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

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

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 ...

Mars is about half Earth’s size and roughly a tenth its mass — not really the sort of planet you’d expect to leave ...

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

Researchers uncover how Mars affects Earth’s orbit, offering new insight into the planetary forces behind ice ages.

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 ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

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

If Earth's life survives the Anthropocene, it will eventually face another existential threat from space. As the Sun brightens with age, it will inevitably interfere with our planet's finicky carbon ...
