That’s about the Western US, some of which are flyover states, but most flyover states exist east of the 100th meridian and are generally more at risk to flooding than desertification!
They absolutely are, anybody relying on the Colorado River and its compact are at risk, ie the southwestern US and Denver but particularly the southern division states like California and Arizona.
Was slightly worried to hear people thinking Ohio is at any risk of desertification is all :)
