> How does the COVID response have anything to do with the climate response? The governments of the world have all responded differently -- some quite stringently -- and the speed with which we produced an mRNA vaccine (itself a technological marvel) is truly nuts.

I read the point as that now we've seen what governments around the world are willing to do when they perceive a real emergency: Shut down entire industries, print money to subsidize everybody, and enforce exceptions for rent/debt payments for people affected. There has as yet been no willingness to take anything of the sort in response to climate change.
