Sugar pines are the tallest pine species in the world, and they only grow along the West Coast of North America. They are a valued source of timber with cones as large as an adult’s forearm. But they face several problems that a new paper argues should be quickly addressed.

The sugar pine population has been declining because of changing fire patterns, drought, bark beetle mortality, a disease called white pine blister rust – and now the impacts of climate change.

A major study publishing Friday in Science reveals that carbon dioxide emissions from forest fires have surged by 60% globally since 2001, and almost tripled in some of the most climate-sensitive northern boreal forests.

A group of researchers at UC Merced has found that climate change means it takes about three months longer for California to recover from drought, and probably longer.

“Climate change has fundamentally changed the odds of getting out of drought. It has weighted the dice,” said Emily Williams, a postdoctoral scholar with the Sierra Nevada Research Institute. “This is happening because of warming in summer months, and a good portion of it is because of human-caused climate change.”

Scientists, policymakers and concerned community members will gather at UC Merced this week to compare notes and chart new directions to improve air quality and public health in the San Joaquin Valley.

A group of UC Merced researchers modeled predation behaviors, as well as changes in those behaviors, among large carnivores, developing a new theory that will help biologists assess the health of various ecosystems.

California's agriculture faces challenges from a highly variable climate with temperatures that will increase over the next several decades. Droughts are worsening and the Sierra snowpack, integral to the water supply, is volatile.

However, there are a number of ways to mitigate those changes, as outlined in a new paper coauthored by a group of UC faculty.

Construction has begun on a pilot project to install solar panels above two sections of Central Valley canals. This innovative initiative, which studies significant power and water issues, has already garnered recognition.

Project Nexus, a partnership between the Turlock Irrigation District (TID), the California Department of Water Resources (DWR), Bay Area development firm Solar AquaGrid, and UC Merced, received the Edmund G. "Pat" Brown Award from the California Council for Environmental and Economic Balance (CCEEB).

As the climate continues to change, the risks to farming are only going to increase.

That's the key takeaway from a recent paper published by a team that included UC Merced researchers. The paper dives into what those challenges are, how farmers are working to address them and what should come next.

Almost 3 billion people worldwide are projected to suffer from severe water scarcity by 2025. Thousands have already been affected in California alone, where more than 1,200 wells ran dry in 2022.

It's never been more important to find ways to make the best use of this precious resource.
