To involve experts beyond the writing teams, discuss issues which to date received insufficient attention to address current policy questions properly, and to allow for interaction with the writing teams of the other two Working Groups, Working Group III sponsors various Expert Meetings and Workshops including:
IPCC Expert Meeting on Geoengineering
Lima, Peru, 20-22 June 2011
The joint IPCC Expert Meeting of the Working Groups I, II and III provided a platform for exchange and discussion on geoengineering among experts from different disciplines as a cross-cutting issue of the Working Groups' contributions to the Fifth Assessment report.
IPCC Expert Meeting on Economic Analysis, Costing Methods, and Ethics
Lima, Peru, 23-25 June 2011
The joint IPCC Expert Meeting of the Working Groups II and III addressed issues of representing climate impacts in monetary and non-monetary terms, aggregating benefits and costs and implications for cost-benefit analysis (CBA) and the ethical dimensions of estimating costs of mitigation, adaptation and residual damages.
Preparation of this Guidance Note was an agreed outcome of the IPCC Cross-Working Group Meeting on Consistent Treatment of Uncertainties, which was held in Jasper Ridge, California, USA, from 6-7 July 2010.
Annex B: Addressing the InterAcademy Council Recommendations
1-3 November, IPCC Workshop on Socio-Economic Scenarios
This report summarizes discussions that took place and were initiated during the IPCC Workshop on Socioeconomic Scenarios for Climate ChangeImpact and Response Assessment (WoSES) in Berlin, Germany, 1-3 November,2010. The scientific core of this workshop report briefly sketches theoutcomes and conclusions of WoSES. It contains a standalone paper (Annex I) initiated during the workshop that was widely circulated to the relevant scientific communities for feedback and will be submitted forpublication in a peer-reviewed journal in the coming months. This framework paper will serve as a reference document for the integratedassessment modelling, impacts, and adaptation communities in theirongoing research feeding into the AR5, particularly of Working Groups II and III. This workshop report also includes the Workshop Programme andthe Participant List.
This meeting aims to (a) provide desirable and feasible characteristics of emissions and stabilisation scenarios, (b) information exchange on plans for developing scenarios and coordinating activities among the scientific community, and (c) the enhancement of developing country/economies in transition involvement in scenario development.
The Task Group on New Emission Scenarios (TGNES) has prepared a report on “Recommendations on New Emission Scenarios", with a view to enable the IPCC Panel to take decisions on the role of the IPCC, and deliverables, timelines and organizational arrangements for the development and assessment of new greenhouse gas emission scenarios, in advance of a possible IPCC Fifth Assessment Report.
This meeting dealt with the following issues:
- Baseline emission scenarios: assessment of new literature since SRES.
- Mitigation and stabilization scenarios and strategies, and costs and socio-economic implications
- Development pathways, trends and goals.
- Role of technologies in long-term mitigation and stabilization
- Interaction of mitigation and adaptation, in the light of climate change impacts and decision making under long-term uncertainties.
- Linkages between short and medium term mitigation and long-term stabilization
16-18 February: Expert meeting on Integration of Adaptation and Mitigation and Sustainable Development, Reunion Island, France
The deliverables of this meeting were:
- To feed new views from outside the climate change literature into the assessment of WG II and WG III concerning the strongly interrelated area of adaptation, mitigation and sustainable development.
- To dove-tail zero-order draft texts of WG II and WG III (by the authors) with a view to ensuring that the treatment of AM – SD issues in both assessments is: “Consistent, Complementary, Concise and Complete” (“4 Cs”).
- Evaluating user needs and requirements.
- Identifying what kind of scenarios could meet these user needs and requirements.
- Discussing options for the role of IPCC with regard to development of new scenarios
The goal of this expert meeting was:
- To identify key drivers on industrial technology development, transfer, deployment and diffusion to be addressed in the AR4
- To contribute to building the conceptual framework for the assessment
- To gain access to industrial information networks being relevant for the scientific assessment of climate change mitigation and improve the use of publicly available data sources from industry in the AR4
21–23 July 2003, Geneva, Switzerland: IPCC Expert Meeting on Current Scientific Understanding of the Processes Affecting Terrestrial Carbon Stocks and Human Influences upon them.
The goal of this expert meeting was to survey the scientific understanding of carbon cycle processes.
5-7 March 2003, Colombo, Sri Lanka: Expert Meeting on Integrating Sustainable Development and Climate Change in the IPCC Fourth Assessment Report.
This meeting was organized to make a start to ensure the incorporation of sustainable development in the AR4 in a integrated way, between all WG II and III AR4 chapters.
19-21 November, Regina, Canada: IPCC Workshop on CO2 Capture and Storage (CCS).
The Workshop assessed the state of knowledge and the prospects to deliver sufficient scientific and technical information for a Special Report on CCS.
