Earth’s Core Cooling Fast | California News

Earth’s core may be cooling faster than scientists thought, potentially disrupting the magnetic field that shields us from solar radiation. New research using ancient minerals and computer models suggests rapid cooling could weaken the geodynamo—the engine powering our planet’s magnetic field—by slowing heat flow and altering convection currents in the outer core. If true, this could lead to increased radiation exposure for satellites and life on Earth, underscoring how vital the deep Earth’s dynamics are to planetary stability.
