IPCC WGIII Fourth Assessment Report, Second Order Draft
289 regions is presented as having no implications. While it may not
affect global GDP or emissions much, it might well affect other
drivers of baseline scenarios, such as equity of distribution and
degree of regionalisation. Perhaps there is a way to rephrase this
sentence to not give the impression that Africa, Latin America and
the Middle East do not matter.

(Harald Winkler, University of Cape Town)
3 A 4 10 4 10 consider inserting "overall" before "emission levels" to differentiate
partial drivers from resulting overall emissions.
(Andy Reisinger, TSU IPCC Synthesis Report)
3 A 4 10 4 10 Suggest add example of a driver that has increased to compensate
for the lower population projections
(Rachel Warren, University of East Anglia)
3 A 4 10 4 12 "Economic growth for …" Is this a key message to be reported in
the SPM (including pre-TAR/TAR/post-TAR jargon)? (too
defensive, don't try to satisfy the IPCC criticasters in the SPM)
(Government of European Community / European Commission)
3 A 4 11 0 0 TAR should be spelled out the first time TAR is used.
(Government of Norwegian Pollution Control Authority)
3 A 4 13 4 13 insert "Aerosols globally have a significant nett cooling effect
compared to the warming by emitted GHGs"
(Government of The Netherlands)
3 A 4 13 4 14 Penultimate sentence is confusing - does it mean the range between
the upper bound and the lower bound have narrowed; or does it
mean that for all/most scenarios these emissions are lower.
(Government of Australia)
SPM-50 3 B 4 13 4 13 … precursor …: Please explain: do you mean aerosol precursors ?
(a footnote would help in any case to explain "precursor". But
precursor is also used for NOx and COV, precursors for O3, and I
am not sure these emissions are also decreasing, as SOx does.
(Jean-Pascal van YPERSELE, Université catholique de Louvain
(Belgium))
SPM-51 3 B 4 13 4 15 Sentence does not seem to connect well with the ones before it.
