EP 195 - Extreme Weather Events: Fire & Winds & Coping with Dual Threat of Wildfires

Wildfires, though not a weather phenomena, are linked to weather, often ignited by lightning, and capable of generating their own weather patterns. Global incidents in Chile, Australia, California, and Canada underscore the destructive impact of uncontrolled fires. In the American West, widespread wildfires are becoming the norm, with increasing frequency since the 1980s. The U.S. witnessed over 9.8 million acres burned in the past year alone. While wildfires play a natural role in ecosystem renewal, they also pose threats such as habitat destruction, air pollution, and the release of greenhouse gases. 

Wind significantly influences wildfires, contributing to fire whirls and firestorms. Fire whirls are spinning columns of hot air carrying flames, while firestorms generate winds and thunderstorms, creating their weather systems. Wind directs the fire's spread, and its speed determines the fire's pace, shape, and intensity. Different fire behaviors result from wind dynamics. 

Wildfires have increased in frequency and intensity since the 1980s, and are projected to continue rising. Some Western ecoregions have year-round fire seasons. Wildfires release carbon dioxide, a greenhouse gas that contributes to global warming. 

The combination of fire and wind presents risks to lives, property, and ecosystems, necessitating awareness and preventive measures. Recommendations include creating defensible spaces around homes, using fire-resistant materials, adhering to fire restrictions, staying informed about fire and weather conditions, and following authorities' instructions during wildfires. Human activities and climate change can exacerbate wildfires, emphasizing the importance of understanding fire and wind dynamics and implementing preventive measures to mitigate their impact. 

Join Host Bernice Butler as she explores and unpacks Fire & Winds at the intersection of Wildfires with Deepti Singh and Jennifer Marlon.
