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,

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.

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,
