Research reveals agriculture's surprising role in carbon dioxide fluctuations, driven by nitrogen fertilizer and overlooked ...

(A) Photosynthesis in land plants fixes atmospheric CO2 (inorganic carbon) as organic carbon, which is either stored as plant biomass or in soil, or is decomposed back to CO2 through plant and ...

Jill Warren heads the European Cyclists’ Federation, a Brussels-based nongovernmental organization that advocates cycling to ...

This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

and heterotrophic bacteria. The products of these organisms feed back into the carbon cycle in marine sediments, where they may be consumed by other microbes.

Carbon atoms move around the planet in a process known as the carbon cycle—but really, two carbon cycles are moving together at the same time. Here's how it works: This gecko is part of the fast ...

The overall amount of carbon dioxide in the atmosphere has been steadily increasing, a clear trend linked to human activities and climate change. Less ...

Louisiana’s wetlands are vital carbon storage centers, but destroying them can accelerate harmful emissions that accelerate global warming.

as part of what is called ‘the global carbon cycle.’ A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and ...
