State of the carbon cycle: An annual update of the global carbon budget

The Global Carbon Project will update annually the global carbon budget around July-August of each year when data from the various budget components is available.

Data and data sources are available from:

Fossil fuel emissions have increased exponentially for the past decades with a clear acceleration in the growth rates over the last few years. Atmospheric CO2 concentrations and global mean temperature have increased accordingly.

Current emissions are following the trajectory of the IPCC-SRES (2000) "AIB" scenario (a globalized, technologically advanced world in which energy production includes a broad portfolio of fossil-fuel and non-fossil-fuel sources). Emissions are growing much faster than required for stabilisation at either 450 or 650ppm.
