Yeah its negative, it comes from Earth, not to Earth. Using it has a cost, to Earth, like any other energy we've taken from Earth. How will you put it back, after that cost is realised?

Notice everything I've written about, is how to put back what we used already. That is the only way we will get the temperature back down. We have to go photosythetic, like all the photosynthetic nature we removed already, to remove our depdendence from it, to allow it to recover. CO2 is just a multiplier of that root cause, not the cause of anything itself.
