A recent study in Nature Communications, co-authored by Professor Baylor Fox-Kemper, reveals that turbulence from ocean fronts—driven by submesoscale shear—significantly influences the transfer of heat, gases, and nutrients in the upper ocean layer, impacting climate and ocean productivity, especially in winter, which could improve climate model accuracy.
Kim Cobb, a professor of earth, environmental and planetary sciences and Director of the Institute at Brown for Environment and Society, delivered the Family Weekend keynote about the inflection point at which the world finds itself — and the numerous ways that the current generation of students is rising to face critical climate challenges through research and action. “I am extremely optimistic, mostly because the work that we’re doing here at Brown is illustrative of the engagement of this institution, and our entire community in making solutions that are durable and equitable,” Cobb said.
In a recent study published in Nature Communications Earth & Environment, OCE High School Interns working with Professor Emanuele Di Lorenzo found that marine heatwaves in the Gulf of Alaska have intensified since 2013, disrupting ocean currents known as eddies, which support marine life. Using 30 years of satellite data and climate models, the team examined how these heatwaves affect nutrient-rich ocean currents called eddies, which support phytoplankton. The study revealed that marine heatwaves create high-pressure conditions that weaken coastal circulation, reducing the formation of eddies and threatening marine life.
According to new research published in the Proceedings of the National Academy of Sciences, conducted during three research cruises from 2017 to 2019 in the Mediterranean Sea, scientists discovered that tiny ocean organisms are transported to deeper waters by currents called intrusions, significantly impacting the ocean's ecosystem. “We found that because these organisms are so small, they can be swept up by ocean currents that then bring them deeper than where they grow,” said Assistant Professor Mara Freilich. “It’s often a one-way trip for these organisms, but by taking this trip, they play a critical role in connecting different parts of the ocean.”
This week, the eleventh session of the World Meteorological Organization (WMO) Research Board considered critical developments in Artificial Intelligence for weather forecasting under the leadership of Board Chair Professor Amanda Lynch.

“There’s no scenario in which melting ice in the Arctic is good news,” said DEEPS Professor Amanda Lynch, the lead author on a 2022 study in the Proceedings of the National Academy of Sciences. “But the unfortunate reality is that the ice is already retreating, these routes are opening up, and we need to start thinking critically about the legal, environmental, and geopolitical implications.”
The Community Noise Lab and Swearer Center at Brown University organized a forum titled, "Firing Back" held on November 13 at the School of Public Health. At the event, Juliet Fang, a second-year undergraduate student at Brown studying Public Health and Geology-Biology, shared data indicating that the noise levels from the firing range were higher than what the city of Cranston legally allows. Her study underscored the link between noise pollution and various health issues, including disrupted sleep, heightened stress, and cognitive impairments, as well as chronic conditions like hypertension and heart disease.
DEEPS Professor and IBES Director Kim Cobb offered commentary to TIME on the Fifth National Climate Assessment, noting, "at the center of the report are people ... who have escalating risks associated with climate change as well as clear opportunities for win-win climate action."
The last 12 months were the hottest Earth has ever recorded, according to a new report by Climate Central, a nonprofit science research group. IBES Director and DEEPS Professor Kim Cobb commented that the heat of the last year, intense as it was, is tempered because the oceans have been absorbing the majority of the excess heat related to climate change, but they are reaching their limit. “Oceans are really the thermostat of our planet ... they are tied to our economy, food sources, and coastal infrastructure.”
The Rhode Island Department of Environmental Justice has released a new environmental justice policy to prioritize racial and socioeconomic fairness in its agency practices. Professor Meredith Hastings commented, saying she listened to input from community members when deciding where exactly to put the air monitors for her research. “More needs to be done to better understand what residents are exposed to, what sources/industries are responsible and our regulatory system needs to move beyond simply expecting industry to comply by making it harder for these businesses to cause harm in the first place,” Hastings wrote to The Public's Radio.
Researchers used temperature and humidity data along with climate models to analyze humanity’s exposure to potentially lethal heat as the world warms. IBES Director and DEEPS Professor Kim Cobb said the study’s conclusions are “compelling” but not surprising. “Extreme heat is already responsible for countless deaths worldwide every year,” Cobb told CNN.
