Researchers discover global warming may affect microbe survival

Arizona State University researchers have discovered for the first time that temperature determines where key soil microbes can thrive—microbes that are critical to forming topsoil crusts in arid lands. And of concern, the scientists predict that in as little as 50 years, global warming may push some of these microbes out of their present stronghold in colder U.S. deserts, with unknown consequences to soil fertility and erosion.
