To me, there are two reasons we're doing it too soon;

  • We don't really have technology needed to build a self-sustaining colony anywhere outside Earth; say, a colony on Mars is inherently dependent on Earth's supplies, and will quickly die out as Earth does too; the technologies needed can largely be developed on Earth;
  • The chance of some asteroid obliterating Earth in the coming millenia is so minor we might as well focus on much more real threats.

Yeah, every time I see someone say go to Mars as an answer to the earth getting ruined, have to keep in mind that Mars is pre ruined, and whatever calamity that ruins earth will be easier to survive than colonizing Mars

Exactly

Or those "terraform Mars" fantasies

TERRAFORM THE DAMN EARTH FIRST

It's not a zero sum game. I'd rather keep space research going to lower the risk as fast as we can. If you want to focus on the climate then we should end fast fashion which is much much worse for the environment. Also, space colonies are a chicken and egg problem, you cant just wait until the tech magically appears, you have to spend money inventing it. [Insert famous JFK quote about going to the moon here]
