New research suggests that Earth’s orbital variations—the slow changes in its tilt, axial precession, and shape of its ...

Solar radiation received at low-latitude is principally affected by variations in the cumulative effect of eccentricity and precession ... the climate system (e.g., Milankovitch cycles).

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have matched up specific points in those cycles to the timing of ice ages.

Changes in Earth's orbit have helped pace climatic change for millennia. Scientists are now trying to understand whether - and how - these changes remodeled the landscapes our ancient ancestors ...

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.

In the early 1920s, Serbian scientist Milutin Milankovitch proposed that slight ... the researchers plotted known changes in obliquity and precession over the past 800,000 years.
