You're just throwing up arguments to see what sticks here. Almost everything you're saying is wrong or misdirected.

> Never mind that the plants consume CO2.

The linked technique is literally about getting more plants to grow to consume CO2.

> Or that we are wise enough to know what is the correct cooling/heating rate for the planet.

Strawman. You don't have to have a perfect master plan to know that "wildly distorted CO2 levels from the geological baseline of the last epoch" is almost certainly the WRONG level from the perspective of existing ecosystems. You don't need to be able to engineer a perfect wheelbarrow to fix a broken handle with duct tape.

> Or that CO2, is even the right metric at all.

Same deal. It's pretty clearly a metric, and something we're messing up. You're right that there are other greenhouse forcing mechanisms (methane being the big one). That doesn't constitute an argument for "don't fix CO2". You don't skip an alignment appointment on your car because it also has a rattle under the hood.
