I don’t think they are counting the droughts in the 1950s or 1930s as “recent memory.”

Probably not. But both were worse.

Clue: The Great Plains experience a dry period every 20 years-or-so -- see 1930s, 1950s, 1990s and 2010s. In the 1970s, it was a relatively mild droughts, but we were consumed by the "New Ice Age".

There is a cyclical pattern in there somewhere...

And it generally conforms to the 22-yr sunspot cycle...

The cycle is four full solar cycles ~ or 80 to 85 years! They have the same cycle at the same time in China ~ their records go back thousands of years.

Sometimes there are variations.

It's pretty clear a cycle like that has to be related to regular energy cycles in the Sun.

The earliest serious European settlement in North America started toward the end of one such cycle ~ and never really got going until as late as 1621 when you had several near simultaneous successful attempts in Cape Cod, New York, Virginia, and Florida.

All the Great Droughts are followed by a recovery that involves rain and reintroduction of extensive grasslands ~ which bring about a population peak for rodents of all sorts ~ and with them fleas ~ and with them the arrival of hanta virus and widespread death among the humans who survived the previous 80 years of drought.

This can take a bit of time. If we date the end of the Great Drought that started in the 16th century (in North America) as being at that 1621 date, then we note the widespread death of the Indians in the fall and winter of 1648, that gives us a lag time of more than 25 years ~ or roughly a complete solar cycle (two 11 to 13 year periods marked by sunspot frequency).

The ends of two great drought cycles after 1621 land at 1701, 1782, and 1863 ~ then 1944/45 (with starvation by famine in Europe for the first time since back in the 1840s). ~ The end of a Great Drought cycle is always related to some sort of significant historic event ~ extensive settlement in America, War of Spanish Sucession, American Revolution/French Revolution, Civil War, end of WWII, and whatever happens in 2125!

Bad as last year's drought was, we may have a good 10 to 12 more years of this, with each year worse than the last.

The good news is the development of some new filtering materials that work effectively to clean salt out of water. Now, to pump that stuff uphill to the Great Plains.
