Every time we get a big rain in the US, climate morons start claiming it was a 1,000 year event
So what are they doing wrong?
Your odds of winning the lottery are very small, but the odds of someone winning the lottery are quite high. What these geniuses are doing is conflating the odds of one individual station getting a 20 inch rain, with the odds of any station getting a 20 inch rain.
Big rains are not rare in the US. Alvin, Texas got 43 inches of rain in one day in 1979.
We heard exactly the same 1,000 year nonsense after the 20 inch rains of 2013 in Colorado, but Colorado got 24 inches of rain in six hours in 1935.
There are records of many other comparable rains in the US, but people make the same mistake generation after generation.
