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

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.

Earth's axis is currently tilted at a 23.5-degree ... For the study, the researchers plotted known changes in obliquity and precession over the past 800,000 years. They also plotted the expansion ...

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

The findings highlight the roles of precession, obliquity, and eccentricity – factors influencing the tilt and movement of Earth's axis, and the shape of Earth's orbit around the Sun – in ...

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 subtle changes in orbit (eccentricity), the planet’s inclination compared to the orbit (obliquity), and the change in the direction of Earth’s rotational axis (precession) were possible ...

All winter long, I have been meaning to write about the little constellation Aries the Ram, and finally, on this last weekend ...

They were able to match these changes with small cyclical variations in the shape of Earth's orbit of the sun, its wobble, and the angle at which its axis is tilted. "We found a predictable ...

precession, and obliquity, which have to do with the shape of the Earth’s rotation, the angle of the Earth’s axis, the angle that the Earth rotates around the sun, and how these things change ...
