Research from climate scientist Michael Mann, Presidential Distinguished Professor of Earth and Environmental Science, and colleagues vindicates climate models and reframes the record heat of 2024.

The National Center for Atmospheric Research (NCAR) has played a key role developing the science of climate modeling and the measurement of climate observations going back more than a half century.

The COP30 global climate summit in Brazil may have been the last opportunity for the nations of the world to reach an agreement that limits planetary warming below catastrophic (>1.5C/3F) levels.

After a little less than a year in the position, I’ve decided to step down as Vice Provost for Climate Science, Policy, and Action (“VPC”) at Penn.

We have a new study out in the latest issue of the Proceeding of the National Academy of Sciences examining trends in the characteristics of highly impactful U.S. east coast winter storms known as nor’easters (for the unusual northeasterly–that’s, from the

Here’s the press tip from PNAS on our new article demonstrating an increase over the past 70+ years in the occurrence of quasi-resonant amplification (“QRA”) of planetary waves in the Northern Hemisphere that is tied to persistent summer weather extremes.

Now that the 2024 Atlantic hurricane season seems to be coming to a close, it is worth reflecting on what transpired and what we might learn from it.
