We're excited to join Dr. Kate Staley, Dr. Beth Mark and @penncssm.bsky.social today for an open and supportive conversation to share our thoughts and feelings about climate change! @michaelemann.bsky.social | #upenn #penncssm #climatechange #climateanxiety

Thank you to everyone who came out to support the amazing student presentations in the 1.5* min lecture series! It was great to hear from MRG student Chris Larson on the loss of the Greenland ice sheet and @penncssm.bsky.social student Nat Glasgow on linguistic injustice in climate communication

Seems relevant today...

Happy Climate Week at Penn! We are kicking the week off strong with a 1.5* min lecture from MRG grad student Chris Larson today under the Climate Week Tent @ 12pm. See you all there rain or shine! @michaelemann.bsky.social | #climateweek 🌎🌧️ climateweek.provost.upenn.edu/event/15-min...

"Penn’s sixth annual Climate Week to highlight global ‘climate hotspots’ with over 50 events" by Norah Findley for the @dailypenn.bsky.social: www.thedp.com/article/2025... #PennClimateWeek

The start of #PennClimateWeek is just days away and we're excited to share all of our upcoming events! 🧵 1/4 @michaelemann.bsky.social | @upenn.edu | #climatecomms climateweek.provost.upenn.edu

Welcome to @upenn.edu Class of 2029! 🔴🔵 Want to learn more about the defining challenge of our time? Consider taking EESC 2300: Global Climate Change with @michaelemann.bsky.social. This course introduces processes impacting global climate and highlights changes in future climate projections.

Two articles in @pnas.org by the @mannresearch.bsky.social over the past month demonstrate why *the truth is bad enough*. We don't have to exaggerate the climate crisis to justify urgent and immediate climate action. apnews.com/article/extr... insideclimatenews.org/news/1407202...

"Strongest Nor’easters Getting Stronger" | Great piece on our new study by Michele Berger for @upenn.edu #OmniaMagazine: omnia.sas.upenn.edu/story/strong...

Important postscript on our recent study: We can confirm now that the recent heat domes over North America & Europe were part of a resonant "wave 7" hemispheric pattern that emerged in mid June, persisting through most recent data [analysis by @xuekeli.bsky.social]

Researchers work with the CLIMBER-2 carbon cycle model, which simulates oceanic, atmospheric, ice sheet, and biogeochemical processes, to explore the dynamics of climate transitions and shifts in carbon storage in the Plio-Pleistocene. In PNAS: www.pnas.org/doi/10.1073/...

"Atmospheric Warming & Planetary Wave Amplification" | I discuss our (@xuekeli.bsky.social et al) new article in @pnas.org demonstrating for the first time, an increase in incidence of the stuck & wavy jet stream patterns behind persistent summer weather extremes. michaelmann.net/atmospheric-...

Ours is the first study to demonstrate an historical increase (by a factor of three!) in the occurrence of atmospheric resonance, which is associated with many of the most devastating and deadly persistent summer weather extremes in recent years (e.g. Pacific Northwest Heat Dome of summer '21) 🧵
