There is zero evidence that a warming planet would case a systemic collapse in biodiversity. In fact, 500 millions of planetary history shows the opposite. As the planet warms, biodiversity increases. There is nothing to argue about here.

And again, you are confused about timeframes. Geologic time vs human time.

Sure, over a period of millions of years, everything evolves and adapts. But in shorter periods of time, before adaptation, there is enormous disruption and entire ecosystems go extinct. Taking countless species down with it.

Human civilization has been around for only a few thousand years. You do the math. As you say, nothing to argue about here.

sans-humans, maybe. But we /are/ causing the Holocene extinction, which is essentially defined by the last two centuries of accelerated biodiversity loss. Climate change will only further stress already fundamentally strained ecosystems. It’s happening right now, at all of our literal doorsteps.
