The increase in CO2-induced global warming will only stop when humans stop adding CO2 to the atmosphere, according to a recent report published by the 4C project. The report discusses the latest science on zero CO2 emissions, and touches on the importance of zero vs. net-zero emissions for policymaking.

The global carbon cycle involves complex processes and interactions within the Earth system, and understanding these is crucial for climate change mitigation and adaptation. This classroom explains the most important aspects of the carbon cycle and how it is affected by changes in CO2 concentrations.
