Earth's Core Cooling Faster Than Thought

Earth’s core is cooling 100 degrees Celsius every billion years—much faster than previously thought. This rapid heat loss could weaken or collapse our planet’s magnetic shield, leaving us exposed to solar radiation. Scientists are now investigating how mantle minerals like bridgmanite influence heat flow, which may explain the accelerated cooling. While not an immediate crisis, understanding this process is vital for predicting Earth’s long-term stability. Support the show:Get a discount at https://solipillow.com/discount/dnn.
