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: While Earth's atmosphere 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 ...

Rivers, lakes and wetlands are important factors for climate change, which should have a place in conceptual models of the global carbon cycle. A broader concept of a 'boundless carbon cycle ...

These land-based water bodies bury, cycle and emit significant ... hydrology and primary productivity also explained a considerable part of the variance in lake carbon dioxide concentrations.

Carbon dioxide concentrations were set at 400 µatm to simulate present-day ambient levels and 700 µatm to reflect projected acidification under moderate-emission scenarios. Results showed a ...
