Forest trees growing in air containing higher levels of carbon dioxide (CO2) radically change the way they "cycle" nitrogen, ...

The ocean absorbs roughly a quarter of humanity's carbon dioxide emissions each year. Understanding how that happens, and how ...

Researchers at UC San Diego’s Scripps Institution of Oceanography have created a more accurate model of global carbon cycling. The model better accounts for the contributions of Earth’s terrestrial ...

A new study has revealed for the first time that ancient carbon, stored in landscapes for thousands of years or more, can find its way back to the atmosphere as CO₂ released from the surfaces of ...

Mesopelagic fish, long overlooked in ocean chemistry, are now proven to excrete carbonate minerals much like their shallow-water counterparts—despite living in dark, high-pressure depths. Using the ...

Excess carbon dioxide emitted by human activities—such as fossil fuel burning, land-use changes, and deforestation—is known as anthropogenic carbon dioxide. Approximately thirty percent of this ...
