How Our Violent Sun Drives The Earth’s Climate

How Our Violent Sun Drives The Earth’s Climate


This NASA video is actually a clip from a longer documentary playing at the Smithsonian, called Dynamic Earth: Exploring Earth’s Climate Engine, and its visualisations of wind and ocean currents were created using the agency’s powerful climate simulators. The Earth’s spinning molten core actually produces a strong magnetic field that deflects most of the sun’s harmful ejections, and what energy that isn’t blocked or reflected by clouds and ice serves to heat the planet and generate the weather systems that let us grow food. So in a way, the sun’s our biggest enemy and our biggest ally at the same time. Even if today it feels like it’s doing more harm than good. [Universe Today via Geekosystem]
