Earth’s Core Cooling Faster Than Thought | Venice Beach News

Earth’s core might be cooling faster than we thought, with new research revealing that heat loss has been underestimated—potentially shortening the lifespan of our protective magnetic field. Scientists point to bridgmanite, the most abundant mineral in the lower mantle, whose heat-conducting properties may be weaker than previously believed, causing the core to retain heat longer. While this change unfolds over geological timescales, not overnight, it reshapes our understanding of planetary evolution and could impact how long Earth remains habitable. Using seismic data and advanced simulations, researchers are piecing together Earth’s hidden interior—and what it means for life on our planet and beyond.
