Carbon cycling refers to the set of biogeochemical processes that regulate the transformation, transport, and storage of carbon among major Earth system reservoirs, including the atmosphere, terrestrial biosphere, oceans, and lithosphere. It encompasses autotrophic carbon fixation, heterotrophic respiration, decomposition, sedimentation, weathering, and anthropogenic fluxes such as fossil fuel combustion and land-use change. Research on carbon cycling quantifies fluxes and pool sizes, characterizes feedbacks between carbon reservoirs and climate, and employs observational networks, isotopic tracers, and Earth system models to constrain budgets, residence times, and perturbation responses across temporal scales from diurnal to geologic.
The Amazon rainforest is of crucial importance to the Earth's ecosystem, given its capacity to store substantial amounts of carbon in its vegetation. In 2023, the region experienced unusually high temperatures, reaching 1.5°C ...
