Milankovitch cycles
Milankovitch cycles are the periodic changes in Earth's orbit and axial tilt that affect the distribution of solar radiation on the planet, driving long-term climate variations. These cycles, spanning tens of thousands of years, are key to understanding ice ages and global temperature shifts, with modern scientists using them to contextualize human-induced climate change against natural patterns.
Did you know?
One astonishing aspect is that the 41,000-year cycle of Earth's axial tilt has directly correlated with the onset of at least 50 major ice ages over the past 2.5 million years, as revealed by Antarctic ice core data. This means the very timing of human evolution and migration out of Africa may have been shaped by these subtle orbital dances, potentially delaying or accelerating key developments in our species' history.
