El Niño is here and that means droughts, but they don’t work how you might think

“With an El Niño looming large this summer…at some point you’ll hear someone say that warmer temperatures are making drought worse. This is guaranteed to cause confusion because it’s not actually how droughts work…Most believe it’s a simple equation: rainfall goes down and the temperature rises, leading to more evaporation and an increasingly parched landscape…But the truth is much more interesting and complex, and the idea that increased evaporation is responsible for common droughts is completely wrong. In fact the issue of how droughts develop is a bit of a chicken-and-egg situation.” Most curious is explanation of drought caused by frost in PNG.
