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 ...

As an essential material for the survival and reproduction of almost all aerobic organisms, oxygen is closely related to the formation and development of complex organisms. A recent review provides a ...

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 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 ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...

How does climate change influence the planet’s nitrogen cycle? This is what a recent study published in Nitrogen Cycling hopes to address as a team of researchers investigated climate change’s impact ...

Mars, despite being tens of millions of miles away, may play a larger role in Earth’s long-term climate cycles than previously thought, according to research published Sunday. The study, which ...

Ultimately, to understand how the Earth’s carbon cycle works is to appreciate the human influence currently impacting it. Getty Images, James Cawley This is the second in a five-part series written by ...

Scientists who work on long-term climate patterns usually stay close to Earth. The data is here, the records are clearer, and the risks are immediate. A new study shifts that focus slightly outward.
