The most deadly heat waves so far have been dry heat waves. But a new threat is rising: humid heat waves, aka wet-bulb events. Scientists have identified wet-bulb temperatures where sweat can’t evaporate fast enough to cool the human body. And once this threshold is crossed, it doesn’t matter how much shade or water you have: you won’t survive without environmental cooling like air conditioning. In this episode of Weathered, we break down: What wet-bulb temperature actually means, why it’s so dangerous, what areas will be affected, and why air conditioning, while essential, isn’t enough.\n
