You dont. You are the one moving not climate change. You are almost surely not eligible to be able to solve it.

You can get to better climate, some places can get consequentally colder actually. Historically there are safe havens as well.

You can also try moving up the hierarchy and make it affect your life less. It might be hard for most people, but it is kind of achevable for you. You will be less prone to the effects of climate change.

I never said you help others.
