IPCC WGIII Fourth Assessment Report, Second Order Draft
assess options for mitigating climate change" but the SPM does not
give the reader a sense of the options, their feasibility or the barriers
to implementation.
(Government of Environment Canada)
SPM-84 30 A 0 0 0 0 add "the private sector needs long term perspectives, in terms of
prices and policy instruments, to become fully enganged in
combatting climate change."
(Government of The Netherlands)
SPM-85 0 A 0 0 0 0 Also a more illustrative overall view about the mitigation situation
should be given to the policy makers (Ch Summary for Policy
Makers). (Technical Summary includes that material, but is rather
long for policy makers.)
(Government of Finland)
SPM-86 5 A 0 0 0 0 Summary for Policy Makers should include a picture about the
need to decrease emissions to reach the long term objectives (450
or 550 ppm CO2-eq.). The short term objectives might give a rather
optimistic view about the needed actions. Especially because
emissions might increase in the short term. Figure SPM.4 has been
given, but it is not the most basic and illustrative. (Numbers of this
Figure have been mentioned to be indicative because they are just
from two models in Technical Summary p.20 lines 10-11) Also
units for cumulative emissions (GtC) might cause
misunderstandings, when mostly units for CO2 have been used
(Government of Finland)
SPM-87 0 A 0 0 0 0 The SPM should include information on the characterisation of
uncertainty in the WG3 report. In the WG2 report an Appendix to
the SPM contained information on uncertainty and likelihood as it
related to the IPCC standard terms. WG3 should consider using a
similar mechanism.
(Government of Australia)
SPM-88 0 A 0 0 0 0 The SPM is the only part of the WG3 report that will be read by
many people. However, currently it is too technical for many policy
makers and assumes too much knowledge. It is also disjointed and
the main messages are not highlighted appropriately.
