・Precession (21,000-year cycle): Earth wobbles on its axis, changing the timing of the seasons. These cycles interact in complex ways, sometimes reinforcing each other and at other times working ...

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.

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have ...

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.

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

For many millions of years, our planet has experienced glacial periods followed by warmer periods. A crucial role in these changes might come from the orbital motion of our planet. By studying how ...

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 spring equinox marks the start of astronomical spring. Wherever you are on the planet, the equinox occurs at the same ...

Paleoclimate and archaeological evidence tells us that, 11,000-5,000 years ago, the Earth's slow orbital 'wobble' transformed today's Sahara desert to a land covered with vegetation and lakes.

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a ...
