Satellite data from across California’s landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from University of California, Davis, published today in the journal Environmental Research Letters.

As part of a historic partnership between the University of California and the state of California, UC today announced it is awarding over $80 million in climate action grants. The grants will spur implementation of solutions that directly address state climate priorities. 

Four UC Davis projects are among the grantees. They include: 

How long can trees tolerate drought before the forest dies?

Researchers from UC Davis can now predict which forests could survive despite future drought. Their new method links precipitation to tree growth, and it can help people decide where to put their resources as climate change affects patterns of snow and rainfall that impact the health of forests.

On a sunny day in June, about 30 acres of land tucked along rolling hills just north of Capay were set on fire. Wearing a bright yellow, long sleeve shirt, long pants, leather gloves, hard hat and heavy-duty goggles, UC Davis Assistant Professor Emily Schlickman participated in her first prescribed burn, a planned and controlled fire that aims to help reduce wildfire risk.

For decades, Ruihong Zhang, a professor in the Department of Biological and Agricultural Engineering has been studying biological conversion of food waste to explore solutions that could address environmental challenges. Her recent research on biodegradable plastics using dairy byproducts may reduce the global level of plastic pollution.

Xiaoli Dong is putting biological soil crust on the climate change research map, a project for which she received UC Davis’ single Early Career Faculty Award for Creativity and Innovation for 2023.

The university gives one or two of the $40,000 awards annually, funded by an endowment set up by anonymous donors.

The Arboretum and Public Garden at UC Davis is about to get a fresh set of water quality data after students fanned out earlier this month along the Arboretum Waterway to measure salinity and fecal coliform levels.

The three-hour session began with a lecture, then moved to the Arboretum for sampling and back to a lab to analyze what students collected. The information will be shared with Arboretum management to help provide a glimpse into the health of the creek.

Wetlands, coastal areas and offshore waters near Alabama, Louisiana and Texas have more inactive oil and gas wells than producing ones, and the cost to permanently plug and abandon them could be $30 billion, University of California, Davis, researchers suggest.

On a warm February afternoon, Kirk Pumphrey walks down his rows of almond trees at Westwind Farms in Yolo County. He notices the buds on the branches have already sprouted pink. It worries him. The earlier the trees bloom, the more likely winter frost will damage the nuts. Early blooms are occurring more often as higher temperatures from climate change stimulate plant growth. 

Bernardo “Bernie” Bastien-Olvera, a recent Ph.D. graduate from the Geography Graduate Group at UC Davis, is this year’s recipient of the Kinsella Memorial Prize for his doctoral research on the effects of climate-driven impacts on global ecosystems and the influence on human well-being.
