While Mars doesn't directly control Earth's climate, its gravity subtly influences our planet's orbit and tilt over vast ...

To spread awareness that “climate change isn’t just an environmental issue; it’s a human story woven into the fabric of our civilization’s rise and fall,” Georgetown University historian Professor ...

For billions of years, Earth has been bombarded by tiny particles of rock and metal from space. When these extraterrestrial specks hit the upper atmosphere at hypersonic speeds, they burn and melt ...

Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological records that chronicle our planet’s history. European scientists are ...

The idea that Mars could affect Earth’s climate sounds dramatic, since climate change is usually linked to cars, factories, ...

In an exciting development for climate science, researchers have extracted an Arctic ice core containing an astonishing 1.2 million years of Earth’s climate history. The discovery, reported by the ...

Past and future trends in global mean temperature spanning the last 67 million years. Oxygen isotope values in deep-sea benthic foraminifera from sediment cores are a measure of global temperature and ...

Marc Macias-Fauria is a professor of physical geography at the Scott Polar Research Institute at the University of Cambridge, UK. Ends of the Earth: Journeys to the Polar Regions in Search of Life, ...

Slow orbital changes caused pulses in Earth's oxygen cycle 500 million years ago, which spurred explosions of animal life.

Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...

Paul Wilcox descends into Devil’s Canopy Cave on Prince of Wales Island. An unlikely discovery in a cave on Prince of Wales Island could help scientists understand Earth’s climate history. A small ...
