Will we have colonized the solar system and left earth to stabilize itself

Definitely not that. Any technology that would allow us to colonize other planets would be much easier to use on Earth no matter how bad it gets.

It can also be argued that the continued trend of having an increasing human population is only going to keep accelerating the decline of earth’s biosphere.

We’re already seeing an apocalypse in the insects, and that’s going to lead to a decline in plant life.

Our carbon emissions are rapidly increasing ocean acidity and temperature, which will kill off huge swaths of the planktons that produce much of the oxygen we breathe. Biodiversity is approaching mass extinction level lows, and we’re barely figuring out how to slow it down.

I’m sure life on earth will survive it, it survived the impact that killed the dinosaurs, and that was an incredibly rapid change. But human civilization as we know it may not be able to adapt quickly enough to the damage we’ve done.

Humanity may end up as mole people living in carefully life support controlled bunkers if we continue. If earth is nearly as inhospitable to large terrestrial life as mars, what’s the benefit to one over the other? Might as well just leave the earth to the million year process of fixing itself and expand outwards if we can.

Earth still has plenty of benefits:

  • Things will grow outdoors, even if they're not the things we want growing.
  • We already know where major deposits of natural resources are.
  • There's an ionosphere, meaning the surface isn't bathed in deadly radiation.
  • Parts of it, such as the poles, will likely remain habitable.

The big issue, though, is that transporting any substantial number people to Mars would require many trillions of dollars of investments in space transportation. It's just not feasible to ship a large number of people to another planet. Even if we could start a colony on Mars, most of humanity will still be stuck on Earth and they won't have much interest in supporting a colony on another planet if they're being left to die.

The thing is that even with catastrophic global warming, earth would still be tons more habitable than Mars. Any structure that could allow survival on Mars would also allow survival on this hypothetical future earth.

We either fix it or we are screwed. So we are probably screwed. Anyone seeking to build a Mars colony as an "escape" would probably fare better building similar stuff in earth deserts, or something somewhat different underwater. Still not the most sane places to go for, but more sane than Mars if the goal is "most survivability".
