While scientific reports continue to mount confirming that global climate change is increasing temperatures, causing more frequent weather extremes and raising the sea level in California, UC Cooperative Extension is working to ensure the worst predictions are avoided and California residents and businesses will be able to adapt to the change.
Each year, a diverse group of UC Agriculture and Natural Resources academics and program implementation professionals meet to share and collect the latest climate change experiences, ideas, science and solutions. The team works with farmers across the state to improve production practices and minimize environmental impact, conduct agricultural and natural resources conservation research, and coordinate programs like California Naturalist and UC Master Gardener, which recruit and educate volunteers to reach out to communities statewide to extend research-based information.
Reaching real people
In 2019, extension practitioners explored new approaches to delivery of information and services. For example, the first speaker addressed the way climate change impacts may be viewed through the lens of African-American or First Nation experiences, influenced by poverty, historical trauma and even spirituality.
Theopia Jackson, clinical psychologist at Saybrook University in Oakland, encouraged the team to consider whether assisting Americans navigating the changing climate or suffering the consequences of extreme weather events have “the bandwidth to take in one more helping hand.” Jackson has a long history of providing therapy services, specializing in serving populations coping with chronic illness and complex trauma.
Jackson suggested helpers ask themselves, “Are we inadvertently causing more stress than good? Do I have a sense for what they are already dealing with before bringing something new into the community?”
Jackson said the conversation about climate change in many communities might be more productive focused less on whether climate change exists or not, and instead on how to “join with them around the human experience.”
“If I'm trying to ‘talk them into it,' I need to step back,” Jackson said. “The conversation could be about scarcity or lifestyle. We need to find a way to join and hope they will get it before we've done irreversible damage.”
The careful selection of terminology and approach in climate change conversations was also raised by Dan Sonke, director of sustainable agriculture for Campbell's Soup. The company's primary and best-known product is soup, but it owns other familiar brands, including Pepperidge Farms, Snyder Pretzels, Kettle Chips and Emerald Nuts.
In California, Sonke works closely with farmers producing fresh produce to be used in Campbell's products, particularly processing tomatoes. During his career, he also worked in Campbell's marketing, based on its “corporate purpose.”
“We make real food for real people,” says the Campbell's corporate purpose. “People love that our food fits their real lives, fuels their bodies, and feeds their souls. And they appreciate knowing what goes into our food, and why — so they can feel good about the choices they make, for themselves and their loved ones.”
Sonke was hired to increase the use of sustainable farming practices by the company's producers and help farmers apply for grant funding from the state to implement climate-smart irrigation practices. The company was able to track a 20 percent reduction in water use and document a significant reduction in the emission of nitrous oxide, a greenhouse gas. The program is successful, but isn't driving their farmer communications or soup sales, Sonke said.
“Farmers don't think in terms of climate change, but they respond to what they know,” Sonke said. “Consumers don't respond to climate change adaptation in terms of what products they buy. They respect sustainability, but have no understanding of ‘sustainable agriculture' and ‘carbon sequestration.'”
Growing UCCE climate mitigation, adaptation and resilience programs
UC ANR is working on new ways to reach out to farmers and the public with information on climate change. Six community education specialists have been hired and four more are being recruited to work in counties around the state to help farmers access programs that will help them reduce greenhouse gas emissions on farms and dairies, build resilience to climate change and increase profit.
The Climate-Smart Farming Program is a collaborative effort with the California Department of Food and Agriculture focused on implementing on-farm solutions to improve soil health, nutrient management, irrigation management, on-farm composting and manure management.
The CDFA programs involved are:
- State Water Efficiency and Enhancement Program
- Healthy Soils Program
- Alternative Manure Management Program
The new community education specialists are already deployed in Mendocino, Glenn, Yolo, Santa Cruz, Ventura and San Diego counties. The four positions under recruitment will serve Imperial, San Joaquin, Fresno and Kern counties. To get information about these programs, contact:

To reach a broad swath of California residents with research-based information on climate change mitigation and adaptation, UC ANR's California Naturalist program is leveraging its well-established partnerships with formal and informal science education institutions across the state to create a legion of climate stewards. At the team meeting, CalNat coordinator Greg Ira announced that the California Naturalist program has hired an academic coordinator to develop curriculum that will allow existing partners to deliver the material as part of the California Naturalist program. The graduates of this California Naturalist course focused on climate change will be encouraged to engage in volunteer service that helps build community resilience to climate change. These include participation in local adaptation planning efforts, community and citizen science projects, or addressing issues of social justice. The coordinator begins Feb. 19.
