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.

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural cycles.

Earth’s climate has long been shaped by subtle but powerful shifts in its orbit. These slow, predictable changes drive the planet in and out of ice ages over tens of thousands of years. A recent study offers new insights into this natural climate rhythm,

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests the onset of the next ice age could be expected in 10,

Glacial cycles aren’t random; they follow a predictable rhythm dictated by Earth’s orbit. A study analyzing climate records from the past 800,000 years found that specific alignments of Earth's wobble,
