While the Milankovitch Cycles operate on timescales far longer than human lifespans, their effects are always at play.

Researches used rhenium as a proxy for fossil carbon in order to quantify the rate at which Earth naturally releases carbon dioxide into the atmosphere and found that high rates of carbon breakdown ...

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 ...

The Lomagundi-Jatuli event, which occurred more than two billion years ago, followed the Great Oxygenation Event and was ...

On its own, Earth would shift toward another ice age in about 10,000 years, scientists say. But humanity's greenhouse gas emissions may have radically shifted the climate's trajectory. Credit: Matt ...

The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the ...

It is not pleasant to imagine that human activity is making the planet uninhabitable, but we typically think of this in terms of greenhouse gases, rising sea levels or acidifying the oceans. We aren't ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

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 may have had fresh, not just salty, water as soon as 600 million years after the planet formed — a mere blink of an eye in geologic time. Researchers analyzed oxygen molecules within ...

It is with a heavy heart that I announce that NASA Earth Science Communications has directed The Earth Observer to conduct an ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...
