It is true. "New data show that extreme weather events have become more frequent over the past 36 years, with a significant uptick in floods and other hydrological events compared even with five years ago, according to a new publication" https://www.sciencedaily.com/releases/2018/03/180321130859.h...

Have you even looked out the window, lately?

Not all areas experience extreme weather. Where I live, there's basically no extreme weather ever.

Lucky you. That experience does not generalize.
