Megadroughts How frequent they are and what Causes Them
Abstract
Maria Kuman
Toby Ault and Scott St. George published recently the article: “Unraveling the Mysteries of Megadroughts” in the journal Physics Today of August 2018 [1]. They claim US and Mexico experienced their worst droughts (in the last 150 years) between the years 2000 and 2014. They did a lot of measurements of tree rings in the American West, which provide the most complete record of droughts. The results of their measurements are interesting, but they don’t deliver the promise in their title - they don’t unravel the mysteries of megadroughts. We do unravel the mysteries of megadroughts based on study of the glaciers.
