Human contributions to atmospheric CO2 are often cited as a small percentage of total CO2 emissions, but the 3% figure needs context. Here's a concise breakdown: Total CO2 Emissions : The Earth's carbon cycle involves natural sources (e.g., volcanic activity, respiration, ocean release) and anthropogenic (human-related) sources. Natural sources emit roughly 750-800 billion tons of CO2 annually, while human activities (fossil fuel burning, deforestation, industry) contribute about 30-40 billion tons per year. Human Contribution : This makes human emissions roughly 3-5% of total CO2 emissions. The 3% figure likely comes from comparing anthropogenic emissions to the total carbon cycle flux. Key Context : ...
