## Resource

Earth’s core is cooling 5 times faster than we thought—dropping 100 degrees Celsius every billion years—threatening the magnetic field that shields us from solar radiation. New simulations and ancient rock data reveal this accelerated chill could weaken or collapse the geodynamo over time, forcing a rethink of planetary stability on geological timescales.
