Earth Systems Science

Incoming Bobcat Benji Thier already knows what he wants to do with his college degree: Save the planet.

“I am planning to study Environmental Systems Science because I did some environmental work in high school and I think it is a very important and relevant field,” he said. “I believe we need more people in this field because we need to save our planet.”

Thier, a Tiburon native and graduate of Redwood High School, visited the campus on Bobcat Day and was impressed with how much environmentally related research is being conducted.

Megalodon was the biggest shark in the world — 50 feet long or more — and one of the largest fish ever to exist. It roamed most of the world’s oceans from 23 million to 3.6 million years ago.

A new study by paleoecology Professor Sora Kim and colleagues shows the shark’s body temperature was considerably higher than previously thought and provides clues to the species’ demise.

UC Merced continues to be recognized nationally, with some programs leaping forward, according to U.S. News & World Report’s 2023-2024 edition of Best Graduate Schools released on April 25.

At UC Merced, mercury is a regional challenge that student and faculty researchers have been tackling for several years. Mercury was used to extract gold during the Gold Rush in California, and the element was also mined at the New Almaden site, at one time the second-largest mercury mine in the world near today’s Silicon Valley.

Professor Rebecca Ryals has made campus history by being named UC Merced’s inaugural Presidential Chair in Climate Change. The appointment was recommended by her peers and Dean Betsy Dumont from the School of Natural Sciences in recognition of Ryals’ outstanding research, teaching and service.

Soil biogeochemistry Professor Asmeret Asefaw Berhe — who is on leave from UC Merced while she serves as federal director of the Office of Science for the Department of Energy — has been elected a member of the National Academy of Engineering (NAE).

Graduate Division’s Competitive Edge Summer Bridge program for incoming Ph.D. students was identified as a Program to Watch by Excelencia in Education, a national effort to identify evidence-based programs that improve Latino student success in higher education.

Although climate change is still a very real challenge, the past decades of efforts to reduce the effects of human activities on the atmosphere have been potent enough to have thrown off the models scientists use to understand and forecast the atmosphere’s chemical composition and cleansing capacity.

Life and Environmental Sciences Professor Emily Moran and collaborators at several other universities are set to conduct a continental-scale analysis of climate change effects on tree reproduction.

Adding even a small amount of biochar — a charcoal-like material produced by burning organic matter — to a dairy’s manure-composting process reduces methane emissions by 84%, a recent study by UC Merced researchers shows.

The dairy industry is one of the main sources of methane in California, making up 50% of the state’s methane emissions. Reducing these emissions is a critical part of state and federal efforts to address climate change.
