Our planet has experienced dramatic climate shifts throughout its history, oscillating between freezing "icehouse" periods ...

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational ...

While the Milankovitch Cycles operate on timescales far longer than human lifespans, their effects are always at play. Currently, the alignment of these cycles suggests that Earth should be gradually ...

New simulations show red planet affects Milankovitch cycles that shape how solar energy is distributed on Earth over millions ...

This doesn’t mean Mars causes ice ages on its own. Orbital cycles are only part of the picture. Earth’s oceans, atmosphere, ...

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 ...

Carbon released from Earth's spreading tectonic plates, not volcanoes, may have triggered major transitions between ancient ...

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

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 ...

Climate change also alters nitrogen in soils and plants, shaping food quality, water safety, and pollution risks worldwide.