Renata Brillinger of the California Climate Action Network shared optimistic thoughts about the opportunities for climate change mitigation, adaptation and resilience. In terms of politics, she said California leadership has accepted climate change as a settled matter and are supportive of programs to address the issue. At the federal level, it is not easy to talk about climate change, but “that will change,” she assured.
Brillinger said biodiversification of California is an exciting area for climate change adaptation. Research is needed to understand how to shift crop locations for future production, and determine where, for example, water-intensive crops or orchards with chill requirements should be grown. More information is needed, she said, on how healthy soil will relate to climate resilience in agriculture.
“We have to reinvest in extension and Resource Conservation Districts,” Brillinger said.
Other possible climate change outcomes in California may be returning farmland to less-intensive uses, such as grazing. Fallowing land was one way that the agriculture industry coped with the drought of 2011-16, and implementation of the Sustainable Groundwater Management Act – a direct result of the drought – is estimated to take 1 million acres of farmland out of production. This approach won't be a solution for all farmers and ranchers, said David Lile, UC Cooperative Extension natural resources advisor.
“Ranchers and farmers interested in long-term sustainability, keeping the farm in place, will need help to integrate competing forces,” Lile said. “Economics will not be the only driving force.”
In the California agriculture industry, the climate change discussion is less about whether disruption is coming than it is about how farmers will adapt, reported John Cox in the Bakersfield Californian.
Cox spoke to a Delano farmer who doesn't like debating climate change, but he has thought a lot about how to deal with it.
"As a grower, you just take it as it comes," he said.
"Everybody I know in agriculture says, 'Yes, the climate's changing and adaptation to that climate change is crucial.' So that's not controversial," said Dan Sumner, director of the Agricultural Issues Center, a UC Agriculture and Natural Resources statewide program. "At the same time, that doesn't mean they buy into every public policy proposal for mitigating the climate change."
Climate change is likely to prompt farmers to grow different varieties or different crops.
But even as California agriculture may struggle to adjust to climate change, so will its competitors overseas, Sumner said. The real question is whether the state's farming climate will remain superior in relation to that of other countries producing the same crops, he said.
In the Washington Post, Adrian Higgins reported on the impact of climate change to agriculture across the nation. From Appalachia to North Carolina to California, milder winters are inducing earlier flowering of temperate tree fruits, exposing the blooms to increasingly erratic frost, hail and other adverse weather.
Breeders are working to develop new varieties, said Katherine Jarvis-Shean, a UC Cooperative Extension orchard systems advisor in Yolo County. But new trees typically take two decades of methodical breeding to create, exposing existing varieties to the vagaries of shifting winters and springs.
“The consumer will begin to know it's happening in the coming 10 to 20 years,” Jarvis-Shean said.
A $4.6 million grant to UC Merced and UC Irvine will help UC Agriculture and Natural Resources researchers develop new tools and methods for California land owners to better manage the state's forests, shrub lands and grasslands.
California's Strategic Growth Council agreed to fund the Innovation Center for Advancing Ecosystem Climate Solutions, a three-year program co-led by UC Merced Professor Roger Bales and UC Irvine Professor Michael Goulden. The money comes through California Climate Investments, a statewide initiative that puts billions of cap-and-trade dollars to work
The goals include reducing wildfire risk, improving long-term carbon sequestration and bolstering resilience in the face of climate change, with an emphasis on California's rural regions and low-income communities.
“Our part of the project is to work with stakeholders and identify areas where we can focus management practices to promote healthy forests, minimize wildfires, improve water security and increase carbon sequestration,” said Toby O'Geen, UC Cooperative Extension soil resource specialist at UC Davis.
