Geologists find that low-relief mountain ranges are the largest carbon sinks
For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20° Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth must ...

Nearly 2 billion people globally at risk from land subsidence
Land subsidence is a geohazard caused by the sudden or gradual settling (years to decades) of the land surface due to the removal of subsurface material. This can be due to a variety of factors, both natural (such as earthquakes, ...

Researchers provide unprecedented view into aerosol formation in Earth's lower atmosphere
Eighty-five percent of the Earth's air resides in the lowest layer of its atmosphere, or troposphere. Yet, major gaps remain in our understanding of the atmospheric chemistry that drives changes in the troposphere's composition.

How does a river breathe? The answer could lead to a better understanding of the global carbon cycle
Take a deep breath. Pay attention to how air moves from your nose to your throat before filling your lungs with oxygen. As you exhale your breath, a mix of oxygen and carbon dioxide leaves your nose and mouth.
