Earth's core is cooling faster than expected, which could lead to disastrous in the future? #shorts

A new research shows Earth's core is cooling faster than they previously thought and could have major implications for the future of the earth.
Current research has shown that bridgmanite, is found in large quantities between the core and mantle layers—which is called the Core-Mantle-Boundary (CMB.)
Scientists mentioned they studied bridgmanite at high temperatures and pressures found in the CMB. They discovered that it is about 1.5 times more conductive of heat than previously thought.
When heat from the Earth's core transfers to the surface, it is due to the convection currents in the liquid rock at the mantle. Convection currents also account for shifting crust plates- a widespread phenomenon that causes earthquakes and volcanoes.
After the heat transfer ceased, the last magnetic field on Mars had also faded away long ago. This left it looking similar to Earth's dead, arid wasteland.