“Right now, many of California's forests, shrub lands and grasslands are carbon sources, and we need to change them into carbon sinks,” said Bales, director of the Sierra Nevada Research Institute and distinguished professor of engineering. “Our research will address information bottlenecks to guide decision making, build local capacity for science-based land management and develop methods for translating benefits of land restoration into financing for land restoration.”
California's recent drought, tree die-offs, wildfires and rising temperatures all point to the necessity of improved forest stewardship, Goulden said.
“Officials in the state government and agencies recognize this need, but uncertainty over how to proceed has sometimes slowed progress,” he said.
Most of the work will be conducted by scientists at Merced and Irvine, but collaborators from UC Berkeley, UC Davis, Stanford University, San Diego State University and the University of California Division of Agricultural and Natural Resources, as well as state agencies, will play important roles.
“This research will enable UC Cooperative Extension advisors to provide better advice to land managers to reduce the severity of wildfires,” said Glenda Humiston, UC vice president for agriculture and natural resources. “Severe wildfires are not only releasing greenhouse gases, but polluting the air of many communities, aggravating the health of people in less-affluent, inland areas such as Tulare, Yuba and Mariposa counties.”
At UC Merced, an interdisciplinary group of researchers from two departments — Civil & Environmental Engineering and Management of Complex Systems — will collaborate with UC Cooperative Extension and engage with local stakeholders. The group will study and identify the most-effective land-management practices, in terms of water conservation, forest health, fire resistance and carbon capture.
“We will develop the spatial data and analysis tools to plan landscape restoration, develop local capacity for better managing the state's wildlands in a warming climate, and enumerate the greenhouse gas and other benefits from investments in land management,” Bales said.
Goulden, professor of Earth systems science, said UC Irvine researchers will use a big-data approach to analyze observations collected by satellites since the 1980s to measure the efficacy of thousands of past and ongoing forest treatments, while UC Merced takes a different approach.
“We will work with groups in rural communities to systematically evaluate how well, or poorly, our products can support decision making,” Bales said, “and then develop both implementation pathways and policy recommendations to better and more-quickly implement landscape-restoration and carbon-capture projects across the state.”
Because there are critical gaps in the understanding of carbon cycles, uptake by forests and negative feedback from climate change, this project initiative has been established to develop new knowledge through measurements and modeling. Researchers will synthesize the resulting data to produce actionable information for stakeholders.
Bales and Goulden agreed the Innovation Center will target low-risk, high-yield opportunities to reduce California's greenhouse-gas contributions.
Just a small improvement in management efficiency will have meaningful benefits — on the order of several million metric tons of CO2 per year, Goulden said.
The program will also benefit low-income communities in the state by reducing wildfire risk, which disproportionately impacts poorer areas in California; by maintaining water quantity through better vegetation management; by fostering tourism in disadvantaged locales; and by preparing students in these areas for careers in sustainability and climate resilience.
Bigcone Douglas-fir is an evergreen conifer native to the mountains of Southern California. Repeated wildfires and drought are threatening the species' existence in its native range, reported Bettina Boxall in the Los Angeles Times.
The reporter visited a Santa Barbara County site peppered with tall, dead trees where UC Cooperative Extension fire specialist Max Moritz is studying the species' fate.
"You don't see anything," he said. "It has a fairly depressing quality to it, given the mortality and no regeneration."
The area was burned by the Zaca Fire 11 years ago, something the fire-resistant conifer can generally withstand. Moritz and research assistant Ryan Salladay found evidence that the trees survived the fire, but then died sometime later. They are trying to determine what did them in by recording the aspect of the slope, collecting tree core samples, measuring the water stress in living trees, looking for wildfire impacts, and checking for seedlings.
“The drought-following-fire issue is a total reshuffling of what might come back or survive,” Moritz said.
How they survived: Owners of the few homes left standing around Paradise, Calif., took critical steps to ward off wildfires
(Washington Post) Sarah Kaplan, Frances Stead Sellers, Nov. 30
…Though the United States spends upwards of $2 billion each year on fire suppression and billions more helping communities recover, the current budget for the Federal Emergency Management Agency's Pre-Disaster Mitigation Grant Program is just over $200 million — and it must address hurricanes, earthquakes and a host of other natural hazards as well as fires. Cal Fire provides grants for forest management and tree removal, but not structure modification.
