Post by Paul AubrinGlobal warming caused droughts followed by floods as soon as 1517 (
September 27th). During two centuries t(1321-1517) there was, on the
average, a major flood in Valencia (Spain) every 20 years.

The famous 1 point comparison. :)
Yes, surprise, since the earth had an atomosphere with water vapor there
has been rain.
The main point of interest on this group is how has mankind's addition
of 50% more GHG to the atm affected things?
In the US major floods have doubled every 27 years since the 1980s.
In the Med the maximum annual rainfall event around the Med has increases
100s of mm since 1900.
We suspect that compared with the 16th cent the 21st century is
1 or 2 orders of magnitude (i.e. 10x maybe 100x) more frequent
because the atm contains 10% or more water vapor now than at least
the 1850s.
Various papers in Nature suggest worldwide flooding has doubled since 2000.
E.g. the number of countries judged to be flood prone doubled in that time.
I noticed France seems to be having a typical problem with the events.
Kinda poetic justice French people pay $600 per head to the fossil
industry to maintain their oil and gas supply and they get a commensurate
damage bill from weather disasters associated with using that supply.
You are free to stop punching yourself in the face anytime but I
assume it's a habit by now.

Flood exposure and poverty in 188 countries
Nature Communications, 28 June 2022
Global and regional flood exposure Our estimates show that globally,
1.81 billion people (23% of the world population) live in locations that are
exposed to a significant level of flood risk, facing inundation depths
greater than 0.15 meters in the event of a 1-in-100-year flood, or at least
medium risk (Fig. 1).
