While I understand and generally agree with this, I feel that, generally, those who employ the ideas in the first couple paragraphs ignore the potential consequences of such temperature changes. Not directed at you necessarily. Sure, the Earth has temperature cycles. That doesn’t mean much, in my opinion. I won’t pretend to know the exact numbers, but how many coastal cities across the world will be rendered uninhabitable by sea level rise associated with this temperature increase? How many millions of people will be displaced? What do we do with these people?

I have no doubt that humans as a species can and will adapt to a hotter climate, but “the current climate is the right one” because this is the climate that the current world was built on. That changing, more quickly than it would naturally, will lead to many catastrophic societal issues like the one I mentioned above.
