NOAA says that nearly a foot of rain in one day in Louisiana confirms their models showing man-made climate change has increased the odds of floods.
On April 15, 1927, New Orleans got 15 inches of rain in 18 hours during the largest flood in US history.
New Orleans was founded in 1717, against the objections of the chief engineer who said it flooded all the time.
There has been no increase in heavy rain.
The NOAA study has no scientific basis and ignores all available actual data. Software models can be written to produce any result the author wants to produce. They are not evidence of anything other than deep corruption at NOAA.
