Science Update: Stratospheric ozone depletion a key driver of precipitation trends

A recent paper in Climate Dynamics by Paula L.M. Gonzalez and co-authors focuses on understanding the regional precipitation trends in South Eastern South America (SESA). Using 6 different climate models they show that the impact of ozone depletion on SESA precipitation has been as large as, or possibly even larger than, the impact of increasing greenhouse gas concentrations over the period 1960-1999.
