For decades, scientists have suspected that Earth’s changing orbit plays a crucial role in long-term climate shifts. These orbital variations, known as Milankovitch cycles, describe how Earth ...

For millions of years, Earth's climate has been governed not just by carbon or oceans - but by the shape of its orbit. Known as Milankovitch Cycles, these long-term astronomical patterns influence ice ...

As we celebrate Earth Month, we are kicking off a series of retrospectives on National Academies reports and activities ...

La Nina, the natural cooling flip side of the better-known and warmer El Nino climate phenomenon, has dwindled away after ...

A new study reveals significant changes in the global freshwater oxygen cycle. Rivers, streams, lakes, and reservoirs aren’t just beautiful features of the landscape, they’re vital to life on Earth.

Around the globe, rising temperatures stoked by climate change ... moves between the Earth and its atmosphere. But that system — called the hydrological cycle — is speeding up as global ...

In the new study, Seo and his colleagues extend this record back to 1979 — and provided the first “evidence of a permanent shift in Earth’s hydrological cycle due to climate change,” said ...

As climate change melts ice sheets and glaciers, water is being redistributed across the globe — and could end up moving the point of Earth's axis of rotation.

Terrestrial carbon cycle dynamics remain one of the greatest sources of uncertainty in climate projections, with diverging estimates of ecosystem carbon uptake, affecting the accuracy of Earth system ...

It also represents an interactive carbon cycle, including methane, to simulate how the Earth system responds to different climate forcings, such as human-made greenhouse gas emissions. Climate ...

In 2025, Earth Day falls on Tuesday, April 22. The annual recognition is a time when the world comes together to raise awareness about climate change, pollution, endangered species and how to be ...

Research co-led by the University of Maryland reveals that drought and increased temperatures in a CO2-rich climate can dramatically ... Oak Ridge National Laboratory ... Earth's Third Pole ...
