In recent years there has been more discussion of droughts in places like eastern Texas, which is not considered a desert, than in southern Arizona which clearly is a desert
Does this mean that arid environments are changing and it would be better to invest in farm land near Phoenix, Arizona, than near Austin, Texas, for long term financial security?
It probably is not a good idea to assume that southern Arizona will not be a desert in the future and that eastern Texas will become a desert. Eastern Texas is less prepared to deal with short term climate fluctuations than southern Arizona because the climate has been relatively stable for almost a century and during that time southern Arizona has been arid and has adapted to that environment. It is likely that eastern Texas will learn to adapt if the climate persists in becoming more arid there.
