What Does A Record-Breaking Wildfire Season Mean For Life in Alpine Lakes?

Katherine E Kerlin — April 21, 2026 - 10:39am

In the summer of 2020, MJ Farruggia embarked on the first field season of her PhD research. With a backpack full of scientific equipment and camping gear, she hiked high into the Emerald Lake Watershed high in the Sierra Nevada Mountains to install environmental sensors and collect water samples from six small lakes and ponds.

Would You Let Your Utility Control When You Charge Your EV?

Katherine E Kerlin — April 20, 2026 - 9:15am

Electric vehicles are one important way for America to use less fossil fuels — driving down emissions that cause climate change and reducing exposure to oil price shocks that threaten economic growth. But as more households buy electric cars, they must also charge those cars, which typically happens at night. So many EVs charging at once can put a strain on local electric grids. Some utilities are trying to lessen this burden by scheduling EV charging themselves, spreading charging out so that fewer vehicles need power all at once.

Bird Flu Outbreak Among CA Marine Mammals Remains Small But Concerning

Scientists and wildlife specialists continue to sample and monitor marine mammals in California, where the first cases of highly pathogenic avian influenza (HPAI) H5N1 in a California marine mammal were detected and announced last month in San Mateo County.

EPA Removal of Vehicle Emissions Limits Won’t Stop the Shift to EVs

Katherine E Kerlin — February 13, 2026 - 1:18pm

The U.S. government is in full retreat from its efforts to make vehicles more fuel-efficient, which it had been prioritizing, along with state governments, since the 1970s.

Tell Me Something Good … About Salmon

Katherine E Kerlin — January 29, 2026 - 1:22pm

For every bad thing happening in the world, there are good people trying to make things right. Sometimes they even win. That’s why I’m starting a new series on this blog called “Tell Me Something Good.”

I’m opening it up with Carson Jeffres, a 51�ԹϺ�� Davis Center for Watershed Sciences researcher who helped inspire the idea, simply by telling me something good. I needed to hear it. Maybe you do, too.

Julian Johnson’s Big Year of Birding

Katherine E Kerlin — January 27, 2026 - 3:48pm

Julian Johnson didn’t even consider himself a birder until a couple of years ago, but the 51�ԹϺ�� Davis undergraduate student broke the Yolo County Big Year record for birding in 2025. He recorded 275 species while spending more than 1,000 hours birdwatching in the country last year. His achievement came just months after a 51�ԹϺ�� Davis team broke the” Big Day” record for Yolo County.

Expedition to Antarctica: 51�ԹϺ�� Davis Tracks Melting Glaciers

Katherine E Kerlin — January 23, 2026 - 1:31pm

51�ԹϺ�� Davis scientists are in Antarctica to deploy Gull, an autonomous underwater vehicle known as a glider, that will help us understand how fast one of the world’s biggest and most important glaciers — Thwaites — is melting. Thwaites Glacier and neighboring Pine Island Glacier are potential glacial flow from the West Antarctic ice sheets. If this system collapses, it could raise sea levels across the world.

Finding that Ripe Cone Sweet Spot: Looking Back to Help the Future

Katherine E Kerlin — January 21, 2026 - 10:15am

California’s wildfire seasons are becoming more intense, and the state’s public bank of seeds to help replant and reforest lands after blazes is understocked by thousands of pounds.

A new research project out of University of California, Davis, aims to help solve that problem by using decades of data from historical cone collection records to model when cones in coniferous trees from wild stands will ripen.

LA Fires: Chemicals From the Smoke Lingered Inside Homes Long After the Wildfires Were Out

Katherine E Kerlin — January 06, 2026 - 12:16pm

When wildfires began racing through the Los Angeles area on Jan. 7, 2025, the scope of the disaster caught residents by surprise. Forecasters had warned about high winds and exceptionally dry conditions, but few people expected to see smoke and fires for weeks in one of America’s largest metro areas.

2025 Arctic Report Card Released

Katherine E Kerlin — December 16, 2025 - 2:00pm

Bright orange rivers, a greening tundra, the “Atlantification” of the Arctic and record-breaking temperatures on both land and sea are among the emerging concerns highlighted in the 2025 Arctic Report Card from the National Oceanic and Atmospheric Administration (NOAA.) Now in its 20th year, the peer-reviewed report includes chapters by 112 authors from 13 countries, each dedicated to monitoring changes in the Arctic.
