It seems over negative as well. There are a couple of simple things that may help with CO2:

1) Exponential improvements with wind solar and batteries. They are all getting like 50% better / year. Project that and you can fix things

2) Re the confusion over different approaches, we have a solution and its called the market. Just have a global $50/ton tax/credit on emissions/sequestration. Politically hard but otherwise would likely fix rising CO2.
