car·bon di·ox·ide cy·cle

, carbon cycle
the circulation of carbon as CO2 from the expired air of animals and decaying organic matter to plant life where it is synthesized (through photosynthesis) to carbohydrate material, from which, as a result of catabolic processes in all life, it is again ultimately released to the atmosphere as CO2.

carbon cycle

n.
1. Physics See carbon-nitrogen-oxygen cycle.
2. Ecology The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs—the atmosphere, oceans, and living organisms.

carbon cycle

A general term for the flux of CO2 from the point of fixation by photosynthesis to its release into the atmosphere by anthropogenic activities.

car·bon di·ox·ide cy·cle

, carbon cycle (kahr'bŏn dī-oks'īd sī'kĕl)
The circulation of carbon as CO2 from the expired air of animals and decaying organic matter to plant life where it is synthesized (through photosynthesis) to carbohydrate material, from which, as a result of catabolic processes in all life, it is again ultimately released to the atmosphere as carbon dioxide.

carbon cycle

The important biological cycle in which carbon in carbon dioxide in the atmosphere is taken up by plants, incorporated, by photosynthesis, into carbohydrates which are eaten by animals, and the carbon then oxidised and finally returned to the atmosphere as carbon dioxide waste gas.

The new view, however, indicates that a slow-down in mixing will also diminish the PIPs, which are vital to the ocean carbon cycle as "very efficient export mechanisms that get the particles nice and deep where the carbon can be stored longer," Weber said.
The workshop identified five major modeling challenges common to the scientific communities working on the terrestrial and ocean sides of the carbon cycle, as summarized below.
The carbonate-silicate cycle the authors are referring to is the evolution of rock through processes like sedimentation and weathering, a substantial part of the way carbon cycles through the global ecosystem.

The second edition contains five new chapters that explore recent advances in the field like DOM dynamics in the Mediterranean Sea, factors that control long-term stability of DOM, DOM composition revealed by new technologies, fate of terrigenous DOM in the marine environment, and contributions of DOM to the carbon cycle of the ancient ocean.
The orbiting observatory is NASA's first satellite mission dedicated to studying carbon dioxide, a critical component of Earth's carbon cycle that is the leading human-produced greenhouse gas driving changes in Earth's climate.
The detailed mechanisms of how the oceans contribute to this global carbon cycle at the microscopic scale, and which microbes have a leadership role in the breakdown process, are complex and convoluted problems to solve.

"I think it's amazing that there are a near- infinite number of these conversations going on in the ocean right now, and they are affecting Earth's carbon cycle."
The report provides the most up-to-date information on greenhouse gas emissions, the global carbon cycle, sea level rise, future climate projections, and more.
A biomass plant can accelerate significantly the carbon cycle of plant life - burning biomass today will contribute to climate change, while leaving a forest standing would, barring a catastrophic wildfire, keep the carbon locked up for generations.
