Cycles in the growth and decay of Antarctica's ice sheets once shaped marine biological productivity thousands of miles away ...

Most places on Earth have seasons because our planet is on a tilt as it orbits the sun. But our star also has its own version of seasons that affect life on Earth—and new astronomical research is ...

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 ...

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 ...

A seemingly small planetary neighbor may play a larger role in Earth’s climate than previously thought. Mars is only about half the size of Earth and has roughly one tenth of its mass, making it ...

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 ...

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a new ...
