Phoenix in the Climate Crosshairs

We’re not the first people on the planet ever to experience climate stress.  In the overheating, increasingly parched American Southwest, which has been experiencing rising temperatures, spreading drought conditions, and record wildfires, there is an ancient history of staggering mega-droughts, events far worse than the infamous “dust bowl” of the 1930s, the seven-year drought that devastated America’s prairie lands.  That may have been “the worst prolonged environmental disaster recorded for the country,” but historically speaking it was a “mere dry spell” compared to some past mega-droughts that lasted &ddquo;centuries to millennia.”
