	Communicating Policy: Raising IRA Awareness in Philadelphia (July 15, 2024) By Eryn Campbell, Lauren Lutzke, Heather Kostick, and Michael Mann for Kleinman Center for Energy Policy
	Path-dependence of the Plio–Pleistocene glacial/interglacial cycles In a new study led by Mann Research Group postdoctoral researcher, Judit Carrillo, hysteresis was identified in a model of intermediate complexity (CLIMBER-2) over the past few million years, most notably across the Mid-Pleistocene Transition (MPT).
	Compound Drought and Heatwave Events Dr. Michael E. Mann and collaborators lead by Kumar P. Tripathy investigated the risk of compound drought and heatwave events (CDHW) under “worse-case” climate change scenarios.
	The 2023 North Atlantic Hurricane Season Prediction Dr. Michael E. Mann and Shannon Christiansen at the University of Pennsylvania and Penn State ESSC alumnus Dr.
	Another Year of Record Heat for the Oceans Lijing Cheng, and numerous collaborators including Dr. Michael E Mann, have once again extended previous research to conclude that the world’s oceans were a record warm in 2022, despite the presence of La Niña conditions, for another consecutive year.

	Public Disapproval of Disruptive Climate Change Protests By Shawn Patterson Jr. and Michael E. Mann
	Past and future ocean warming By Lijing Chen, Karina von Schuckmann, John P. Abraham, Kevin E. Trenberth, Michael E. Mann et al. for Nature Reviews Earth & Environment
	Climate change threatens terrestrial water storage over the Tibetan Plateau Xueying Li and collaborators, including Dr. Mann, quantifed terrestrial water storage (TWS) for the Tibetan Plateau and project that there will be declines under mid-range carbon emissions scenario by the mid-twenty-first century.
	2022 North Atlantic Hurricane Season prediction released ESSC scientists Michael E. Mann and Daniel J. Brouillette and ESSC alumnus Michael Kozar have released their seasonal prediction for the 2022 North Atlantic hurricane season. The prediction is for another above-normal season.
	Study shows that ITCZ responses to external forcing are region-specific Byron Steinman, and collaborators including Dr. Mann, analyzed paleoclimate records of precipitation change in the neotropics and climate model simulations that span the preindustrial last millennium to assess ITCZ behavior on multicentury timescales.
