WebApr 13, 2024 · The mantle influences the magnetic field by imposing a pattern of cooling that controls the dynamics of fluid flow at the top of the outer core. Thermal interactions between Earth’s core and mantle provide the power that maintains the geomagnetic field. However, the effect of these interactions on magnetic field behaviour remains uncertain. Webis no longer warming, and is now cooling. Here we show that periods of no trend or even cooling of the globally averaged surface air temperature are found in the last 34 years of the observed record, and in climate model simulations of the 20th and 21st century forced with increasing greenhouse gases. We show that the climate over the 21st ...
