FUND and PAGE express the thermal inertia of the system in terms of an e-folding time (third line of the table), while DICE uses heat capacities (although the parameters are not presented this way, see fifth and sixth lines of the table and online supplement for details).
In FUND, the modal value of the e-folding time of global warming is 44 yr ([phi][DELTA]t = 44 yr), while PAGE assumes the most likely value is 30 yr (FRT = 30 yr).
The climate sensitivity and e-folding time are not chosen independently in the ensemble models FUND and PAGE.