The budget for the University of California Cooperative Extension program, which conducts fire research and outreach to homeowners, has been cut by almost half since 2000. There are now fewer than 20 extension advisers in forestry and fire serving a state with 40 million people and 15 million acres of public lands.
Opinion | To Help Prevent the Next Big Wildfire, Let the Forest Burn
(NY Times) Ash Ngu and Sahil Chinoy, Nov. 29
Before Euro-American settlement in the 1800s, fires burned about 1.5 million acres of forest each year, on average, according to an analysis of fire return intervals by Scott Stephens, a professor of fire science at the University of California, Berkeley. Skies were most likely smoky through much of the summer and fall, and most forests in California burned every five to 25 years from wildfires caused by lightning or Native American burning practices, he said.
Farmers make a “Romaine Recovery” after E. coli Outbreak
(NBC PalmSprings) Daytona Everett, Nov. 28
The FDA has now connected the Central Coast of California to 43 cases of E. coli across the country. However, romaine lettuce farmers in the Coachella Valley are just now bringing in their first winter harvest.
...The FDA now requires every package to “clearly and prominently label all individually packaged romaine products to identify growing region and harvest date for romaine; and to clearly and prominently label at the point of sale the growing region when it is now possible for romaine lettuce suppliers to label the package (e.g. individual unwrapped whole heads of romaine lettuce available in retail stores).”
“That also gets difficult because they harvest the lettuce and they stick a bunch of these in a box and then they go to a processing facility and you may be combining several different fields at once when you're processing that,” Milt Mcgiffen, an extension vegetable specialist from UC Riverside, said.
Wildfire, Landscapes and Debris Fields: Mapping Risks After Major Wildfire
(Capital Public Radio) Beth Duncan, Nov. 27
Geologist spend a lot of time creating landslide risk maps after a major wildfire happens. The slope of the landscape, amount of rainfall and underlying geology of an area all play a role in how likely an area might be affected.
Forestry Specialist William Stewart explains what geologists are concerned about as winter storms move through the areas hit by wildfire this year.
“After the wildfire, there's a lot of burnt logs and other things there, but what happens when it starts raining is it'll saturate the soil and you'll start to get soil movement. And once you get a fair bit of it moving down, it can pick up boulders and other things in the soil, and pull down whole trees. So a debris flow has both mud and water and big chunks of rocks and logs in there and that's what if it hits a bridge or a home, or commercial center, can just wipe it out. It's just a huge amount of force that just levels everything in its path.”
California Economic Summit Looks to Elevate Rural California
(AgNetWest) Brian German, Nov. 27
…“One of the things we really started digging into these last few years there, as part of our Working Landscapes Action Team and the summit as a whole, is this concept of there's two California's here,” said Vice President of UC Agriculture and Natural Resources, Glenda Humiston. “You've got predominately coastal, large, urban areas here that are doing pretty well. But then you've got the rest of California that's still really hurting. High poverty, high unemployment, not the economic opportunities that they ought to have.”
Humiston explained that at last year's summit they were able to launch the Elevate Rural California initiative, with a goal of addressing three specific areas over the next few years. “Water infrastructure, biomass, high-value biomass opportunities I want to qualify that strongly, and then the broadband, particularly rural broadband,” Humiston noted.
Why There Are Challenges To Doing More Prescribed Burns As Part Of Forest Management
(NPR All Things Considered) Ezra David Romero, Nov. 27
…But can the use of prescribed burns be expanded?
Roger Bales with the Sierra Nevada Research Institute at UC Merced says yes. “They can be scaled up as long as we can provide the financing to do them,” Bales said. “As long as we do them in a way that doesn't degrade the air quality.”
…The cost of a prescribed burn varies depending on time of year and resources. Robert York with UC Berkeley's Blodgett Forest Research Station says the warmer and drier the climate, the more expensive a burn.
Still, York supports burning year-round. “If the conditions are good, let's have lots of burns going on in the Sierra Nevada,” he said.

