Europe and many other parts of the world are currently grappling with extreme drought—and that could be bad news for efforts to curb climate change, concludes a new global study of how shrubs and grasses respond to parched conditions.
A decade ago, with droughts forecast to become more frequent and severe in a warming world, three ecologists—Melinda Smith of Colorado State University; Osvaldo Sala of Arizona State University, Tempe; and Richard Phillips from the University of Indiana, Bloomington—grew frustrated with their field’s inability to come up with consistent results about how dry weather affects plant productivity, particularly in grasslands and shrublands.
Each team tallied the kinds and numbers of plants in the covered areas, as well as in similar plots left open for comparison. After a year of treatment, the researchers surveyed the plants again and harvested, dried, and weighed all of the aboveground plant material in the roofed and open plots.
