SAN DIEGO, Calif. — Scientists are harnessing a not-so-secret weapon in the fight against climate change: plants.“Plants are very good at one thing and that is to catch carbon dioxide out of the air and using the power of the sunlight to fix it to make into bio-materials," said Wolfgang Busch.A plant scientist and professor at the Salk Institute for Biological Studies, Busch is co-director of the Harnessing Plants Initiative (HPI). "Plants are superheroes," said Busch. “They can do what nothing else can do, no technical solution at that scale, to catch a lot of carbon dioxide and fix it.”Yet, humanity is still losing the climate change battle. After decades of burning fossil fuels, the planet continues to warm, with natural disasters growing more frequent and intense.Busch says while plants suck up carbon dioxide, some of it is released back into the atmosphere.“How can we actually make plants better in not only catching the carbon dioxide but keeping it in the soil?” said Busch.That's the challenge his team set out to solve, working to identify genes that help plants store more carbon underground. “Trying to enhance their superhero capability even more," said Busch. They’re developing plants with deeper, more massive roots, rich in a substance called suberin, a natural carbon storage device. Combined, these traits supercharge the plants, allowing them to absorb more carbon dioxide and keep it locked underground.“We think it has all the characteristics of something that can make a huge impact addressing this very difficult question, how to draw down carbon dioxide from the air and store it," said Busch. These climate fighting traits can then be transferred to the world’s six most prevalent crops: corn, soybean, canola, rice, wheat, and sorghum.By tapping into the existing agricultural supply chain, researchers say more than 75 percent of the world’s cropland could be converted into carbon storage.“We think in 10 to 15 years, after partnering with different stakeholders, seeds will be available to farmers at scale to plant the first carbon-sequestering crops,” said Busch.Busch says one of their top priorities is ensuring the initiative will benefit farmers, aiming to produce plants that will equal, if not exceed, the yields of current crops. And storing carbon underground not only protects the atmosphere but enriches the soil, making it more fertile.Busch says the plants will also be more resilient to climate-related threats, with an enhanced ability to hold water, resist pathogens, and tolerate stress"Gives us hope that we can make a huge impact; if we can develop crops that are better at storing carbon for longer and if these crops are adopted at a very large scale," said Busch.The initiative has received over million in grants, with the most recent boost from Amazon CEO Jeff Bezos donating million. 2867

SAN FRANCISCO (AP) — A man who illegally demolished a San Francisco house designed by modernist architect Richard Neutra was ordered this week to rebuild it exactly as it was.The city Planning Commission also ordered Ross Johnston to add a sidewalk plaque telling the entire saga of the house's origins in the 1930s, its demolition and replication.It's not known whether he will follow through. A call and email message seeking comments from Johnston's lawyer has not been returned.RELATED: What an affordable home in San Diego looks likeJohnston had received permission only to remodel the two-story house he bought for .7 million in 2017 with a design that would have largely kept the first floor intact, the San Francisco Chronicle reported .Instead, everything but the garage door and frame of the house was knocked down.Johnston later applied for a retroactive demolition permit and asked to build a new three-story house that would expand the size from 1,300 to nearly 4,000 square feet (121 to 372 square meters).Johnston said he wanted to move his family of six into the larger home."I have been stuck in limbo for over a year," he told the seven-member commission.RELATED: Home prices in San Diego County up 9 percent year-over-yearHis attorney Justin Zucker argued that the house's historic value had been erased over time because of a 1968 fire and a series of remodels in the 1980s and 1990s.The house in Twin Peaks, known among architecture buffs as the Largent House, was the Austrian architect's first project in San Francisco.Planning Commissioner Kathrin Moore said she is confident that a replica could be "executed beautifully in a way that would be consistent with the home's original expression." 1727