Who is Responsible for Burned Trees After a Wildfire?
(NPR Morning Edition) Eric Whitney, Nov. 26
…SCOTT STEPHENS: I would be very nervous about big oaks and potential for them to come down because the oaks, a lot of times, have heart rot. They have rotten material inside the center. And a lot of times a smoldering fire can burn in there for days and days and days. I've been around oaks like that. And all of a sudden, a week later - boom - it comes down.
WHITNEY: The danger can persist a lot longer than a week, Stephens says, as burned trees that are strong now continue to deteriorate.
STEPHENS: Probably by year four, five, they start to really get less structurally sound. Then, of course, you get a wind event, big storms, and they start coming down in earnest. And by year 10, they're coming down a great deal.
California dairy program celebrates 20 years
DairyBusiness, Nov. 26
…Recognizing a need to respond and be proactive, a committee of dairy producers, government agency representatives, industry leaders, and university specialists gathered to create the California Dairy Quality Assurance Program (CDQAP), ensuring high-quality milk production and continuous improvement in environmental stewardship. It was also a prime opportunity to demonstrate the commitment of the California dairy industry to producing high quality, safe products, in an environmentally friendly, animal-care conscience manner. Initial funding was provided by the California Farm Bureau Federation, California Department of Food and Agriculture and the California Dairy Research Foundation (CDRF). Dr. Michael Payne, a University of California veterinary researcher was brought on board to direct the program and Dr. Deanne Meyer, University of California Cooperative Extension specialist, was enlisted to develop educational programs. Continued CDRF funding provided an important direct tie to dairy producers through check off dollars, and industry expertise.
Are Your Vineyards Smart Enough to Beat the Heat?
(Growing Produce) Matthew Fidelibus, Nov. 24
…A number of strategies can be considered to adapt to increasing temperatures. Small increases in temperature might be mitigated by employing various cultural practices including pruning, irrigation and fertilization, canopy management, and crop protectants, which may help reduce fruit exposure and reduce crop load.
Irrigation and fertilization can be used to help establish sufficient canopy shade before heat waves occur. The possibility of having overexposed fruit during heat waves should be considered when evaluating canopy management practices such as leafing and shoot positioning. Crop protectants such as particle films may provide protection for overexposed fruit.

Fixing state's fire problem: Costly, complex, next to impossible
(SF Chronicle) Kurtis Alexander, Nov. 21
…Bill Stewart, a forestry specialist at UC Berkeley, said that technology has helped fire scientists pinpoint areas where wind, heat, vegetation and other factors conspire to pose the greatest threats. It's just that the risk maps aren't being used to guide development.
“We need more than an academic paper here and there on wind,” Stewart said. “The number of windy days per year should help determine new zoning policy for planners.
Actually, Even California Says Trump Is Right About the Wildfires
(RealClear Politics) Betsy McCaughey, Nov. 21
President Donald Trump's critics are belittling him for not buying the politically correct narrative that global warming is to blame for the California wildfires. Instead, Trump correctly points to decades of mistakes by state and federal forest agencies that caused the woodlands to be become overly dense and blanketed with highly flammable dead wood and underbrush.
… This multifaceted approach is too much to put in a mere tweet. But University of California forest expert Yana Valachovic concedes that Trump's "general sentiment is correct."
Living on the Edge
(Slate Magazine) James B. Meigs, Nov. 20
…But the photos tell a different story. Within Paradise itself, the main fuel feeding the fire wasn't trees, nor the underbrush Trump suggested should have been raked up. It was buildings. The forest fire became an infrastructure fire. Fire researchers Faith Kearns and Max Moritz describe what can happen when a wildfire approaches a suburban neighborhood during the high-wind conditions common during the California fall: First, a “storm of burning embers” will shower the neighborhood, setting some structures on fire. “Under the worst circumstances, wind driven home-to-home fire spread then occurs, causing risky, fast-moving ‘urban conflagrations' that can be almost impossible to stop and extremely dangerous to evacuate.” The town of Paradise didn't just experience a fast-moving wildfire, its own layout, building designs, and city management turned that fire into something even scarier.
