Earth recorded its hottest year ever in 2024, with such a big jump that the planet temporarily passed a major climate threshold, several weather monitoring agencies announced Friday. Last year's global average temperature easily passed 2023's record heat ...

Humanity has reached the first Earth system tipping point, the widespread death of warm-water coral reefs, marking the beginning of irreversible planetary shifts. As global temperatures move beyond 1.
