IPCC WGIII Fourth Assessment Report, Second Order Draft
change damages and other co-benefits is a laudable goal, such a
comparison is complicated by inherent uncertainties in predicting
benefits and the methods of relating longer-term benefits to nearerterm
costs.” Clarify text U.S. Government
(Government of U.S. Department of State)
8 A 8 17 0 0 That something is very complex is not a very informative
assessment. Can't a more daring statement be made? E.g., that the
number, size, varied nature and sometimes subjective (e.g. discount
rate) character of the uncertainties in determining costs and benefits
make a quantitative comparison not meaningful? This was basically
the SAR conclusion. Such a statement would not deny the
usefulness of a more qualitative CBA. The current formulation may
suggest that as we do more research, uncertainties would be
reduced and a meaningful quantitative CBA becomes possible. A
more modest change would be to add " and involves many
subjective assumptions" right after "complex".

8 A 8 17 8 17 Insert reference to section [3.5] at end of first sentence. If any one
sentence in the report is to be considered unambigously true, this is
it. However, the reference should be to the section where this is
most comprehensively discussed which is section 3.5. This
reference will then show in bold.
