Latest Research
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.
