Extremely Hot, Humid Weather Could Kill a Person Far More Easily Than We Thought

The human body might not cope with nearly as much heat and humidity as theory predicts. One of the first studies to directly assess humid heat stress among young people has found that when humidity is at an absolute max, the upper limit of human adaptability is just 31°C (87 °F).   That’s four degrees … Read more

An Asteroid Predicted to Hit Earth in 2023 Has Turned Out to Be Safe