SAN FRANCISCO (AP) — In his 20 years as a paramedic, Mickey Huber assisted in two emergency deliveries. But to him, the most memorable birth is the one that didn't happen on his watch.Huber was helping people evacuate from the terrifying wildfire that tore through the Northern California town of Paradise on Nov. 8 when he heard on the scanner about a pregnant woman going into premature labor.Anastasia Skinner's baby wasn't due for another month, but she began to feel contractions as she grabbed her mother's two dogs and raced to escape the fast-moving blaze. The flames had already hit her car by the time she fought the panic-driven traffic jam out of town and reached a gas station, honking the horn and screaming for help."I knew I wasn't going to make it," Skinner, 25, said during a phone interview on Friday. "I called my husband and told him goodbye, tell all the kids I love them and make sure they remember me."A motorcyclist who saw Skinner in distress flagged a police officer who helped her move to the back seat of her Honda Pilot. Several women who were stuck in the traffic jam brought her blankets and pillows, A retired fire chief came to her aid and someone requested a helicopter to airlift her to the hospital.Huber, the assistant chief of operations for Butte County Emergency Services, was two miles away but had to get through 30 minutes of gridlock to get to Skinner. When he arrived and evaluated her condition, he knew she couldn't wait much longer for a helicopter."The smoke was thick, and the winds were blowing. The helicopters were having a hard time fighting the fire let alone airlifting patients," Huber said.Because Skinner was having a high-risk pregnancy after suffering two miscarriages and other complications related to an inherited disorder, Huber said she may not have made it if she went into full-blown labor.He arranged a caravan that included three police vehicles to rush Skinner to an ambulance. Then he jumped in the back seat, where he kept her calm until she reached a hospital where her labor was stopped."He was sweet. He told me, 'I'm a guy. I don't know what this feels like for you, but I'll try to help you get you through it,' " Skinner said. "Then he would yell at people outside of the car, waving his hat and telling them to get out of the way.""My goal was to keep her breathing and get her down the hill," Huber said. "Two of my ambulance crews were trapped by the fire moments before I got to Anastasia so there was a lot of doubt, a lot of worry."Skinner said a doctor later told her smoke inhalation put her body under stress and triggered the contractions.On Dec. 12, more than a month after the fire began, Skinner gave birth via C-section to a full-term, healthy girl and named her after the man she believes saved her life."She's a blessing in every way including what happened at the Camp Fire," she said about her daughter, Zoele (rhymes with Noel) Mickey Skinner.Skinner and her husband, Daniel, have three other children, ages 8, 6 and 4.After getting Skinner to the ambulance, Huber helped with the mass evacuation until the next day. He said he was shocked and honored when he learned the baby was named after him."That day was full of a thousand different emotions but that is the strongest memory of the day for me," Huber said.More than 50,000 people in Paradise and the neighboring communities of Magalia and Concow were forced to quickly flee the towering, wind-driven flames that burned an area about the size of Chicago — 240 square miles (622 square kilometers) — and became the deadliest U.S. wildfire in at least a century. At least 86 people were killed and 14,000 homes destroyed.Skinner and her husband, Daniel, lost their home; her mother lost hers too."All of our history and what we were as a family, everybody knowing your name and all the things about being in a small town are just gone," Skinner said.When her children get sad about the things they lost in the fire, she said she reminds them to count their blessings, including the baby sister who made it alive."All of us, including our animals are out. Everybody we know is safe," Skinner said. "We can replace all the stuff in our house, but we can't replace each other." 4235

  

SAN FRANCISCO (AP) — After successive years of devastating wildfires, California's fire agency announced a plan Tuesday that would dramatically increase logging and other forest management efforts with the help of the National Guard.The California Department of Forestry and Fire Protection released a list of 35 priority fuel-reduction projects it wants to start immediately across the state over roughly 90,000 acres. That's double the acreage the agency aimed to cover in the current fiscal year, CalFire Deputy Chief Scott McLean said.The agency is also seeking National Guard assistance to coordinate the work. McLean said it was the first time he could recall turning to the National Guard for help with clearing trees and vegetation.RELATED: San Diego County areas on Cal Fire list of high-priority fire projects"It just goes to show you how committed everybody is," he said.The deadliest U.S. fire in a century destroyed much of Paradise — a city of 27,000 people in Northern California — in November 2018 and killed 86 people. California also experienced devastating wildfires in 2017, including a blaze that killed 22 people and destroyed more than 5,500 structures around the wine country city of Santa Rosa.Republican President Donald Trump has repeatedly criticized California's Democratic officials for not doing a good enough job managing its forests and has threatened to cut off California's federal disaster funding.RELATED: Southern California wildfire burn zones on alert during stormThe 35 projects are based on input from local Calfire units and would reduce wildfire risk to more than 200 communities, according to Calfire. They include removing dead trees, clearing vegetation, and creating fuel breaks, defensible spaces and ingress and egress corridors.The projects prioritize communities at high risk from wildfires but also with significant numbers of vulnerable groups such as the elderly or poor. They include work around the city of Redding, which was also devastated by wildfire last year, and in Butte County, where Paradise is located.An estimated 15 million acres of forest land in California are in need of thinning or other restoration work, so the 35 projects are just a start, Calfire officials said. The agency wants to establish incident bases with the National Guard close to vulnerable communities to coordinate fuel-reduction projects.RELATED: PG&E: Company's equipment may have ignited Camp FireKathryn Phillips, director of Sierra Club California, said many of the recent fires were driven by high winds, so clearing trees and vegetation is not the solution. Calfire should focus more on clearing brush around homes and ensuring their roofs and attics are safe from flying embers, she said."We need to make sure we're doing the things that we know will protect homes," she said.Calfire does call on officials to identify options for retrofitting homes as part of its recommendations released Tuesday. 2954

  

SAN DIEGO (KGTV)-- On most days at the North Side Shack in Point Loma, you'll find Pamela Olivera. She opened the now-thriving shop four years ago."If you're really motivated, if you really enjoy something, wanna do something, you only live once," said Olivera of the gamble that paid off.While she always had a passion for cooking, it wasn't always how she made a living. Olivera was once a paralegal. She thought was a good job for a single mother of three, but it wasn't a job she loved. So, she decided to change that.  She went to the San Diego Workforce Partnership location in Chula Vista, where she found a program that would give her money to retrain for a new career. In her case, it was culinary school. "For me, they offered me a ,000 grant, the program was ,000. That's a third of the cost of the school," said Olivera.The partnership provides a long list of resources for job seekers depending on their needs. The service is free. It's a valuable tool Olivera says more people should utilize.Other resources available include career counseling, job searches, typing certificates and Microsoft Word classes. The San Diego Workforce Partnership also provides labor market information to learn what industries are hiring for what skills.Get more information about San Diego Workforce Partnership here.  1356
