Breaking News, Climate Actions, Disasters
As LA wildfires rage on, high winds are expected to worsen conditions, amplifying the destruction and raising new concerns about drinking water safety. Last week, Pasadena Water and Power issued its first-ever "Do Not Drink" notice to a third of its customers, citing the risk of toxic chemicals infiltrating the water supply after infrastructure damage. Although the advisory has since been lifted for most areas, the incident highlights the hidden dangers urban fires pose to water systems. Unlike wildfires in forests, urban fires wreak havoc on critical infrastructure. Andrew Whelton, a Purdue University professor, explains that ash, soot, and debris can enter water systems when pressure drops during a fire. Compounds released from burning synthetic materials are especially harmful, even ...

Mining Impact on Rivers Flood Risks in Dynamic Channels

Breaking News, Climate Actions, Environment, Thoughts & Talks
Rivers are often subjected to human interventions such as structural confinement and aggregate mining, which significantly alter their natural flow and topography. A recent study conducted on the gravel-bed Bislak River in the Philippines sheds light on how these activities influence river morphology, hydraulics, and flood risks. Using repeat, system-scale, high-resolution topographic surveys, researchers examined annual morphological changes in the Bislak River. They coupled this data with two-dimensional hydraulic modeling to simulate the impacts on flood risk. The findings highlight a complex interplay between human actions, sediment dynamics, and river hydraulics. Key Findings Sediment Dynamics and Topography Aggregate mining was found to export sediment from the river, lea...

January 2025 has brought devastating wildfires to the Los Angeles area with investigators racing to uncover their origins. The fires, driven by fierce winds, have ravaged thousands of homes, leaving communities in ruins. Early findings suggest that human activities, utility infrastructure, or equipment failures may be to blame, as lightning was absent during the outbreaks. Human activities play a significant role in igniting these blazes. The deadly 2023 Maui fire, for example, began with a broken power line, while California’s largest fire in 2024 started when a burning car was pushed into a ravine near Chico, destroying over 700 structures. This year’s fires are yet another reminder of the devastating impact of human-related ignitions. Wildfires thrive on three elements: conduc...

Breaking News, Disasters, Environment
Children born in 2020 are projected to experience double the number of wildfires over their lifetimes compared to those born in 1960, according to recent studies. In regions like California, wildfires have become a common occurrence during the summer and fall seasons, releasing harmful particulate matter (PM₂.₅) into the air that poses significant health risks. Wildfire-produced PM₂.₅ can penetrate deep into the lungs, causing immediate respiratory issues. While short-term exposure is linked to acute health problems like asthma, the long-term effects of repeated exposure are still unclear. A major challenge is accurately measuring wildfire-related PM₂.₅ exposure, as the intensity of pollution can vary drastically from day to day. Current methods of measuring annual average PM₂.₅, whi...
When Wildfires Create Their Own Weather: Understanding Extreme Fire Situations

When Wildfires Create Their Own Weather: Understanding Extreme Fire Situations

Breaking News, Disasters
Wildfires are becoming increasingly destructive, and in some cases, they can become so intense that they create their own weather systems. This phenomenon, seen in the massive Park Fire near Chico, California, in summer 2024, highlights the complex interplay between wildfires and atmospheric conditions. Here's a detailed look at how wildfires can influence weather and the implications of these extreme fire events. Wildfires can start with a simple spark, ignited by lightning or a downed power line, and quickly spread in hot, dry, and windy conditions. As vegetation burns, it releases a significant amount of heat, which causes the air near the ground to rise rapidly. This rising hot air, much like a hot air balloon, creates its own wind patterns as cooler air rushes in to replace it. ...
