Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds ...

Simulation results show that Mars, despite its similar size to Earth, has a considerable influence on the Milankovitch cycles.

What do the Gulf of Mexico's "dead zone," global climate change and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles ...

Earth is closer to the sun at some times of year than at others, with the time of closest approach shifting over a period of 22,000 years. This affects Earth's climate, including ice ages, but a team ...

A series of severe frosts during the early days of the Earth could have provided the ‘spark’ needed to kickstart life, according to a new study. Researchers have discovered that repeatedly freezing ...

Over the past couple million years, a rhythmic pattern of climate changes have been driven by cycles in Earth’s orbit. These cycles affect the sunlight reaching the Earth, altering seasonal patterns ...
