Kohlenstoffflüsse

Kohlenstoffflüsse, also known as carbon fluxes, refer to the movement of carbon atoms between different reservoirs in the Earth's system. These reservoirs include the atmosphere, oceans, land (biosphere and soils), and geological formations. The carbon cycle is a continuous process where carbon is exchanged between these reservoirs through various physical, chemical, and biological processes.

Key processes driving these fluxes include photosynthesis, respiration, decomposition, combustion, and ocean-atmosphere exchange. Photosynthesis by plants and other organisms removes carbon dioxide from the atmosphere, converting it into organic matter. Respiration by living organisms releases carbon dioxide back into the atmosphere. Decomposition of dead organic matter by microbes also releases carbon. Combustion of fossil fuels and biomass releases large amounts of carbon into the atmosphere. The oceans absorb and release significant amounts of carbon dioxide from and to the atmosphere.

Understanding carbon fluxes is crucial for comprehending climate change. Human activities, particularly the burning of fossil fuels and deforestation, have significantly altered the natural balance of carbon fluxes, leading to an increase in atmospheric carbon dioxide concentrations. This accumulation of greenhouse gases traps heat, causing global warming. Scientists monitor these fluxes to assess the impact of human activities on the climate and to develop strategies for mitigating climate change. Tracking the movement of carbon helps in estimating the net change in carbon storage within different Earth system components.
