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.

Four new datasets developed as part of 4C project are now available.

The Southern Ocean is the largest oceanic sink for human-made carbon dioxide. New research supported by 4C reduces the uncertainty about how much human-made carbon dioxide can be absorbed by the Southern Ocean, by 50 percent.

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.

New research supported by 4C shows 64 countries cut their fossil CO₂ emissions during 2016-2019, but the rate of reduction needs to increase tenfold to meet the Paris Agreement aims to tackle climate change.

The 4C project publishes the Carbon Outlook for 2020, which describes changes in the atmospheric concentration of CO₂, and provides an update on the state of the carbon sinks. 

The latest animated infographic developed by the 4C project explains why predicting future emissions is crucial to make the best decisions today to mitigate climate change.
