Episode Details

A record-breaking, multi-week heat wave is barreling across the U.S., with temperatures soaring 15-25°F above normal—even at night, making it dangerously intense. A massive high-pressure dome could blanket two-thirds of the country, pushing triple-digit highs and shattering overnight records. Scientists call it “remarkable” for its scale, duration, and intensity, linking it directly to climate change. While El Niño’s role is unclear, fossil fuel emissions are making these extremes hotter, longer, and more widespread—threatening health and fueling wildfires as the nation braces for a scorcher that could last into the month.
