I. Overview

An organizational meeting of the U.S. National Assessment Synthesis Team (NAST) took place February 8th from 4-7PM and February 9th from 8AM-5PM to introduce members and review the terms of reference for the group. The meeting was chaired by Dr. Jerry Melillo and Dr. Tony Janetos, the co-chairs of the NAST. The ten members of the NAST met as a group on the 8th and the morning of the 9th. The afternoon of the 9th, they were joined by fourteen members of the National Assessment Working Group (NAWG), which includes representatives of federal agencies involved in the assessment.

On the morning of the 9th, the Science and Technology Advisor to the President, Dr. Jack Gibbons and the Acting Associate Director for Environment, Dr. Rosina Bierbaum joined the group and discussed their expectations for the assessment. Dr. Robert Corell, Dr. Michael MacCracken and Ms. Melissa Taylor were also present for the full meeting in their capacity as staff and leadership of the United States Global Change Research Program. Dr. Donald Wilhite from the University of Nebraska attended the meeting as an observer and potential NAST member. On the 9th, a representative from the National Science Foundation legal department provided a briefing on the Federal Advisory Committee Act (FACA); the next meeting of the Synthesis Team will be the first operating under FACA guidelines.

III. Terms of Reference for the Synthesis Team

The Synthesis Team discussed the Terms of Reference, including audience, scope, specific responsibilities, and timing and format of the Synthesis Report. The following were some of the conclusions developed during this discussion:

  • There are multiple audiences for the assessment, but Congress is the principal audience for the Synthesis Report.
  • The responsibilities of the Synthesis Team include writing the Synthesis Report, identifying sectors and some oversight of the sectoral analyses, thinking through a template, and providing guidance on scenarios.
  • The regions will provide primary inputs for the Synthesis Report, although the agencies have a strong interest in catalyzing and overseeing the regional efforts in conjunction with the National Assessment Coordination Office (NACO).
  • The Synthesis Report is envisioned as a "relatively brief" document, which will have more lengthy underlying documentation; it needs to be finished and reviewed before December 1999 so that it can be presented by January 2000.

IV. Climate Scenarios

With respect to climate scenarios, the Synthesis Team determined that it would be most useful to provide the teams with a suite of tools that are consistent, ranging from qualitative to quantitative products. Within this suite, they determined that there was a need for providing some General Circulation Model scenarios, but that it was vital that these were transient runs, and that we must use this assessment to move away from the focus on 2xCO2 (equilibrium) scenarios.

The Synthesis Team ultimately decided upon three products:

  • A Historical Climatology of the U.S.
    This has been compiled by NCAR and NOAA for the years 1895-1993. The monthly version is available now, and the daily version will be available soon. They are currently working on Hawaii and Alaska.

  • Two General Circulation Model Simulations
    The only transient runs that we know are currently available, and that provide the data on the variables of interest to consequence studies are the Hadley (UK Met Office) runs. Hadley has runs with and without aerosols out to 2100, with increasing concentrations of 1% per year. This is accompanied by a baseline and a 500 year natural variability run.

    However, there is interest in also finding a U.S. model or models that can be used; to some degree this was seen as a problem of computer time and resources.

  • "What If" Scenarios
    It was determined that there is also a need to provide selective, qualitative variance with a series of "what if" scenarios that each region or sector could develop. One technique would be to apply historical events to the future. Another would be to determine the sensitivity of the system, by examining the tolerance ranges (asking where a particular sector or system would get into trouble).

The Synthesis Team concluded with the following action items:

  • A Subgroup was formed (Eric Barron: team leader, Tom Karl, Dave Schimel, Don Wilhite) which will draft a 3 page paper over the next two weeks addressing "What will be available by this summer?". This will describe the content of the historical climatology, the possibilities of using GCM runs in addition to Hadley, and will develop a narrative about the "what if" component. The Subgroup will work closely with Dick Ball (Department of Energy) and his Scenario Task Force.

V. Socioeconomic Scenarios

In addition to the climate scenarios, the Synthesis Team discussed the need to provide some socioeconomic scenarios to the regions and the sectors. The Team recognized the higher uncertainties involved with doing socioeconomic scenarios. There was interest in providing a framework to enable the sectoral teams to do sensitivity analyses, looking at parametric ranges within sectors.

