Toby Ault and Scott St. George published recently the article:“Unraveling the Mysteries of Megadroughts” in the journal PhysicsToday of August 2018 [1]. They claim US and Mexico experiencedtheir worst droughts (in the last 150 years) between the years 2000and 2014. They did a lot of measurements of tree rings in theAmerican West, which provide the most complete record of droughts.The results of their measurements are interesting, but they don’tdeliver the promise in their title - they don’t unravel the mysteriesof megadroughts. We do unravel the mysteries of megadroughtsbased on study of the glaciers.
