Mechanisms of Anthropogenic Emissions and Climate Change Impacts on the Oceanic and Terrestrial Carbon Cycles

Anthropogenic emissions, as well as the ever-growing rate of climate change, enter into a global carbon cycle, which lies at the core of the climatic regulation of the planet. Although terrestrial and oceanic systems have in the past played a key carbon sink role, current evidence indicates that the ability of these systems to absorb carbon is being nullified by a complicated mixture of human interference combined with climate change-related feedback processes. It has been noted, in this paper, that the underlying mechanisms between anthropogenic emissions and climate change leading to modification of the carbon cycle on land and oceanic platforms have been investigated. The research assesses the processes that cause change in carbon uptake, storage and release, in a critical way that reflects on the new and recent advances in the study of Earth system modeling, satellite remote sensing, and observational studies. According to the analysis, the signs of stability weakening appear on both oceanic and terrestrial carbon sinks, and the risks of tipping points leading to the degradation of such sinks to sources are growing. The results highlight the seriously threatened state of the carbon cycle worldwide that necessitates better surveillance, flexible government, and policy action to protect the global carbon cycle integrity during temporary environmental variation.
