Earth's slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by researchers from China, Belgium, and Austria shows that these orbital motions can ...

Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past.

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if ...

The earth (and humanity) would be very different without our smaller red neighbor. In A Nutshell Computer simulations show ...

Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...

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 ...

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 ...