…Of course, when fires do occur, the residents of these areas suffer the most. The question is how to provide the right incentives for people so that we limit the chances of this happening again. Looking ahead, “We need to ensure that prospective homeowners can make informed decisions about the risks they face in the WUI,” Moritz, Tague, and Anderson say.
Why California Can't Chainsaw Its Way Out Of A Raging Inferno
(BuzzFeed) Peter Aldhous, Nov. 20
…Still, supporters of thinning argue that it is a viable option in some forests, especially dry pine and mixed-conifer forests at lower elevations. Historically, forests like these burned with low intensity every decade or so, keeping them patchy and fairly sparse. There, decades of fire suppression should be countered with careful thinning to mimic the natural state, according to Scott Stephens, a forestry scientist at the University of California, Berkeley.
Stephens has compared low-elevation forests in Southern California with those over the border in Baja California, Mexico, where fire suppression didn't begin until the 1970s. The naturally patchy Mexican forests, he has found, are much more resilient: Even in the face of a four-year drought and a 2003 wildfire, only 20% of the trees died. (In the Cedar fire in San Diego County that same year, between 40% and 95% of trees in the affected areas perished.)

Santa Maria-Bonita School Districts teams up with 4H for kids career day
(KEYT) Naja Hill, Nov. 18
Santa Maria-Bonita School Districts came together for a career and leadership day at Liberty Elementary. The event, called 4H SNAC, was a collaboration between UC CalFresh Nutrition and the youth organization 4 H. SNAC stands for Student Nutrition Advisory Council.
The goal of the youth program is to advocate child development to 5th and 6th graders in underserved, low-income communities. Various guest speakers came to teach kids how to live a healthy lifestyle.
The event was 4H's 4th annual career day. One topic of focus was presentation skills. The students also got an opportunity to speak to professionals from different fields such as firefighters, a nurse, and a dentist.
Trump suggests Californians can rake their forests to prevent wildfires. (He is wrong.)
(Washington Post) Avi Selk, Nov. 18
“His general sentiment is correct — that we need to manage fuels,” said Yana Valachovic a forest adviser with the University of California's Cooperative Extension program. “And yeah, managing that pine litter adjacent to our homes and buildings is super important. … But the reality is, to manage every little bit of fuel with a rake is not practical.”
Raking is an effective way to clear light debris like leaves and pine needles away from residences, she said. It's of much less use on the forest floor, where infernos burn through swaths of brush and large debris that only heavy machinery can clear.
California's problems are complicated, she said — a combination of hot, dry climates, poor community design and “100 years of fire suppression” that helped turn forests into tinder boxes.
How Trump administration pressure to dump 4-H's LGBT policy led to Iowa leader's firing
Katherine Soule, the chair of an LGBT working group in 2016 and a leader of California's 4-H, said group leaders were asked to adapt the Obama administration's Dear Colleague letter protecting gender-identity rights for 4-H.
Soules and a group of Western 4-H leaders created a best-practices document that became the foundation of a national guidance document.
...The about-face on the LGTB policy by national 4-H headquarters left some 4-H volunteers angry and program officials confused, according to the Register's investigation.
“I feel bad for the folks at USDA,” Glenda Humiston, the vice president of the University of California's Agriculture and Natural Resources, told other 4-H leaders during a May training video. “I think they are in between a rock and a hard place.”
Lessons from Camp Fire: Staying alive in California fire country

Facts Matter: President's posts on wildfires misleading
(Chicago Daily Herald) Bob Oswald, Nov. 17
The current wildfires aren't forest fires and are not the responsibility of forest management, the Times said.
"These fires aren't even in forests," Max Moritz, a wildfire specialist at the University of California, Santa Barbara, told the Times.
The Camp and Woolsey fires began where communities are close to undeveloped areas, the Times said. Fires in these locations are more deadly and costly because of the proximity to homes and towns.
Why didn't PG&E shut down power in advance of deadly Camp Fire? Here's the data.
(Mercury News) Matthias Gafni, Nov. 17
…Thomas Scott, who has written about fire management in California's wildland urban interface and works with the UC Division of Agriculture and Natural Resources, wonders if the decision to keep power on may have had to do with the complaints the utility received after its October shutdown.
