Ancient North American droughts were driven by Earth’s orbital shifts, study from the University of Helsinki finds.

These orbital variations, known as Milankovitch cycles, describe how Earth’s path around the Sun changes over tens to hundreds of thousands of years. These changes influence the amount of solar ...

New research suggests that Earth’s orbital variations—the slow changes in its tilt, axial precession, and shape of its orbit—may influence the timing of massive volcanic eruptions ...

He explains why this causes temperatures to fall and how this can be exaggerated by the changing tilt of the earth. Use to introduce the concept of Quaternary climate change, either to inform ...

Climatic changes of the last 18,000 years ... Monsoon climate of the early Holocene: Climate experiment with the Earth's orbital parameters for 9000 years ago. Science 214, 59-61 (1981).

Above the Earth’s surface there are many orbital planes and no pesky oceans to prevent millimeter and centimeter-sized cars from being spaced out there. This gives a rough idea of just how ...
