We are in a mass extinction. It is not civilization ending.

Can you explain why you think these contradict each other?

Mass extinction is not necessarily civilization ending. Half of all living species could die, 80% of all humans could die, and civilization would find a way to move on. It would still be an absolutely major catastrophic event.

At the rate that temperature is increasing, assuming it is not stopped, it's not a matter of will there be an extinction event within the next few hundred years, but how bad will it be.

Of course, but why would it matter unless it affects human civilization? There have been extinctions for the history of the world...
