"Climate change and atmospheric dynamics unveil future weather extremes" | Penn press release for our (Xueke Li et al) new PNASNews study on the role of jet stream resonance in the 2021 Pacific Northwest "Heat Dome" event: penntoday.upenn.edu/news/climate-c…

"Path-dependence of the Plio–Pleistocene glacial/interglacial cycles" | Our new PNASNews article on the surprising role of hysteresis in the climate trajectory of the past few million years, including mid-Pleistocene onset of the ~100 kyr sawtooch cycle pnas.org/doi/10.1073/pn…

"Heatwaves Behind the Scenes: Drivers, Mechanisms, Changes, and Impacts" | Consider submitting an abstract to our session (A091) at AGU (American Geophysical Union) 2024 Fall Meeting in DC (co-conveners @Xueke_Li @MichaelFWehner & yours truly): agu.confex.com/agu/agu24/prel… #AGU24 #ClimateChange #HeatWaves

Happy Friday! Not sure where to start your Monday at #AGU2024? Check out these MRG and PennCSSM events! Starting with our 8:30am session Heat Waves Behind the Scenes: Drivers, Mechanisms, Changes and Impacts chaired by Prof Michael E. Mann, Xueke Li and @MichaelFWehner

"Atmospheric Warming and Planetary Wave Amplification" | My blog post on our new article (@Xueke_Li, Michael Wehner, Shannon Christiansen & yours truly) out this week in @PNASnews: michaelmann.net/atmospheric-wa… :

Climate change can amplify planetary waves, large-scale atmospheric circulation disturbances that can cause extreme summer temperature events. Planetary wave resonance events have tripled since 1950. In PNAS: ow.ly/siMz50We2sj

"Extreme summer weather patterns have tripled since the 1950s" | Great piece in Penn' s #PennToday on our recent @pnasnews article, providing critical context for the extreme heat we're seeing right now in North America and Europe: penntoday.upenn.edu/news/extreme-s…

"Temperatures reach dangerous highs as ‘heat domes’ hit US and Europe" by Attracta Mooney & Steven Bernard for the Financial Times: ft.com/content/51893d…

"Heat Domes Are Hotter and Lingering Longer—Because of the Arctic" by Chelsea Harvey for E&E News/Scientific American: scientificamerican.com/article/heat-d…

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 Xueke Li]

Since Republicans on this hellsite are getting on their high horse today and politicizing the horrific and inexcusable murder of Charlie Kirk, when we don’t have a suspect or motive yet, it’s worth reminding them of this *Trump-endorsed* GOP gubernatorial candidate last year:
