During the late 70s, many towns along the Mosel River were flooded, due to a "100 year flood." Some 40 years later, they're enduring another "100 year flood." What gives?

100 years ain't what it used to be ... inflation has reduced the value of 100 years to just 40 ...

LOL, and if you’ll recall, the big fear in the 70s was that of Global Cooling.
