The problem with that notion is the assumption that we *can* do something

dimmer switch on the sun?

Actually, it's not totally out of the question. Theoretically you could
put one or more large mirrors between the earth and the sun and maybe
even use the reflected light for a power-generation plant.

Yes, I'm familiar with the idea. But if it was practical... it woulda been
done already.

I would first argue that the current changes in climate are only
slightly dependent on the observed changes in solar output,

....but treating the question as hypothetical, and accepting that you can't
prevent it, you continue to study climate and predict what the changes
will be, so that you have time to prepare and adapt. If you're lucky,
there won't be much to do, but if the changes are significant and costly,
an early start will help.
