Recently, the Nashville Zoo has made headlines for opposing the proposed data center that would be built near animal habitats. The zoo had planned to eventually buy part of the land for a future educa...

Do we really want to play dice with our planet?

Penn study declares that Hurricane Ida's Philadelphia flood was a warning that climate change could make such storms a regular occurrence.

During the aftermath of Hurricane Ida, the Schuylkill River rose to levels that hadn’t been recorded in more than 150 years.

Cuts to climate science risk halting or even erasing decades of progress in global change research—just as risks from rising seas demand better data, informed decisionmaking, and faster action.

Storm tide hazard is dominated by the cool-season storms (ETCs) in the US northeast and the warm-season storms (TCs) in the US southeast In the mid-Atlantic US, cool-season storms drive more freq...

Research from climate scientist Michael Mann, Presidential Distinguished Professor of Earth & Environmental Science, and colleagues vindicates climate models and reframes the record heat of 2024.

We employ a semiempirical approach combining climate model simulations and observational temperatures to assess the likelihood of recent global tem...

New Penn research shows that Hurricane Ida wasn’t a once-in-a-century anomaly but a preview of how climate change, urbanization, and aging infrastructure are rewriting flood risk.

High-resolution sensitivity experiments show that tropical cyclones can induce long-term oceanic temperature perturbations, which affect the mean state and variability of the Kuroshio Current through ...
