Using Models to Test the Physics of Observational Instruments in the Atlantic Ocean

A recent study bridges observations and modeling, and shows a way to make improvements to the observational instruments climate scientists rely on to study global circulation patterns. 

Study Proposes New Way to Define Drought, Capturing Natural Variations and Human Actions 18 May 2021

Study Proposes New Way to Define Drought, Capturing Natural Variations and Human Actions

While drought is commonly defined by precipitation and runoff deficits, the study challenges this understanding by proposing a new definition: anthropogenic drought. Within human‐water systems, drought must be defined and understood as the complex and interrelated dynamics of both natural and human‐induced changes, the authors say.

Greenhouse Gas and Aerosol Emissions are Lengthening and Intensifying Droughts 18 May 2021

Greenhouse Gas and Aerosol Emissions are Lengthening and Intensifying Droughts

CPO-funded study shows human-caused boost to drying in Americas, Africa, and Asia

“There has always been natural variability in drought events around the world, but our research shows the clear human influence on drying, specifically from anthropogenic aerosols, carbon dioxide, and other greenhouse gases,” said lead author Felicia Chiang from the University of California, Irvine.
