Assistant Professor Daniel Ibarra is co-author of this study, which provides a new framework for examining how organisms have fundamentally altered ecosystems on a global scale across hundreds, thousands, or millions of years.
Assistant Professor Mara Freilich is co-editor on a new book, "Climate Changed: Models and the Built World," available now through Colombia University Press. The book examines models and their imperfect yet central role in understanding the relationship between global climate dynamics and the human-built environment. It compares and synthesizes the methods and function of models in disciplines ranging from architecture and planning to climate science and natural hazards research.
DEEPS PhD student Alejandra López contributes to two new briefs revealing widespread nutrient pollution, dangerously low oxygen levels in the lake, and frequent episodes of hydrogen sulfide emissions that exceed California’s health standards—conditions occurring among residents in areas that rank among the most burdened by pollution in the state. López noted, “Families live with chronic exposure to pollutants that would never be tolerated elsewhere. We call for enforceable standards and local-focused solutions that put residents at the center of restoration.”
More than 85 climate scientists declared the Department of Energy’s new climate report unfit for policymaking in a comprehensive review. DEEPS Professor and IBES Director Kim Cobb, who co-authored two sections of the review, said, “It’s really important that we stand up for the integrity of [climate science] when it matters the most. And this may very well be when it mattered the most.”
From freshly formed simple craters on the Moon to hydrogen sulfide production in the Salton Sea, DEEPS undergraduate students participated in cutting edge research throughout the 2025 summer break. We are proud to showcase some of these research projects with this photo series.
DEEPS Assistant Professor Harriet Lau recently presented at TEDx New England on the our planet's natural cycles and rhythms – from micrometers to thousands of miles, and from milliseconds to millions of years. Throughout Earth's multi-billion-year history, these rhythms collide, interact, and unfold, influencing humanity and shaping our experience of time.
ecoRI News spoke with experts about the risks that Rhode Island will face going forward as heat waves hit more frequently and for longer periods. DEEPS Chair Meredith Hastings commented, noting that when it’s hot outside, air quality tends to get worse. “Under hotter conditions we speed up reactions,” she said. “That can lead to the faster production of secondary pollution.”
Dozens of veteran climate scientists have launched a coordinated response to a Trump administration report that casts doubt on the severity of climate change. Kim Cobb, DEEPS Professor and Director of IBES, told CNN it’s significant that the Trump administration is deep-sixing the climate assessments at the same time it’s releasing a misleading new report. She also said she hopes to help “set the record straight” on climate science in their response to the DOE report.
A new art installation on Public Street by artist Eli Nixon features colorful windsocks that are raised as local air quality fluctuates. DEEPS Chair Meredith Hastings attended the windsock event and spoke about air quality issues, which she has studied as a part of her project Breathe Providence.
Through an eight-week summer accelerator focused on personal and commercial development, the Nelson Center for Entrepreneurship’s Breakthrough Lab is supporting 13 student-led ventures.
This article in Nature investigates how researchers are filing appeals, seeking court remedies, turning to philanthropy and starting GoFundMe campaigns to support their research. The article includes the cancellation of Assistant Professor Mara Freilich's NASA grant, which engaged citizens in studying the air quality around California's Salton Sea.
The study challenges the idea that the climate of northern Africa dried out around 3 million years ago, a time when the earliest known hominids appear in the fossil record.
DEEPS Shorts is a video series highlighting the diverse research within Brown’s Department of Earth, Environmental and Planetary Sciences. This week we hear from John Nicklas, PhD Candidate and Climate and Health Scientist. Created by PhD Candidate Élise Beaudin, with support from Communications Specialist Mae Jackson.
Researchers showed that hydrogen sulfide, which is associated with numerous health conditions, is emitted from California’s largest lake at levels far higher and more frequently than previously reported.
Assistant Professor Mara Freilich is one of the seventeen researchers on cross-disciplinary teams to win funding in the first year of "Scialog: Neurobiology and Changing Ecosystems", a three-year initiative that aims to spark new science exploring neurobiological response to rapid and extensive human-caused environmental changes. Freilich and her team will be exploring "From Feeding to Flux: Unraveling the Impact of Animal Behavior on Global Ocean Carbon Flow."
DEEPS Shorts is a video series highlighting the diverse research within Brown’s Department of Earth, Environmental and Planetary Sciences. This week we hear from Aikaterina “Katia” Tavri, Postdoctoral Research Associate and Remote Sensing Specialist using satellite imageries to study sea ice variability. Created by PhD Candidate Élise Beaudin, with support from Communications Specialist Mae Jackson.
DEEPS Shorts is a video series highlighting the diverse research within Brown’s Department of Earth, Environmental and Planetary Sciences. This week features Pierre Chabert, Postdoctoral Research Associate and Physical Oceanographer studying extreme flooding events in New England. Created by PhD Candidate Élise Beaudin, with support from Communications Specialist Mae Jackson.
DEEPS Shorts is a video series highlighting the diverse research within Brown’s Department of Earth, Environmental and Planetary Sciences. Our first scientist is Lily Dove, Postdoctoral Fellow and Physical Oceanographer exploring the Southern Ocean: The Lung of the Ocean. Created by PhD Candidate Élise Beaudin, with support from Communications Specialist Mae Jackson.
Experts react to the US Environmental Protection Agency's announcement that it would undertake massive deregulatory actions, including DEEPS Chair Meredith Hastings and IBES Director Kim Cobb. In an interview with The Herald, Professor Meredith Hastings explained that the EPA’s regulatory system may not be perfect, but federal oversight has been historically crucial in improving air and water quality at state and local levels.
