Warming makes US West megadrought worst in the modern age
A comparison of weather records since 2000 with similar time frames in past centuries has led researchers to conclude that we’re in the midst of a megadrought of historic proportions.
The assessment draws upon tree-ring data from nine Western states, stretching from Oregon and Idaho down through California and New Mexico, plus part of northern Mexico. The patterns in the tree rings served to track annual soil moisture going back to the ninth century.
