Earth’s Next Ice Age Might Already Be on the Way—Here’s What Scientists Just Discovered
Obliquity (40,000-year cycle): The tilt of Earth’s axis changes between 22.1° and 24.5°, affecting how much sunlight reaches different latitudes. ・Precession (21,000-year cycle): Earth ...

Study Reveals How Earth's Orbit Triggers Ice Ages, And There's One in The Next 11,000 Years
Earth's history is a roller-coaster of climate fluctuations, of relative warmth giving way to frozen periods of glaciation before rising up again to the more temperate climes we experience today.

Green Sahara: African Humid Periods Paced by Earth's Orbital Changes
The main climatic effect of precession is to shift the season when the Earth has its closest pass to the Sun (perihelion) — the so-called precession of the equinoxes. Today, perihelion occurs in ...
Vernal equinox marks the emergence of spring
The Earth’s axis is at right angles to the line from sun to Earth, the sun is directly over the equator and the lengths of ...

The next ice age is coming in 10,000 years — unless climate change prevents it
The key players in these cycles are Earth's obliquity, the precession of its rotational axis and the shape of Earth's orbit around the sun. Breaking space news, the latest updates on rocket ...
