I agree, we don’t know what the heck we are doing.

Unfortunately we have been conducting a massive intervention in our climate for some time. The lag time is such that we are only seeing clear results that we are the ones causing some effects now, after a quarter century of study.

By all means we should try and quit this experiment before we start adding others into the mix. Hopefully that will be enough.
But …

We won’t know until really bad things start happening. And the lag time is such that if we we don’t do something drastic when the really bad things start, then by the time we get our “desperate climate control experiment #2” up and running things will be really really bad.

Now for you or me, that probably isn’t going to matter. Unless they come up with longevity treatments we are going to check out around the time the really bad things are expected to start showing up.

But if even the conservative CO2 pundits are right (if the non conservative projections are right it’s already too late,) then unless we do everything right over the next 20 years, then the people who are planning to be alive in the later part of the 21st century will have no option but to consider a choice between risky climate control experiments or dealing with billions of hot hungry and thirsty climate refugees.

The whole point of limiting CO2 was never to stop global warming, but to put off as long as possible having to make that unpleasant choice.
