To properly conceptualize the future

35 different emissions
scenarios — each of which the IPCC claimed
as having an equal
probability of occurrence
No judgment is offered in this report
as to the preference for any of the
scenarios and they are not assigned
probabilities of occurrence
Recall that 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
probability of occurrence.
As you point out, the IPCC does not explicitly state that the SRES scenarios all are of equal likelihood, but, given what they do tell us (as you indicated) 1) we should not rely on the frequency distribution to develop probability of occurrence, and 2) «No judgment is offered 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

Response: IPCC did not attach any
probabilities to any of the
scenarios (which I think was probably a mistake,

Similiarly, if possibility theory admits that evidence can make an event «more likely», then the requirement to be able to rank
scenario classes
as more or less likely than each other leads to something that looks a lot like
probability in the end, and the debates about whether a risk justifies action should depend on how one evaluates the evidence, and one's aversion to risk, rather than the terminology used to quantify risk (or not).
Response:
As discussed elsewhere on the site, the IPCC
scenarios do not come with
probabilities attached.
The statistics associated with
scenarios from the literature do not imply
probability of occurrence (e.g., the frequency distribution of the

Generally speaking, when a person commences a lawsuit
as a result of their injuries, whether they result from a motor vehicle accident
as in the above
scenario, or by some other means like a slip and fall, the injured person is responsible for proving, on a «balance of
