*These are used to determine how the CDR data is grouped and displayed
Calculating the amount of CO2 that will need to be removed from the atmosphere in 2100 for a specific temperature increase is fraught with uncertainty but is essential to crafting the response to global warming. A simple model, based on the data from the IPCC’s 1.5°C report, was developed to allow people to explore the CO2 removal requirement for a variety of possible values for the major climate variables – equilibrium climate sensitivity, temperature increase in 2100, cumulative emissions from 2020 through 2100, and non-CO2 radiative forcing in 2100.

for a description of the model and the various climate variables.
You can run the model to estimate the CDR requirement for a variety of values for the climate variables by selecting different values in the drop-down lists to the left and clicking the "Submit" button above.