“Any rationale they had for keeping the lines hot has tragically backfired for everyone involved,” he said. “Can't understand what they were contemplating; perhaps they maintained power until the last possible moment because that action breeds unhappy customers and dangerous situations if power is turned off.”
Examining Jerry Brown's veto of California wildfire legislation and the criticism of it
(Politifact) Chris Nichols, Nov. 16
Bill Stewart, a forestry specialist at UC Berkeley, reviewed the bill and Brown's veto message. He said in an email, "I do not think it would have made much of a difference, as the amount of funds was not that great ($582,000 that may have just led to some hiring of consultants and a lot interaction with the communities) and, more importantly, no new advances would have been made."
Stewart, however, went on to describe the legislation as "a good shot across the bow to the (Brown) administration to do more. This area of risk assessment and mitigation has been woefully underfunded for decades."
How fierce fall and winter winds help fuel California fires
(The Conversation) Faith Kearns and Max Moritz, Nov. 16
… Fire hazard is determined by a variety of factors that include vegetation, topography and weather. Add people and homes, and you get fire risk. While wind is one of the biggest factors in fire spread, it also generates flying embers far ahead of the fire itself.
… Managing the type and amount of vegetation, or “fuel,” in an area provides a set of tools for altering fire behavior in wildland fires. But during wind-driven urban conflagrations, homes are usually a major – if not the main – source of fuel.
…As residents and researchers who have worked extensively on fire in California, we believe the state and its newly elected leadership face a formidable challenge and an opportunity to reinvest in a robust, interdisciplinary approach to wildfire risk reduction that combines the best of both research and practice. It must integrate both new (and potentially controversial) urban planning reforms as well as novel thinking about evacuation alternatives.
California Citrus Network Now Available as Grower Resource
(AgNetWest) Nov. 16
The University of California Cooperative Extension (UCCE) has launched the California Citrus Network as a means to address industry concerns through a collaborative approach. The new website will be another resource available to those involved with citrus production who may have questions or concerns about their operation.
“If they see something out in the field that's unusual, they can snap some pictures with their smartphone or their tablet and they can go onto the forum site,” said UCCE Area Citrus Advisor for Tulare, Fresno, and Madera Counties Greg Douhan. “Let's say you think something is some sort of disease issue, you can go in there and look on that and see if anybody else has been seeing the same thing. Or you can post a question and say, ‘hey I'm finding this unusual situation out in my field, is anybody else seeing this?' so it's just a way to communicate.”
Editorial: Horrifying infernos in California
(Providence RI Journal) Nov. 16
California deals with wildfires on an annual basis. Parts of the state were ravaged earlier this summer. But what has happened this month alone will make 2018 the worst year on record.
Five separate wildfires (named Camp, Nurse, Hill, Woolsey and Peak) in November have burned more than 245,000 acres of land.
…Max Moritz, a wildfire specialist with the University of California, told the AP that there are “so many ways that can go wrong, in the warning, the modes of getting the message out, the confusion ... the traffic jams.” He suggested local officials consider building “local retreat zones” and “local safety zones” in urban communities to protect residents from the deadly wildfires.
See how a warmer world primed California for large fires
(National Geographic) Alejandra Borunda, Nov. 15
…Over the past century, California has warmed by about three degrees Fahrenheit. That extra-warmed air sucks water out of plants and soils, leaving the trees, shrubs, and rolling grasslands of the state dry and primed to burn.
That vegetation-drying effect compounds with every degree of warming, explains Daniel Swain, a climate scientist at the University of California, Los Angeles, meaning that plants lose their water more efficiently today than they did before climate change ratcheted up California's temperatures.
…Changes in precipitation are another factor. California's summer dry season has also been lengthening. Each extra day lets plants dry out more, increasing their susceptibility to burning.
“Usually—or, I don't want to even say usually anymore because things are changing so fast—we get some rains around Halloween that wet things down,” says Faith Kearns, a scientist at University of California Institute for Water Resources in Oakland. But in the past few years, those rains haven't come until much later in the autumn—November, or even December.
