Earth’s elliptical path around the Sun does more than keep the planet in a stable orbit. Because that path is not a perfect circle, the distance between Earth and the Sun changes throughout the year, ...

Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...

A strip of cool water stretches west from South America along the equator, helping set the pace for some of the planet’s most important weather swings. That Pacific “cold tongue” helps steer the El ...

Add Yahoo as a preferred source to see more of our stories on Google. New research links Earth’s orbital wobble to 4,000–5,000-year climate swings during a hot, ice-free Cretaceous period. (CREDIT: ...

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural cycles. That's according to a new study published Thursday in Science, which ...

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 climates trajectory. (Santa Barbara, ...

Asteroid 2025 PN7 orbits Earth similarly to the moon but is a quasi-satellite. The asteroid poses no threat and will never come closer than 4 million kilometers to Earth. Other quasi-satellites ...

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past. During the last Ice Age, Greenland warmed by as much as 16°C over short ...
