ZH_5_04 — Precession of the Equinoxes: Hipparchus, Axial Wobble, and the Great Year
The precession of the equinoxes — the slow, continuous westward shift of the equinoctial points (where the ecliptic crosses the celestial equator) along the ecliptic — is one of the most consequential astronomical phenom
E_4_13 — Milankovitch Cycles and Orbital Forcing
Milankovitch cycles are periodic variations in Earth's orbital geometry that modulate the distribution and intensity of solar radiation reaching Earth's surface, driving the glacial-interglacial cycles that have dominate
E_4_11 — The Holocene Climate Optimum and Mid-Holocene Transition
The Holocene Climate Optimum (also called the Holocene Thermal Maximum or Hypsithermal) designates a prolonged warm interval roughly spanning 9,000–5,000 years before present, during which Northern Hemisphere summer temp
O_5_05 — Ice Ages and Milankovitch Cycles: Orbital Forcing of Climate
Ice ages — periods when massive continental ice sheets expand to cover large portions of Earth's surface — are among the most dramatic climate events in the planet's history. The Quaternary glaciation (beginning ~2.6 mil
