Currently, humans are emitting over 29 billion tonnes of carbon dioxide into the atmosphere per year. What remains in the atmosphere is called the ‘airborne fraction’. The rest is absorbed by vegetation and the oceans. One indisputable fact is clear, the total amount of CO2 in the atmosphere is increasing dramatically. Current CO2 levels are the highest in 15 million years.
