Puerto Ricans Are Among the Most Worried About Climate Change
Residents of Puerto Rico are among the most worried in the world about climate change according to a new study by the Yale Program on Climate Change Communication (YPCCC).
The study, conducted in partnership with Rare and Data for Good at Meta, found that 93% of Puerto Ricans said they are “very worried” or “somewhat worried” about climate change; 84% said climate change will harm future generations “a great deal”; and 61% said climate change will harm them personally “a great deal.” Puerto Rico also had the highest number of respondents in the world who believe that climate change should be a high government priority.
"This says that the population seems highly attuned to climate change, potentially because of their exposure and experiences with extreme weather that have accumulated over the decades,” said Marija Verner, a postdoctoral associate at the Yale School of the Environment. “The second takeaway is that personal experience matters in how people approach these issues, and the third is really underscoring community resilience. Puerto Rico has built pretty strong adaptive capacity and strong support networks.”
The report, “International Public Opinion on Climate Change: 2023,” describes climate change beliefs, attitudes, policy preferences, and behaviors among Facebook users in 100 countries, territories, and geographic groups representing 187 countries and territories worldwide. It is one of a series of reports that YPCC has been conducting across the world in order to understand climate change attitudes, fears and behaviors. The survey was conducted by Meta from August 3 – September 3, 2023. Researchers at YPCCC are using the survey data to release findings related to public views on the links between climate change and extreme weather in the Global South and adoption of, and barriers to, behaviors that can reduce personal and household carbon dioxide emissions in the Global North.

UK Lawmakers Visit Yale to Explore Nature-Based Climate Solutions Up Close
The Yale Hixon Center for Urban Sustainability recently hosted a delegation of Members of the British Parliament as part of a four-day Connecticut visit organized by the British American Parliamentary Group. The six MPs met with Karen Seto, the Frederick C. Hixon Professor of Geography and Urbanization Science, to discuss climate policy, urbanization, and the role of cities in addressing climate change.
The visit included a tour of New Haven’s bioswales. Bioswales are a landscaping feature designed to slow, filter, and redirect stormwater runoff, slowly filtering it through sediment into the groundwater or allowing it to be absorbed by native plants. They help prevent flooding and reduce pollution that would otherwise flow into rivers and streams. The Urban Resources Initiative has partnered with the city to help lead the construction and management of the bioswales. Approximately 200 bioswales have been installed across downtown New Haven through this broader effort, with about 50 adjacent to Yale’s campus.
“Seeing the bioswale presented me with a simple and effective option I want to take back and suggest to my local authority. Not only would it alleviate flooding problems, but it could also be an attractive green feature that could enhance areas, " said Christine Jardine, Member of Parliament for Edinburgh West.
The visit also provided an opportunity to explore collaboration between UK policymakers, the City of New Haven, and YSE on sustainability and climate resilience initiatives.

YSE Doctoral Candidate Honored with ESA Policy Award
Jonathan Gewirtzman, a doctoral candidate in ecosystem ecology and biogeochemistry, has received the 2026 Katherine S. McCarter Graduate Student Policy Award from the Ecological Society of America. He is one of 20 students from universities across the U.S. to be honored with the award.
Recipients of the award travel to Washington, D.C. for policy, communication and career training and they meet with lawmakers on Capitol Hill.
Gewirtzman, a National Science Foundation Research Fellow, investigates greenhouse gas cycling in forests and wetlands aimed at informing strategies for mitigating natural emissions and enhancing nature-based climate solutions.
“ESA has been an important community for me throughout my graduate career — a place to connect with ecologists across subfields and to build leadership experience as an officer of the Biogeosciences Section. I'm excited for the opportunity to learn firsthand from scientists and policymakers working at that interface,” Gewirtzman said.

Scientists Map Long-Term Water Contamination Risks at Ohio Train Derailment Site
Yale scientists are leading a research project on the long-term environmental effects of the 2023 train derailment in East Palestine, Ohio that released hazardous chemicals, including vinyl chloride, into the air and water.
Michelle Bell, the Mary E. Pinchot Professor of Environmental Health, James Saiers, the Clifton R. Musser Professor of Hydrology, and Nicole Deziel, associate professor of epidemiology at the Yale School of Public Health, are simulating groundwater flow patterns to pinpoint the direction in which the contaminates are like to migrate. The information will be used to determine locations that should receive priority for drinking water quality testing.
“Water-related concerns were top of mind for many residents, and we hope that our project’s state-of-the-art hydrologic model can inform the situation in East Palestine as well as preparation and response for future issues,” said Bell.
The work is part of a collaboration with the University of Kentucky, and the University of Pittsburg, and is supported by the National Institute of Environmental Health Sciences of the National Institutes of Health.
