Throughout Earth’s long and dynamic history, the climate has shifted dramatically. Ice ages have come and gone, shaping the planet and leaving scientists and historians alike wondering about their ...

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 ...

How does Mars influence Earth’s climate cycles? This is what a recent study published in the Publications of the Astronomical Society of the Pacific hopes to address as a trio of researchers from the ...

Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to fluctuate during its most extreme ice age—known as Snowball Earth. During the ...

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 ...

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, ...

Mars' distant orbit may have more of an impact on our planet than we first thought. The interaction between Earth and Mars's gravitational influences may be linked to a 2.4-million-year cycle of ocean ...

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position ...

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 ...

Our existence is governed by natural cycles, from the daily rhythms of sleeping and eating, to longer patterns such as the turn of the seasons and the quadrennial round of leap years. After looking at ...

The annual clock of the seasons – winter, spring, summer, autumn – is often taken as a given. But our new study in Nature, using a new approach for observing seasonal growth cycles from satellites, ...
