UC Climate-Change Research is One Focus of Global Summit, New Reports

California aims to lead the nation — and the globe — in climate change research, policy and action — in large part through climate-focused research conducted at University of California campuses and labs.

Some of that research, including from UC Merced, will be on display this week as climate-change scientists, policymakers and trailblazers from around the globe gather in San Francisco for the 2018 Global Climate Action Summit .

Soil Can Sequester Planet-Warming Carbon. The Merced River is Helping Scientists Understand How.

Soils are carbon sinks, storing more planet-warming carbon than the atmosphere and all animal and plant life combined.

But they can also release massive amounts of stored carbon into the atmosphere. Given carbon’s central role in climate change, understanding the forces that govern how soils absorb and release carbon is crucial.

Following a Devastating Pandemic, California’s Sea Stars are Evolving

In 2012, Environmental Systems graduate student Lauren Schiebelhut was collecting DNA from ochre sea stars living along the Northern California coast — part of an effort to study genetic diversity in various marine species that serve as indicators of habitat health. She had no idea that just one year later, most of the sea stars would be dead.

Engineering Students Get an Inside Look at Wastewater Treatment

Three field trips this semester gave Professor Marc Beutel’s students an up-close understanding of biological wastewater processes used in treatment plants across the country.

Most recently, they toured the wastewater treatment plant in Oakland, operated by East Bay Municipal Utility District. The plant treats sewage for more than 685,000 people in the East Bay using a process called “activated sludge.” Bacteria convert organic waste to carbon dioxide and bacterial biomass (aka activated sludge), and once the bacteria settle out, the result is clean, clear water.
