LA Schools Face Tough Road to Recovery After Wildfires

Breaking News, Climate Actions, Environment
As Los Angeles County students return to school after devastating wildfires, the focus is on more than just rebuilding classrooms. With over 1,000 schools closed and 600,000 students affected, the impact extends beyond lost buildings it disrupts learning, mental well-being, and the stability schools provide. Learning Loss and Emotional Recovery Past disasters show that pushing students back into classrooms too quickly can be counterproductive. Florida reopened most schools just a week after Hurricane Ian in 2022, but experts suggest emotional healing must come before academic recovery. Following Hurricane Helene in 2024, North Carolina sent over 260 counselors to support affected students. Schools integrated recovery into lessons science teachers used water testing kits to analyze...

Los Angeles Fires Leave Lasting Impact on Health, Environment, and Community

Breaking News, Climate Actions, Environment, Fact Check
The flames may have died down, but the aftermath of Los Angeles’ devastating wildfires continues to affect public health, the environment, and daily life. Experts at a recent UCLA Fielding School of Public Health event warned that the city is facing an epochal disaster that has transformed air, soil, and institutions. Air Quality and Health Risks Even miles away from the burn zones, smoke and toxic particles have impacted the air. PM2.5 fine particulate matter from wildfires can lodge deep in the lungs, causing heart and respiratory issues, said Yifang Zhu, a professor of environmental health sciences. Even when air looks clear, volatile organic compounds (VOCs) may linger, making exposure dangerous. Michael Jerrett, an expert in climate and public health, highlighted the severe h...
Flooding After Wildfires LA Faces Growing Risk Amid Climate Change

Flooding After Wildfires LA Faces Growing Risk Amid Climate Change

Breaking News, Climate Actions, Disasters, Environment
In the aftermath of devastating urban wildfires, a rainstorm might seem like a welcome relief. However, fire-scorched landscapes are highly vulnerable to floods, which can bring further destruction. Los Angeles has experienced this repeatedly, from the 1933 Griffith Park Fire to the 2009 Station Fire in the San Gabriel Mountains and the 2018 Woolsey Fire in Malibu. Mitul Luhar, an expert in fluid dynamics and associate professor of aerospace, mechanical, civil, and environmental engineering at USC, is studying these risks. At the City of Los Angeles's Hydraulic Research Laboratory in Frogtown, Luhar and his team have developed a 1:120 scale hydraulic model of a section of the L.A. River to simulate flood scenarios. Luhar explains why floods often follow wildfires and what engineers c...
Climate Change Made LA Wildfires 35% More Likely, Study Finds

Climate Change Made LA Wildfires 35% More Likely, Study Finds

Breaking News, Disasters, Fact Check
Los Angeles witnessed one of its worst wildfire outbreaks in January 2025, and according to a new World Weather Attribution (WWA) report, human-induced climate change played a key role in making the conditions 35% more likely. The fires, which began on January 7 in Palisades and Eaton counties, quickly spread, fueled by dry vegetation and strong Santa Ana winds. Over the following weeks, additional fires erupted in San Diego County, ultimately burning over 57,000 acres and causing 28 deaths. For the first time in history, global temperatures surpassed 1.5°C in 2024. The WWA report warns that if temperatures rise to 2.6°C by 2100, the likelihood of such wildfire-friendly conditions will increase by another 35%. Clair Barnes, a researcher at Imperial College London, emphasized how p...
Rising Debris Flow Risks Dangerous Link Between Wildfires, Rainfall, and Climate Change

Rising Debris Flow Risks Dangerous Link Between Wildfires, Rainfall, and Climate Change

Breaking News, Disasters, Fact Check
Debris flows, fast-moving masses of mud, rocks, and water, are becoming a growing concern in the United States, particularly in areas recently affected by wildfires. A map produced by the U.S. Geological Survey (USGS) highlights high-risk zones near Los Angeles after the Palisades Fire. The model simulates a scenario where 15 minutes of rainfall, at just under 1 inch (24 mm) per hour, could trigger debris flows in vulnerable regions. The landscape itself can create ideal conditions for debris flows. Steep slopes, the presence of clay-rich soil, and silt-sized particles in watersheds are key contributors. Generally, slopes gentler than 23 degrees and lacking fine-grain materials are less likely to experience debris flows. Post-wildfire conditions worsen the risk. Severely burned areas...

Breaking News, Climate Actions, Disasters, Environment
While firefighters continue to battle wildfires in the Los Angeles area, another danger is fast approaching. Rain expected over the weekend of January 25–26 may help extinguish the flames, but it also carries the risk of triggering deadly debris flows in the burned hillsides. These fast-moving torrents of water, ash, and debris can wreak havoc, destroying homes, infrastructure, and lives in minutes. The phenomenon is not new to California. In 2018, the hills above Montecito, scorched by the Thomas Fire, gave way during a storm, unleashing a devastating debris flow that killed 23 people and damaged over 400 homes. Similar events now threaten wildfire-affected areas near Los Angeles, where experts warn that the conditions for another disaster are already in place. When wildfires scorch...
