It is said that rainforests are the Earth’s lungs, capturing carbon dioxide from the atmosphere, building it into lush vegetation and releasing oxygen and water back into the air.

Wildfire seasons are intensifying because of climate change. That means reforestation efforts will increase, making it important for scientists and resource managers to understand how to make sure restorations will thrive in the future.

There’s a whole world of activity beneath your feet. Soil holds a large proportion of Earth's biodiversity, and is the place where organisms interact with each other and with plants, serving important functions for their ecosystems.

Change is everywhere at UC Merced this year, from hiring a new chancellor to the completion of a major campus expansion. The Sierra Nevada Research Institute (SNRI), an early hallmark of research excellence at UC Merced, is also making a change: After a 13-year tenure, Faculty Director Professor Roger Bales has stepped down and Professor Tom Harmon is taking the reins.

Every Fourth of July, the Carnegie Corporation of New York honors the legacy of its founder Andrew Carnegie, by recognizing an extraordinary group of immigrants, who are now naturalized American citizens, and who have made notable contributions to the progress of American society.

About 4.5 billion people around the globe do not have access to adequate sanitation, and what they do have — typically pit latrines and lagoons — are responsible for widespread illnesses and a portion of the greenhouse gases that are warming the planet.

UC Merced Professor Rebecca Ryals and a group of colleagues have a solution that not only increases safety, sustainability and jobs, but reduces greenhouse gas emissions and waste-borne illnesses while producing an effective fertilizer for agriculture.

UC Merced Professor Peggy O’Day hopes to improve water quality in the California Delta by studying local wetlands.

O’Day is leading a new three-year study of Merced County wetlands that drain into the San Joaquin River and eventually the Delta.

Soil biogeochemistry Professor Asmeret Asefaw Berhe has been named the Ted and Jan Falasco Chair in Earth Sciences and Geology.

“The Falasco family is engaged in construction and development, so they have an intimate connection with and an understanding of the earth beneath our feet,” Berhe said. “Not only are they generous with their hard-earned resources, they are investing in a worthy cause for the Valley. They appreciate how invested we all should be in the land and the Earth.”

Soil is one of the foundations of life on Earth and could be an important part of the solution to climate change, if only we can stop treating it like dirt.

The most extreme drought event in hundreds of years caused a catastrophic die-off of the Sierra Nevada’s mature trees in 2015-2016.

A study published today in Nature Geoscience details how UC Merced Professor Roger Bales and his colleague Professor Michael Goulden from UC Irvine tracked the progress of the devastation caused by years of dry conditions combined with abnormally warm temperatures.
