MOLINE, Ill. — It was in the 1920s that a Serbian geophysicist, Mulitin Milanković, theorized that variations in Earth's tilt and wobbling about its axis impact the amount of energy being received ...

Simulation results show that Mars, despite its similar size to Earth, has a considerable influence on the Milankovitch cycles ...

HOUSTON, Texas -- Houstonians showed up in droves to help make an environmental impact at the 16th annual ABC13 Earth Day E-Cycle Drive. A steady line of vehicles flowed through CompuCycle's Spring ...

Earth’s climate has never been static. It shifts between warm interglacial periods and deep freezes, driven by complex interactions between the atmosphere, oceans, and even Earth’s orbit around 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 ...

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 ...

Earth's seasons look very different at locations not far from each other, 20 years' worth of satellite data reveals. Earth's seasonal cycles can vary dramatically across short distances, even at the ...

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 ...

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 ...
