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 ...

Human beings have a relationship with the seasons that is nourished by a close connection with Mother Earth. Our bodies are ...

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 ...

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 ...

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 ...

Cycles in the growth and decay of Antarctica's ice sheets once shaped marine biological productivity thousands of miles away in the subtropical ocean, according to new research led by scientists at ...

The hydrological cycle is a fundamental natural process for keeping Earth’s operating system intact. Humanity and civilization are intimately dependent on the water cycle, but we have manipulated it ...

It is not pleasant to imagine that human activity is making the planet uninhabitable, but we typically think of this in terms of greenhouse gases, rising sea levels or acidifying the oceans. We aren't ...
