Milankovitch Cycles
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Long-term climate variations on Earth (glacial and interglacial periods) are primarily determined by periodic changes in Earth's orbital parameters (eccentricity, axial tilt, precession). These subtle astronomical parameter changes dictate the amount of solar radiation Earth receives.
SCAFFOLDING EFFECT
Reduce cognitive load
The fate of ultra-long cycles. Many of what we perceive as "current trends" or "human impacts" may, on a ten-thousand-year scale, be just ripples in a cosmic cycle. Understanding the grand cycle allows us to remain calm about short-term fluctuations.
Anchor fast decisions
Periodic changes in Earth's orbital eccentricity, axial tilt, and precession alter the distribution of solar radiation, driving glacial-interglacial climate cycles on a ten-thousand-year timescale.
