> Calling every storm a once in a century storm or saying how once a century events now happen every year (you'll hear both of these claims often) does nothing but discredit climate change.

Isn't it the other way? If climate change makes storms more intense, then "(previously) once-a-century storm happening more often than once a century" is precisely what you would expect to see.

I agree that there are too many breathless headlines and not enough scientific rigor, but that happens with any topic, not just climate change.

* Also, nothing can really "discredit climate change" in the same sense nothing can discredit covid-19 or the war in Ukraine. It's happening, we all know it's happening, the most we could argue about is how it would impact the world.
