That's a very silly question. Of course nobody wants the Earth to heat up, but you have a couple options to stop it.
1. Cease almost all production of goods
2. Keep going and develop tech later
The first would destroy many nations struggling to create wealth, and it will capitulate already existing nations. You'd have nothing left to save, it would just be a bunch of dead people and tribes fighting over cans of SPAM. That's a bit of a hyperbole, I know, but the idea is funny.
Then the second is just stuff like this. We'll find a way, and if it rises a little bit, we'll find a way to cool it off. A huge increase in temperatures would be catastrophic, but not apocalyptic.
That is a rather forced dichotomy. I agree it is a problem started by technology and ultimately to be solved by it but in the meantime it might serve to lessen the effects (say less fossil and more nuclear and renewable, still enjoy the same power capacity and resulting quality of life though).
