Advice needed: Discussion about past and future IPCC

On 16 November I have been invited to participate at a panel discussion about the past and future IPCC. The panelists have been asked for an initial statement. So far I am thinking of concluding my statement with this:

" IPCC is an indispensable effort.
 • IPCC processes need to be improved.
- Mechanism
to deal with claims about errors and conflicts of interest.
- Consideration that “payment” may take the form of societal or professional recognition, not only in terms of money
- Documentation and highlighting of contested areas and areas of significant lack of scientific analysis
- Mechanisms to prevent formation of networks of lead authors.
- Factoring into the assessment that scientifically constructed knowledge may be conditioned by culturally constructed (value-based) knowledge claims.
 • Decentralized “regionalization” efforts (aka BACC etc.) where suitable."
 I wonder if some Klimazwiebel-readers may have some constructive comments.

Bojanowski - konkretisiert seine Vorbehalte

Vor einiger Zeit (2. November 2014) machte Axel Bokanowski mit seinem Artikel Alarm geht vor Genauigkeit im SPIEGEL Furore, was unter manchen meiner Kollegen deutlichen Widerspruch auslöste und das Verlangen, mit Zitaten und Quellen die Vorwürfe zu substantiieren. Dies ist nun geschehen auf der Webseite: http://axelbojanowski.de/ipccsynthesisreport
Bojanowksi sagt dazu "Sehe den Synthesis-Report weiterhin sehr kritisch".

Deutsche Zusammenfassung von IPCC WG 3

Am Sonntag, 18. Mai 2014 in der WELT am Sonntag Vorwürfe über eine Informationsbroschüre von Bundeseinrichtungen zum Thema IPCC (Nachtrag 4. Juni 2013 - http://www.welt.de/wirtschaft/article128124861/Die-dreiste-Berichtsfaelschung-der-Klimatrickser.html";vollständige Fassung). Da es immer gut ist, Betroffene mit O-Ton zu lesen, habe ich Christiane Textor von der Deutsche IPCC-Koordinierungsstelle und Harry Lehmann vom UBA angeschrieben mit ein paar Fragen. Nach etwa 14 Tagen gab es von Christiane Textor diese (vermutlich abgestimmten) Antworten:

The future of the IPCC

There is lots of talk how the IPCC could be continued or modified. I want to add one more scenario, namely regionalization.

Immerhin äusserte sich das IPCC hier explizit zuu Vorwürfen.

Richard Tol on Working Group 3 of IPCC

Guest posting by Richard Tol

The Fourth Assessment Report (AR4) of Working Group II (WG2) of the Intergovernmental Panel on Climate Change (IPCC) has been discussed extensively in recent months. A number of errors were discovered. Few documents are without fault. What is surprising, however, is that the IPCC has denied obvious mistakes; and that the errors all point towards alarmism about the impacts of climate change.

The WG3 report did not attract the same scrutiny. This could create the impression that WG3 wrote a sound report. That impression would be false. Just as WG2 appears to have systematically overstated the negative impacts of climate change, WG3 appears to have systematically understated the negative impacts of greenhouse gas emission reduction.
