CO2 9-26% (I guess that depends on whether Algore is speaking that day),

Ranges depend on the spectral overlap. The issue of whether doubling CO2 causes catastrophic warming or not depends on that overlap plus the changes in weather that may occur at higher temperatures. Because of the overlap with H2O, the doubling of CO2 creates about a 0.25C temperature rise, not catastrophic. Factoring in weather changes, there may be a rise in the height of the troposphere or other changes that cause warming. Real world measurements are not conclusive but it is doubtful that there would be enough positive feedback to be considered catastrophic.

The academics is interesting, but the alarmism is both juvenile and fraudulent, even criminal.

There is nothing man can or should do other than be aware. Just like incoming meteors.
