I don't think it's fair to compare it to before it was habitable by humans. Whenever someone brings up the topic of climate change, it's to discuss the changes making the world less habitable for present day living beings.
Unfortunately it makes it that much harder to fix the problem. Now we have to fix the problem and convince the deniers that it's a problem . Which is close to impossible since the more evidence they see the more they will try to normalize it.
I'm not worried because earth and life will be fine despite our trashing the planet. However to claim that things are extraordinary discounts historical records, even back a few million years.
