Communicating Policy: Raising IRA Awareness in Philadelphia
Philadelphians stand to benefit from the Inflation Reduction Act (IRA), but many may be unaware of how it can help them affordably make their homes more energy efficient.
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). We demonstrate that in using path-dependent forcings there is a striking divergence in the history of Pleistocene glacial/interglacial cycles.
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. In this new study, they found the effects of climate change increases the intensity, duration and frequency of CDHW events, and comment on the threat extreme heat has on socioeconomic factors.
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. Michael Kozar have released their seasonal prediction for the 2023 North Atlantic hurricane season. The prediction is for another above-normal season.
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
In mid-October, a pair of climate activists from the group “Just Stop Oil” garnered substantial international media attention.
Past and Future Ocean Warming

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. Results indicate projected excess water loss for the Amu Darya and Indus basins which present a critical water resource threat and highlights these areas as being at risk from climate change.
