Putting it in black and white 'climate change' versus 'no climate change' is totally the wrong way to frame this. Every degree that the climate warms up is generally going to be worse than the last. The first half degree of warming we experienced from the start of the industrial revolution to the late 20th century was probably a net boon for humanity. The half degree from 1.5 to 2.0 C will flood many inhabited islands and displace hundreds of thousands of people. Past that you will eventually get to millions dying in heat waves.

There's no way to prevent any global warming, because some has already happened. Realistically, we're probably going to see those small island nations flood. But we can still work to prevent things that are even worse and that's worth doing.
