Warmer temperatures cause more water to evaporate, making both droughts and heavy precipitation more extreme. Climate change makes droughts “more frequent, longer, and more severe,” according ...
Even while natural variations in rainfall still bring on droughts, there is greater heat to draw moisture from plants, soil, and bodies of water. "For generations, drought has been associated with ...
