When a "100 year storm" starts happening every 2-3 years and devastating local economies, you can attribute that to climate change.

Unless there are fewer than 100 places, you'd expect at least one 100 year storm somewhere every year.

Well, do you think the parent comment meant 100 year storms anywhere, or did they mean in the same area, based on the context of what they said?

Are we still talking about Katrina? Has New Orleans been hit by five Katrinas since 2005?

They didn't all directly hit New Orleans, but: Ivan, Katrina, Rita, Wilma, and Michael are all cat-5 hurricanes that have hit the U.S. Gulf Coast in the last 20 years. There have been 37 cat-5 hurricanes since record keeping began in 1851; of those, 8 happened during the 2000s and 6 more during the 2010s, so about 37% of recorded cat-5 hurricanes have happened in the last 20 years of this 170-year period.

From insurance rates and lack of investment it would seem like it (I live here)

Hopefully we're still not trying to be contrarians around climate change just because it's hard to imagine or scary, since it's obvious and affecting things around us every year.

That is correct, for any given area you’d expect one 100 year storm for that area roughly every hundred years. When you start seeing them in that area every 10 years or so, interspersed with occasional 1,000 year storms every few decades, that’s an indicator something is going badly wrong.

Your point is underrated. There are alot of sampling bias going around.

Absolutely. But not the individual storm. Just the frequency of those storms
