Climate scientist Daniel Swain joins UC ANR
“We are very excited to have Daniel Swain join UC ANR,” said Glenda Humiston, UC vice president for agriculture and natural resources. “He brings a unique blend of skills and expertise that are crucial to meet the challenge of climate change, here in California and across the globe. Daniel's research – and his ability to clearly explain the latest findings in climate science – can equip fellow academics, policymakers and communities with the vital tools they need to forge effective and sustainable solutions.”
Swain is known for his exceptional science communication skills, explaining weather and climate in terms easily understood by the public.
“I spend a great deal of time engaging directly with the public in California and beyond on weather, climate and disaster-related topics, so I'm thrilled to be joining UC ANR—where broad dissemination of research-based information is a key part of the mission,” Swain said. “I'm grateful for ANR's support for my unusual hybrid climate research and science communication role, and look forward to helping expand ANR's virtual and statewide reach in the years to come.”
In November, Swain was named one of Vox's Future Perfect 50 – “the thinkers, activists and scholars working on solutions to today's (and tomorrow's) biggest problems.” Vox wrote: “Our communities and institutions are largely unequipped to fully understand, let alone deal with, the impacts of climate change. That's where climate experts should, theoretically, come in. But knowing the science is one thing – being able to effectively communicate it is a whole other ballpark. Climate scientist Daniel Swain is that desperately needed liaison.”
On his widely read Weather West blog, Swain has been sharing his perspectives on California weather and climate since 2006. He hosts regular “virtual office hours” for the public on YouTube. On X/Twitter, he has more than 101,000 followers.
The “Weather Whisperer” fields hundreds of calls from reporters every year and has been the single most-quoted expert in recent years at UCLA, where he was a climate scientist in the Institute of the Environment and Sustainability. Last year, when Swain was seeking institutional support that would allow him to do science communication as well as research, a Los Angeles Times columnist wrote, “I certainly rely on Swain and other scientists to tell environmental stories.”
The term "Ridiculously Resilient Ridge" was coined in 2013 by Swain on his Weather West blog to describe the large, formidable high-pressure mass that persisted over the West Coast during winter and diverted storms away from California, contributing to the state's 2013-2017 drought.
Before joining UC ANR, Swain, who grew up in the Bay Area, was at UCLA and held a concurrent appointment as a research fellow in the Capacity Center for Climate and Weather Extremes at the NSF National Center for Atmospheric Research since 2018. While holding a 100% appointment with UC ANR, he will maintain his associations with UCLA and NSF NCAR.
Swain holds a Ph.D. in Earth system science from Stanford University and a bachelor's degree in atmospheric science from UC Davis.
He will be the keynote speaker at the California Irrigation Institute's annual conference on Jan. 27 in Sacramento. His talk is titled “Drier and Wetter in 21st Century California? Managing Increasing Hydroclimate Whiplash in a Warming World.”

Landscaping with wildfire exposure in mind can protect homes
What can Californians do to improve the chances that their homes will survive a wildfire? Simple actions taken around the home can substantially improve the odds that a home will survive wildfire, according to UC Cooperative Extension advisors.
During wildfire, structures are threatened not only by the flaming front of the fire, but also by flaming embers that are lofted ahead of the fire front and land on fuels such as vegetation or mulch next to the house, igniting new fires. Traditional defensible space tactics are designed to mitigate threats from the flaming front of the fire but do little to address vulnerabilities to embers on or beside a structure.
“Without attention to ember-related risks, defensible space efforts only address a portion of the wildfire threat—especially during wind-driven fires in which embers are the primary source of fire spread,” said co-author Yana Valachovic, UC Cooperative Extension forest advisor in Humboldt and Del Norte counties.
An updated University of California Agriculture and Natural Resources publication describes how embers, radiant heat, and direct flame contact ignite buildings and shares low-cost actions residents can take to create effective defensible space.
“The new publication is up-to-date with the changes in California's defensible space guidance, and it addresses Zone Zero, or the missing ingredient, in defense space,” Valachovic said. “The publication also provides a thoughtful discussion of plant lists and their limitations.”
The odds of a home surviving a wildfire can be substantially improved through careful attention to three things: careful design and maintenance of landscaping; awareness and management of combustible materials on the property such as leaf litter, wood piles and lawn furniture; and incorporation of fire- and ember-resistant construction materials with appropriate installation and maintenance.
“You don't have to spend a lot to protect your home from these wildfire threats,” said Valachovic.
Zone Zero, the area within five feet of the house, is the most vulnerable area around the home, according to the UC Cooperative Extension researchers. “During wind-driven fires, embers are the primary source of fire spread,” Valachovic said.
They recommend removing combustible plants, planter boxes, mulches and wood piles within the five-foot perimeter of the house and beneath attached decks.
“While it may be a radical change, clearing the area next to the house will reduce the risk of ember-caused direct flame contact and radiant heat exposure, which are responsible for many home losses,” she said. “Because embers can accumulate at the base of an exterior wall, it is also important to create a six-inch noncombustible zone between the ground and the start of the building's siding.”
Colorful illustrations in the publication depict the three-zone defensible space strategy and show how spacing out trees on a sloped landscape can prevent fire from climbing from tree to tree to reach a house at the top of the slope.
The 12-page “Reducing the Vulnerability of Building to Wildfire: Vegetation and Landscaping Guidance” is available free for download at https://anrcatalog.ucanr.edu/pdf/8695.pdf.
“Landscaping for fire is part of an overall strategy aimed at reducing risk to the home,” said co-author Steven Swain, UC Cooperative Extension environmental horticulture advisor for Marin and Sonoma counties. “To reduce the risk of home loss, start at the house and work out from there,” he recommended.
Swain, Valachovic and Stephen Quarles, UC Cooperative Extension advisor emeritus, are currently updating a publication on retrofitting houses for wildfire resiliency.
