I wouldn't call it totally impossible, just impossible under capitalism. Terraforming isn't a good solution for climate change though, it's too slow to reverse the massive damage we've already done. In order to reverse climate change we simply need to cease CO2 producing activities. Any terraforming we'd do would just produce more CO2 than it could absorb.
Terraforming is typically thought of as occurring over much longer time scales, like centuries to millennia. It takes a communist society to commit to a project like this where there is no immediate short term profit. Terraforming Mars is an admirable goal to have, but only after we get our shit together here on Earth.

That is likely too late to work as many feedback loops are likely to have already been triggered, or will be due to the eventual heating from the CO2 we already emitted.
Yeah there's definitely a ton of damage baked in. I guess by reverse, I really meant to say eventually stop. It'll take time for the temperature to stop rising even after we quit pouring CO2 into the atmosphere. But still, that is pretty much the only tool we have beyond something drastic like filling the upper atmosphere with light reflecting particulates.
