I think there’s maybe more risk with the solar system being thrown off balance with other gravitational forces pulling things out of orbit. Even if earth just gets pulled away from the sun a little we are screwed. Or even the moon pulled away from earth somewhat.

I get what you’re saying, but had to laugh at the use of “a little” here. The goldilocks zone in the solar system is roughly the between the orbits of Venus and Mars, and we’re almost right in the middle of it, so “a little” is like 150 million km.
I would imagine that the first issue we would experience would be that the moon would be pulled out of Earth’s orbit first and then we lose the ocean tides and the stable tilt of the earth. It would probably get worse from there.
Goldilocks zone is basically just where life can survive.
Even if we stay within the Goldilocks zone doesn’t mean that most of the species alive today won’t go extinct because it fucks up the seasons or the magnetic poles or tilt of the earth, etc.
It’s even safer. The odds that it’s coming directly at us to “collide” is low. Moving towards us doesn’t mean it’s moving directly at us. If you’re driving down the road, all cars going in the other direction get doppler shifted. They’re coming towards you, they pass beside you (hopefully), and then they’re moving away from you.
Eh, the odds of actually colliding with anything is low enough. Plus the night sky would probably be even more breathtaking. I’m in

Maybe we’ll get lucky and it’ll counter global warming
“Thank god global warming never happened.”
“Actually, it did, but thank god for nuclear winter.”
Just keep scooting away a little every year, problem solved
Could the other galaxy please pull us just the correct distance away from the sun to cancel the effect of global warming?
Given the vastness of space, this is a lot less likely than you might think, and the process itself would likely take millenia anyway.
and lose the character of the spiral arm configuration? For what? A blob??
