Study Explores Climate-Friendly Actions to Reduce Wildfire Risks
To prevent destructive wildfires, the U.S. Forest Service thins forests and places the cuttings, called residue, into piles for burning. However, a recent study led by Jake Barker ’24 MF and a team of researchers projected that a significant amount of carbon dioxide is released during these events, which works against climate-change mitigation goals. The burns are also financially costly.
The residue burns by the Forest Service are being used to prevent catastrophic fires that have been fueled by logging, drought, climate-change, and previous government-mandated fire suppression that have led to the accumulation of debris and dense stands of small trees, which provide fuel for enormous blazes.
The study, published in Frontiers for Global Change, simulated residue burning across western U.S. forests, and estimated that the burns contributed over 1.7 million metric tons of carbon emissions annually. The researchers found that that costs for labor and equipment were also notably higher than had been reported.
The authors suggest that alternatives to burning residues, such as using them for biofuels or burying them to sequester carbon, could help reduce fire risk and carbon emissions. Steep forest terrain makes removing residues for other uses difficult and costly. They recommend the Forest Service seek subsidies to aid in funding infrastructure for climate-friendly alternatives.
“Forests play a big part in natural climate solutions,” Barker said. “We’re demonstrating the opportunity for novel and creative pathways to transform residues into a natural climate solution.”

Heavy Rainfall Linked to Drought in Northeastern U.S.
A recent study led by YSE doctoral student Samuel Jurado uncovered a surprising connection between increased heavy precipitation events and dry soil conditions in the Northeastern United States, revealing that feedback loops, not previously observed in the Northeast, contribute to regional dryness during the summer months.
The study, published in Water Resources Research and co-authored by Jackie Matthes, a researcher at Harvard University, explores how more frequent heavy rainfall and increased soil dryness can exist simultaneously and intensify summer drought through a process known as land-atmosphere coupling.
“Imagine you have a flowerpot and one cup of water,” explained Jurado. “Each day for a week, you add a bit of water to keep the soil moist and the flower healthy. Now, imagine you have two cups of water, poured all at once at the beginning of the week, and the pot is left alone. Most of the water overflows or drains out. At the end of the week, the flower that received only one cup of water remains healthy, while the other, despite receiving two cups, may be stressed and dried out. As the climate changes, the Northeast is increasingly resembling the latter flower.”
The study has implications for land management practices, suggesting a need for strategies that enhance soil water retention.
“As water management becomes increasingly challenging for Northeastern U.S. communities, it is crucial to explore how landscapes influence atmospheric conditions, especially as precipitation patterns change and more frequent summer dry periods grow beyond historical experience,” Jurado said.
YSE Students Win Questrom School of Business Sustainability Competition
A five-member team of students from the Yale School of the Environment and Yale School of Management won first place at the Boston Questrom School of Business Sustainability Case Competition for developing ideas to boost a solar company’s B Corp score.
“We worked hard over the course of two months to come up with solutions to real problems for real companies,” said team member Shivansh Chaturvedi ’26 MF/MBA.
The group earned the $50,000 prize during the third annual competition, besting more than 90 other teams in the country’s largest sustainability-focused case competition.
In the finals, the team focused on how New England-based ReVision Energy could boost its B Corp score, which measures firms’ social and environmental impact. The team calculated that ReVision could attract more female electricians by offering in-house childcare, which would save money by reducing employee turnover. The team also proposed carbon removal investments to neutralize ReVision’s environmental impact.
Chaturvedi said YSE’s interdisciplinary education helped the team clinch the win.
“We felt very confident going into that competition, knowing that we had a holistic understanding of the problem from various lenses,” he said.
Team members included Gabriel Gadsden ’26 PhD, Henry Ritter ’25 MEM/MBA, and Yale School of Management students Arjun Kumar ’25 MBA and Leigh Ramsey ’25 MBA.
Two local charities benefited, too. The competition required that the winners donate 10% of the prize to charity. The Yale team picked Save the Sound and Common Ground.
