PLEASE NOTE: THE IPCC HAS EXTENDED ITS DEADLINE FOR SUBMITTING AR6 SCOPING MEETING NOMINATIONS UNTIL 14 NOVEMBER 2016; AS SUCH, THE U.S. GLOBAL CHANGE RESEARCH PROGRAM—ON BEHALF OF THE U.S. DEPARTMENT OF STATE—HAS ADJUSTED ITS INTERNAL DEADLINE. U.S. NOMINATIONS WILL NOW BE ACCEPTED UNTIL WEDNESDAY, 9 NOVEMBER 2016.

The U.S. Department of State seeks nominations for U.S. scientists with requisite expertise to contribute to the scoping of the IPCC Sixth Assessment Report (AR6). The AR6 Scoping Meeting will be held 1–5 May 2017, at a venue to be determined.

Background information and the nominations vehicle can be found at USGCRP's Public Contribution System. To help frame the three Working Group contributions to the AR6 and address cross-cutting themes informing development of the AR6 Synthesis Report, certain areas of disciplinary expertise are being sought. This information is appended below.

This is an Open Call. All registered users can nominate U.S. citizens and permanent lawful residents to be considered by the IPCC Science Steering Committee (SSC) overseeing selection of experts. The USGCRP nominations system for this process will be disabled on after the revised deadline, Wednesday, 9 November 2016, and a nominations package will be transmitted on behalf of the U.S. IPCC Focal Point on 14 November 2016 (revised). The SSC will complete its work and issue invitations to the AR6 Scoping Meeting (1–5 May 2017 • venue TBD) in February 2017.

AREAS OF EXPERTISE

Working Group I 

• Climate system (atmosphere, ocean, land surface, cryosphere): observations (past and present), processes, and interactions
• Natural and anthropogenic drivers of climate change (land use, well-mixed greenhouse gases, short-lived forcers including aerosols), carbon and other biogeochemical cycles
• Climate modelling, model evaluation, predictions, scenarios and projections, detection and attribution, on global and regional scales
• Earth system feedbacks and dynamical responses, including abrupt change
• Climate variability, climate phenomena and teleconnections, extremes and implications for regional climate

Working Group II 

• Impacts on and vulnerability of natural and managed systems (land, freshwater and oceans) including genetics, physiology and regional ecosystem expertise
• Palaeo and historical views of natural, managed and human systems across regions
• Impacts, vulnerability and risks for sectors including fisheries, agriculture, tourism, transport, resource extraction, energy
• Impacts, vulnerability and risks for human systems including health and wellbeing, indigenous and cultural, livelihoods, poverty
• Impacts, vulnerability and risks for settlements, including rural, urban, cities, and those on small islands and in coastal areas, and related systems and processes including food, economic and energy security, migration
• Adaptation needs, options, opportunities, constraints and influencing factors including contributions from psychology, sociology, and anthropology
• Approaches for adaptation to climate change: ecosystem and community-based adaptation, disaster risk reduction, and early warning systems
• Socio-cultural, anthropological and psychological background of making and implementing decisions

Working Group III 

• Socio-economic scenarios, modelling and transitions at the global, regional, national and local scales including integrated assessment approaches
• Energy systems including supply and energy demand sectors (e.g., industry, transport, buildings)
• Mitigation responses in agriculture, forestry, land use and waste
• Consumption patterns, human behavior and greenhouse gas emissions, including economic, psychological, sociological and cultural aspects
• Policies, agreements and instruments at the international, national and subnational levels, including those at the city level
• Technology innovation, transfer and deployment
• Financial aspects of response options

Cross-Cutting

• Co-benefits, risks and co-costs of mitigation and adaptation, including interactions and trade-offs, technological and financial challenges and options
• Ethics and equity: climate change, sustainable development, gender, poverty eradication, livelihoods, and food security
• Perception of risks and benefits of climate change, adaptation and mitigation options, and societal responses, including psychological and sociological aspects
• Climate engineering, greenhouse gas removal, and associated feedbacks and impacts
• Regional and sectoral climate information
• Epistemology and different forms of climate-related knowledge and data, including indigenous and practice-based knowledge
