Preferably policy is made based on facts and common sense.
If you’ve ever worked a reasonably complex system I’m sure you’ll agree that minuscule changes or additions can have unforeseen and sometimes devastating consequences.
In large systems of complexity you usually end up with really weird, cascading issues. Things triggering other things, hitting edges etc.
I don’t think I ever worked anything remotely as complex a system as the earth (or... have I?), but looking at the graphs of co2 since the beginning of industrialization it’s quite clear we are making massive changes to a system that have had many thousands of years to get in tune.
Couple this with the fact that almost all experts in related fields seem to agree that the changes we’re seeing will be destructive and also difficult to mitigate you have something that just simply makes sense.
It would be utterly foolish not to make policy of it.

I’d love to hear how the sceptics turn this fact in to present day politics.
Policy seems to be the only way we can sort this future mess out btw.
