IPCC WGIII Fourth Assessment Report, Second Order Draft
A 3 1 3 10 Figure SPM.2 is confusing and difficult to interpret and will not
help policymakers get the main messages of the report.
(Steve Sawyer, Greenpeace International)
A 3 1 3 1 This figure is very hard to interpret. The caption needs to be made
much clearer.
(Paul Baer, EcoEquity)
A 3 1 0 0 figure SPM. 2: on the ordinate axis, replace "Gt CO2" by " million
kt" or "billion tons". (for the same reason as above)
(Faouzi Senhaji, I.A.V. Hassan II (GERERE))
A 3 1 0 0 Figure SPM.2: This is a very important and informative figure, but
I suspect that many non-experts will struggle to extract and
understand the information it contains. It would greatly benefit
from the attention of a skilled graphic designer working with the
relevant authors. The caption should be shorter, if possible, but
needs to provide all necessary support for the figure. The current
legend is incorrect: the figure does NOT show CO2/energy, let
alone population, itself - what the legend should say is "CO2
emissions associated with changes in ...". The figure is important
and valuable, and is likely to be used in other contexts. Its design,
legend, and caption, deserve very serious attention to make it as
clear, understandable, but also as correct as possible.
(Andy Reisinger, TSU IPCC Synthesis Report)
A 3 1 3 10 Should the vertical axis on Figure SPM.2 be annual growth rate in
%, rather than GtCO2? The appearance of population in this figure
suggests so.
(Michael Raupach, CSIRO Marine and Atmospheric Research)
A 3 1 3 10 This figure SPM 2 is not clear, and is quite misleading. Either it
should be taken out or given a greater introduction as it is in
Chapter 1.
(Catherine Pearce, Friends of the Earth International)
A 3 1 3 20 In Figure SPM3 it would be useful to explain what the %ges are of
i.e. that 46.4% is the %ge of GHG emissions. It would also be
useful to show the %ges of world population i.e. mark that Annex
