IPCC WGIII Fourth Assessment Report, Second Order Draft

the huge cost effectiveness and potential for CO2 mitigation that
lays in the building sector. Not enough emphasis is placed on the
issue for the time being
(Philippine de T'Serclaes, International Energy Agency)
Overall I think the SPM reads very well and has the right content.
(Rachel Warren, University of East Anglia)
SPM-58 0 A 0 0 0 0 This Summary for Policy Makers is generally very well compiled.
It is readabale, understandable, well balanced and authoritative.
My comments are relatively minor.
(James Curran, Scottish Environmental Protection Agency)
SPM-59 0 A 0 0 0 0 The SPM as it stands could, in the UK's view, convey more about
the need for action over the next decade. Estimates of costs of
delaying mitgation action have not been given. Including some of
key headings in both the SPM and the TS will help emphasise key
findings including the message that recent work is confirming
earlier impacts and revealing new important impacts.
(Government of UK)
SPM-60 0 A 0 0 0 0 Language and structure are too complex to be accessible to policymakers
and the style is sometimes uneven– simple structure and
more plain language would help pull out the key messages. More
explanation is required in some places.
(Government of UK)
SPM-61 0 A 0 0 0 0 It is not immediately apparent in the SPM (or for that matter the
TS) what is new and important since the publication of TAR. It
would be helpful to start the SPM by saying that the TAR of 2001
IPCC painted a picture of what we knew with a range of certainty -
repeat the 4-5 key points from TAR. Then summarise what we have
learnt since TAR - ie those parts of the story in whjch we have
greater confidence, and those parts where we need more reserarch,
any new significant points whch have emerged in AR4, and lastly
the relationship to the work of other Working Groups; - eg is there
any view on, for example, the relationship dangerous climate
change and tipping points? Does the AR4, generally speaking,
confirm the trends seen in TAR. There seems to be very little
