Wildfires devastate communities, ecosystems, and lives and they’re getting harder to stop. But what if firefighters could spot a blaze in its earliest moments, before anyone even calls 911?   In this episode of Tools and Weapons, Microsoft Vice Chair and President Brad Smith travels to California to meet Deputy Fire Chief Zachary Wells and Dr. Neal Driscoll, a UC San Diego professor working together to form ALERTCalifornia, one of the most ambitious early-warning and situational awareness systems in the world.   By combining strategically placed mountaintop cameras, cloud computing, and AI-powered change detection, ALERTCalifornia acts like a region-scale smoke detector, monitoring thousands of square miles and surfacing only the signals that matter. The result: faster response times, better decisions in the first critical minutes, and safer outcomes for both firefighters and the communities they protect.   This is a story about partnership, between firefighters, scientists, and data scientists, and about how AI doesn’t replace human judgment, but sharpens it. From early detection to prediction, and from California to the rest of the world, this episode shows what’s possible when technology is designed with one goal in mind: protecting life.
