The cost of diesel is at an all-time high, with effects that will ripple through the economy, according to the University of Pennsylvania.

"In the United States, trucks carry more than 70% of all freight," said sociologist Steve Viscelli, who studies the economics of trucking. "So, when diesel spikes, transportation costs rise, supply chains tighten, and everyday goods—from fresh produce to consumer electronics—become more expensive."

Viscelli, of the School of Arts & Sciences, discusses the shifting trucking landscape in a story from the Penn Today archives.

In a separate Penn study, political scientist Erik Wibbels led a team that created Machine Learning for Environmental Event Detection, an AI model that could help policymakers understand how natural disasters impact violence, crop prices, and migration. He is collaborating with researchers including climate scientist Irina Marinov, whose students use the model to apply skills learned in her Climate and Big Data course.
