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

Abrupt climate shifts are well documented in Earth's history and are commonly associated with ice-sheet dynamics during past ice ages. However, how similar millennial-scale climate variability could ...

At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the extent to which Mars is quietly tugging on Earth's orbit and shaping the ...

Add Yahoo as a preferred source to see more of our stories on Google. New satellite data reveal Earth’s Northern Hemisphere is absorbing more solar energy than the South, threatening to disrupt global ...

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

The Amazon rainforest is so big that it makes its own climate. As they photosynthesise and transpire, its billions of trees collectively produce enough moisture to form clouds. These, by some ...

Scientists who work on long-term climate patterns usually stay close to Earth. The data is here, the records are clearer, and ...

A new study by UC Davis and Chinese researchers shows how extraterrestrial forces move Earth's climate into a glacial phase both over the last 34 million years and 300 million years. Recent rapid ...

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

Our neighbor Mars would hold a significant influence over Earth's climate. New research indicates that its gravity durably ...

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 ...
