Climate change also alters nitrogen in soils and plants, shaping food quality, water safety, and pollution risks worldwide.

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 ...

You probably picture the Earth's annual journey around the Sun as being more or less a circle, but that's only true some of the time. Models have long suggested that our home planet's orbit shifts ...

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 ...

What do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles ...

Dedicated cyclists set different goals to strive for, from cycling 40 miles in a day to cycling 5,000km or around 3106 miles in a year. I love cycling because it’s fun working your legs, hips, and ...

A new study is examining the Earth's carbon cycle in new depth, using diamonds as breadcrumbs of insight into some of Earth's deepest geologic mechanisms. A new study led by a University of Alberta ...
