The Next Ice Age Was Supposed Be In 10,000 Years. Human Interference Has Now Changed That Forever Earth’s climate always followed a natural rhythm that cycled through periods of warmth and cold over tens of thousands of years.

Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of these parameters' cycles and clues hidden at the bottom of the ocean.

Earth’s climate has never been static. It shifts between warm interglacial periods and deep freezes, driven by complex interactions between the atmosphere, oceans, and even Earth’s orbit around the Sun.
