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 ...

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 ...

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 ...

Feb. 11 (UPI) --Scientists have discovered evidence that Earth's carbon cycle and global climate is influenced by periodic changes in the shape of Earth's path around the sun. According to a new study ...

Every 27.5 million years or so, the Earth’s heart “beats.” That’s according to a new study published in the journal Geoscience Frontiers, by a team of geologists who found that our planet goes through ...

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 ...

Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to fluctuate during its most extreme ice age—known as Snowball Earth. During the ...

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 ...
