The primary function of carbon sinks in regulating climate is to absorb and store atmospheric carbon dioxide (CO2), helping to mitigate the effects of climate change. Key carbon sinks include forests, oceans, and soils, which sequester carbon through processes like photosynthesis and organic matter accumulation. By keeping CO2 levels in check, carbon sinks play a critical role in maintaining global temperatures and climate stability. Their degradation due to deforestation, land-use change, and pollution releases stored carbon back into the atmosphere, exacerbating climate change. Therefore, protecting and restoring carbon sinks is essential for effective climate change mitigation strategies.
