CA Clean Air Law Making Strides in Overburdened Neighborhoods

Katherine E Kerlin — June 12, 2025 - 10:56am

For years, families in the Bay Area city of Richmond have lived with smoke and chemicals drifting from a nearby oil refinery. That kind of exposure poses serious health risks, but a new report from �鶹app�� shows how California’s Assembly Bill (AB) 617 is helping residents take a more active role in monitoring and reducing air pollution in their neighborhoods.

Spring-fed Rivers, Cold Waters and Trout

Andy Fell — June 09, 2025 - 1:55pm

In an age of climate whiplash, cold streams and creeks fed by aquifers in volcanic rock could be a refuge for the survival of native species, especially salmon and trout which breed in cold mountain streams.

One source of cold stream water is of course snowmelt, but that can vary greatly from year to year. Another, more stable source comes from springs drawing on water stored in porous volcanic rocks. These volcanic aquifers can feed cold water into creeks and streams year-round, potentially supporting rainbow trout, steelhead, Coho and Chinook salmon.

Fish ‘Beauty Salons’ Offer Insight into How Microbes Move Within Reefs

Katherine E Kerlin — June 05, 2025 - 9:05am

Where do you go when you’re a fish and you need a skincare treatment? Coral reefs contain natural “beauty salons,” lively social hubs of activity where fish “clients” swim up and wait to be serviced by smaller fish cleaners. The little cleaners dart under and around their much bigger clients — even entering their mouths — cleaning their scales of bacteria and parasites like a team of car washers servicing a Buick. Sometimes cleaners even rub against their clients, providing a soothing massage.

EV Battery Recycling Key to Future Lithium Supplies

Andy Fell — May 29, 2025 - 9:02am

Lightweight, powerful lithium-ion batteries are crucial for the transition to electric vehicles, and global demand for lithium is set to grow rapidly over the next 25 years. A new analysis from the University of California, Davis, published May 29 in Nature Sustainability, looks at how new mining operations and battery recycling could meet that demand. Recycling could play a big role in easing supply constraints, the researchers found.

Extreme Weather Cycles Change Underwater Light at Tahoe

After invasive American bullfrogs croak, native turtles return to Yosemite, finds a �鶹app�� study.

California Risks Billions in Economic Losses Without Water Supply Action

Katherine E Kerlin — May 14, 2025 - 2:28pm

A new economic analysis by UC professors shows the high cost of inaction on California’s perpetual water supply challenges. It estimates that the state could lose enough water each year to supply up to 9 million households — with economic losses totaling between $3.4 and $14.5 billion per year, depending on the severity of the scenario.

Helping Birds and Floating Solar Energy Coexist

How might floating solar energy projects impact wild birds and vice versa? A �鶹app�� paper outlines key considerations for a growing floating solar industry.

Sulfur Runoff Amplifies Mercury Concentrations in Florida Everglades

Sulfur from sugarcane crops is flowing into wetlands in the Florida Everglades, creating toxic methylmercury, which accumulates in fish, a �鶹app�� study finds.

Arctic Plants React Unexpectedly to Climate Change

Katherine E Kerlin — April 30, 2025 - 8:00am

Rapid climate change is upending established plant diversity and growth patterns in the Arctic, with species blooming in some areas and declining in others, suggests a study published today in the journal Nature.

The decades-long study of more than 2,000 plant communities across 45 areas in the Arctic tundra found that many locations saw vegetation change in type, abundance and growth, between 1981 and 2022.
