"The fundamental problem is that the earth was in a balance,"

Nit pick but, is there anything that says the earth isn't or won't be at a balance?

Sure, climate change will be hugely impactful, especially for humans, but I figure the earth will still be in balance, just not the one we are used to.

Historically huge swings in climate did occur, they also often coincided with catastrophic extinction events. Forgive me for not caring that the warmer Earth is newly “in balance” for whatever heat-loving species emerge.

Venus and Mars both found their own kinds of balance. As far as we can tell, balances that favor life are rare.

I'm not arguing the point you're arguing against, but I felt the need to point out that those two extremes are not what we are talking about, we are talking about a new "balance" that is known to have supported life in the past.
