Sure, but the broken window fallacy basically just serves to illustrate that there are opportunity costs when we spend resources on fixing something. The benefits we get from these investments are still real, they're just less than what we might have gotten otherwise.

To put it another way - climate change is sure to be a disaster, but if we get better recycling technology, more efficient cars, pollution-free power generation and other improvements as part of the work of fighting it, that's at least a silver lining.
