New study, co-authored by AOSC professor Ross Salawitch and alumnus Laura McBride, investigates the 17-year discrepancy in projections for ozone recovery timelines, highlighting gaps in global reporting, compliance, and opportunities for action—as well as the ongoing impact of emissions from feedstocks and legacy equipment containing ozone-depleting substances. 

A new UMD-led study found that burying wood in the right environmental conditions can stop its decomposition and help curb carbon dioxide emissions.

Assistant Professor Maria Molina participated in an Ask-Me-Anything (AMA) user-led discussion on Reddit to answer questions about using machine learning to understand climate and weather extremes.
