ice and release methane stores equivalent to 100 years of maximal human CO2 footprint. That's already a massive nth order effect.
Sometimes problems are not that simple.
I’m pretty sure he would also agree with the estimate for Siberian methane stores. He would just be careful with predicting what happens when they get released.
The average temperature increase can have different effects and that is one of the lines of his argument.
If you do not care about the issue and don’t want to hear opposing opinion then do not leave a comment.
