Record Label : 1pctCO2to4x-withism
Record Title : simulation with interactive ice sheet forced by 1 percent per year increase in CO2 to 4xCO2 (subsequently held fixed)
Record identifier : f16e76a6-dd9e-11e6-b89b-ac72891c3257
Description : Increase atmospheric carbon dioxide by 1% per year to quadrupling then hold fixed for 200 years in a model with interactive ice sheets. The experiment should be identical to the corresponding standard CMIP AOGCM experiment except for the treatment of ice sheets. 1pctCO2to4x-withism forcing differs from the 1% increase in CO2 experiment in that after year 140 , when the CO2 levels = 4xCO2, the concentration of CO2 remains set to 4xCO2 for the remainder of the experiment Run for a minimum of 350 years (500 years encouraged).
