# change contiously
# - EXP 27 the incoming solar rediation is increased
# - EXP 30-32 are paleo experiment with boundary conditions 231 kyr before present
# - EXP 35-37 are experiments with changed orbital parameters
# - EXP 40-47 are experiments where CO2 is doubled in parts of the globe or seasons
# - EXP 95-99 are IPCC scenarios, where the CO2 data is available
# for the years given in brackets from 1950 onward
# - EXP 100: you can run the model with your own CO2 forcing,
# which should be in the format [year co2] like for the IPCC scenarios
