(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 ...

Billions of tonnes of carbon are constantly moving through the atmosphere, land and oceans. The ocean carbon cycle is a set of vital processes that helps regulate the Earth’s climate and support ...

If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31.

By 3.6 billion years ago, Mars should have become too cold for liquid water, but something kept the rivers flowing.

The emergence of life on our planet added a new layer to the carbon cycle. As plants grow, they take CO 2 out of the atmosphere, and when they die, it is released again. Animals that consume the ...

The principles of chemical oceanography provide insight into the processes regulating the marine carbon cycle. The text offers a background in chemical oceanography and a description of how chemical ...

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new ...

The carbon cycle orchestrates the exchange of carbon among the atmosphere, oceans, soil and living organisms, playing a crucial role in regulating Earth’s climate and maintaining a delicate ...

It’s a great place to see vintage and classic photography and to discover upcoming and emerging photographers.

Fixing the climate crisis is a vast, world-sized puzzle. But one particularly large piece of this ginormous conundrum is ...

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 ...
