Scientific models and geological records indicate that anthropogenic carbon dioxide persists in the atmosphere for hundreds of thousands of years, governed by a complex sequence of biological and geological removal processes. Initial uptake occurs via the terrestrial biosphere and oceanic biological pumps, which transport carbon to the deep sea through organic matter and skeletal remains. Over much longer periods, silicate and carbonate weathering act as a natural thermostat, though new research suggests this system can overshoot, potentially triggering extreme cooling or even a future ice age. This cooling feedback is driven by nutrient runoff and plankton blooms that sequester massive amounts of carbon when ocean oxygen levels are low. While these natural mechanisms will eventually lower global temperatures, experts warn that such long-term stabilization occurs far too slowly to mitigate the immediate impacts of modern climate change. Critics and skeptics, however, remain divided on the reliability of these predictive models and the historical consistency of climate consensus.
