in their 2001 Third Assessment Report, the IPCC gives a range of temperature increase between 1990 and 2100 of 1.4 and 5.8 ºC based upon the simulated output from 7 different climate models run under 35 different emissions
scenarios — each of which the IPCC claimed as having an equal

in this report as to the preference for any of the
scenarios and they are not assigned
probabilities of occurrence,» it seem to me that the best we can do is to make the simple assumption that they are equally likely (with departures from equal
probability randomly distributed).
