carbon cycle, definition of

All parts (reservoirs) and fluxes of carbon. The cycle is usually thought of as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels). The annual movements of carbon, the carbon exchanges between reservoirs, occur because of various chemical, physical, geological, and biological processes. The ocean contains the largest pool of carbon near the surface of the Earth, but most of that pool is not involved with rapid exchange with the atmosphere.

• Settled Science Springs a Leak: Rivers Reveal the Carbon Cycle’s Dirty Secret
  To call climate science “settled” in the wake of this paper is not just intellectually lazy—it’s laughable. It's the scientific equivalent of declaring victory halfway through a chess match while ignoring that your queen is missing and half your...

• The Impact of Human CO2 On Atmospheric CO2 – Summary
  The simple physics model – using IPCC’s outflow proportional to level and e-times –proves natural CO2 controls atmospheric CO2. As of 2020, natural CO2 has added about 100 ppm, and human CO2 only 33 ppm, to IPCC’s CO2 level of 280 ppm in 1750.
• The Ocean Is Still Sucking Up Carbon—Maybe More Than We Think
  Recent studies looking at carbon-sequestering microbes suggest we still have a lot to learn about the ocean’s biological carbon pump.
• Will Planting Trees Reduce Global Warming?
  The mutual relationships between forests and climate are actually really rather more complex and not fully understood.
• Why is the CO₂ Concentration Rising?
  They also showed that it is very illogical to think that a slight increase in the up-flux cannot be compensated by a larger down-flux. It’s like increasing the heat energy flow in a house by 5% and expecting that the temperature will keep on rising...
• Estimates of the carbon cycle – vital to predicting climate change – are incorrect, Virginia Tech researchers show
  However, Virginia Tech researchers discovered that when using the accepted numbers for soil respiration, that number in the carbon cycling models is no longer balanced.
• CARBON CYCLE
  The increase in 12C in the atmosphere is, in my opinion, weak evidence that the annual increases are driven only by fossil fuel sources. The atmosphere can’t tell ‘anthropogenic’ carbon dioxide from natural carbon dioxide. It seems unlikely that...
• Claim: Climate and carbon cycle trends of the past 50 million years reconciled
  Predictions of future climate change require a clear and nuanced understanding of Earth's past climate. In a study published today in Science Advances, University of Hawai'i (UH) at Mānoa oceanographers fully reconciled climate and carbon cycle trends...
