CO2 buildup

CO₂ buildup occurs when the amount of carbon dioxide in the atmosphere increases faster than natural processes can remove it. This often results from human activities like burning fossil fuels, deforestation, and industrial processes, which release large quantities of CO₂. As CO₂ accumulates, it traps more heat in the atmosphere—a phenomenon known as the greenhouse effect—leading to global warming. Elevated CO₂ levels can also impact ecosystems, weather patterns, and ocean chemistry, contributing to climate change and environmental shifts worldwide.
