Climate change is going to introduce new terminology to our lexicon.

Pyro-cumulonimbus is probably one of these new terms.

It's been a term for a long time. Do you mean in general usage?

Yes. It’s not a term that I’ve ever heard before.

I guess it's like "polar vortex"

Yes. I think “megafire” is another one. These are all very sobering terms.
