Record-breaking heat is already sweeping parts of the country, with temperatures reaching as high as 108 degrees in some areas. This extreme heat, combined with severe thunderstorms and flash flooding, poses a significant threat to tens of millions of people. The West Coast, the Plains, and the Southeast are particularly affected, with daytime highs settling in the 90s and above. The West Coast is also bracing for rising temperatures, with highs climbing to 10 to 25 degrees above normal. This heatwave is not isolated, as severe thunderstorm watches are in effect for portions of Nebraska, Iowa, and Missouri, with an additional 20 million people facing the risk of strong to severe storms. Flash flood alerts are also in place for these areas, with cities like Kansas City, Tulsa, and Wichita at risk. By Sunday, the mid-Atlantic, Appalachians, and Ohio Valley will experience showers and thunderstorms, putting 54 million people at risk. This weekend's severe weather follows a turbulent stretch earlier this week, when severe weather placed 13 million people under flood watches and triggered widespread power outages. Some of these temperature shifts could be linked to El Niño, a natural climate pattern that warms surface temperatures in the tropical Pacific, amplifying the warming already driven by climate change. This raises a deeper question: How will these extreme weather events impact our future, and what can we do to mitigate their effects?
