We welcome abstracts that explore geological and paleo-storm reconstructions, historical and instrumental observations, modeling studies, and climate projections to improve understanding of ETC impacts, variability, and implications for coastal risk management and resilience in a changing climate.

@mannresearch.bsky.social

There are knowledge gaps regarding these storms (limitations with paleo- and historical records, inconsistent methodologies, high computational costs). This session aims to bring together interdisciplinary research that addresses these challenges by examining ETC hazards spanning multiple timescales

UPenn researchers, including @michaelemann.bsky.social, found that Philly is likely to experience more damaging floods like Hurricane Ida. Climate change, as well as paved surfaces and overburdened city drainage systems, make Philly especially vulnerable. whyy.org/articles/phi...

Cuts to federal science funding means we’ll be more vulnerable to hurricanes and nor’easters here in the Mid-Atlantic.

When we cut critical Federal funds for science, we all pay the price. The impacts of this loss of scientific innovation will be felt especially acutely in our coastal communities. Check out my latest op-ed, published today in The Philadelphia Inquirer, to learn more! share.inquirer.com/iC6tHv

"The simulations showed that 2024’s record-setting heat was far from an anomaly. When accounting for human-caused warming, the researchers estimated it had roughly a 12 percent probability of occurring—in other words, it could be expected to occur on average once in eight years."

Mann Research Group
@mannresearch.bsky.social

"Strip out the baseline of human-caused warming from the models entirely, and the picture changes; in all 40,000 simulations without this signal, temperatures as high as those seen in 2024 didn’t even appear once."

🧵3/4 "we demonstrate that the recent global surface temperature spike is entirely consistent with expectations from the combined effects of model-predicted long-term warming and routine natural climate variability."

@mannresearch.bsky.social

🧵2/4 "A number of recent articles and commentaries have argued that the record global temperatures of 2023–2024 cannot be explained by standard climate model simulations and infer that we are witnessing an unexpected surge in planetary warming."