The Synthesis Team ultimately decided to attempt to develop a scheme that combined measures of broad system resilience/demand/activity (High/Low) with measures of aggregate economic activity (Weak/Robust). It was determined that the former applied to the sector and the latter to the region:

Broad System Resilience / Demand / Activity
(Applies to Sector)
Aggregate Economic Activity
(Applies to Region)
High Weak
Low Robust

It was suggested that you ask the regions to select 2-3 sectors and then address the following question:

  • What would get them into trouble?

However, it was determined necessary to give some guidance about what these subjective terms meant, and to give guidance on "plausibility" since some combinations might not be feasible.

The Synthesis Team concluded with the following action items:

  • A Subgroup was formed (Granger Morgan: team leader, Ted Parson, Barbara Miller, Rich Richels, Linda Joyce) which will develop some guidance over the next two weeks about how to use this approach. It was determined that this Subgroup would use specific sectors as illustrations.

VI. Sectors

The Synthesis Team began by discussing the criteria that might guide the selection of sectors, including high social multiplier effects, sectors where the ability to do an assessment is mature, areas that would be risky, most vulnerable systems, and areas with constituencies.

After listing candidate sectors, the Synthesis Team developed a list which enabled integration of key issues and topics:

  • Forests (managed, unmanaged, recreation, biodiversity)
  • Coasts (communities/built structures, recreation, wetlands, fisheries, beach erosion, biodiversity)
  • Agriculture (agrobusiness, family-scale farming, grasslands and grazing, international aspects, biodiversity)
  • Water (imports/exports, mining, tourism, biodiversity), and
  • Health (laying out a research agenda; explorative).

The Synthesis Team developed the following action items:

  • Over the next two weeks, the Co-Chairs of the Synthesis Team will develop a liaison scheme to provide a role (or roles) for the Synthesis Team in the sectoral assessments. As next steps, they will work with the Synthesis Team in identifying leads for each sector, putting together teams, and developing a Terms of Reference for the sectoral assessments.

VII. Regions

The primary input on the regional assessments was provided by the National Assessment Working Group, which has been catalyzing (and funding) the regional activities over the past year. The Synthesis Team agreed with the recommendation of the National Assessment Working Group to preserve the existing workshop regions for this first phase of the assessment (the next 23 months), to establish a Regional Council, and to aim for a competitive process over the longer term, beyond January 1, 2000.

However, the Synthesis Team agreed that there should be an effort to work towards mechanisms (even at this stage) to encourage collaboration at a "mega-region" scale. It was suggested that the "product" from the regions for the Synthesis Team would hopefully be synthesisized analyses at the mega-regional scale, based on an integration of reports from all regions.

The Synthesis Team recognized that the regional activities would be a principal source of material for the Synthesis Report; however, the interactions between the regions and the Synthesis Team could not be fleshed out until both the agencies and the regional leaders were able to further develop the strategy for how these activities and assessments would proceed. The Synthesis Team deferred to the agencies and regional leaders to further develop the strategy for the regions (based on their understanding that this was the strong interest of these groups to lead these efforts).

  • As an action item, it was determined that the National Assessment Working Group would implement the agreement to preserve the existing workshop regions, facilitate the establishment of a Regional Council, and further develop the strategy for the regional activities. This strategy should clarify how the agencies and the regions see the interactions with the Synthesis Team, and should discuss expectations for how the regional contributions should be reflected in the Synthesis Report.

VIII. Templates

The Synthesis Team discussed templates for the assessments along with the National Assessment Working Group. Some of the conclusions of the discussions were that (a) there should be a focus on visuals; (b) maps should be used as much as possible; (c) do not over-generalize, but use stories and case studies; and (d) develop key indicators, not in scientific language, but in terms that people understand.

  • As an action item, it was determined that the Synthesis Team should provide input to the National Assessment Working Group about the handouts in the packet.

IX. OSTP Participation

Dr. John Gibbons (Director, Office of Science and Technology Policy) and Dr. Rosina Bierbaum (Acting Associate Director, Office of Science and Technology Policy) participated in the first hour of the second day of the meeting.

Dr. Gibbons noted the importance of the regional workshops in entraining stakeholders, gathering regional information, and raising public awareness of the issue. He characterized the regional activities as the disaggregated looks at the nation and noted the need for the Synthesis Report as a national perspective for Congress.

In addition to the questions that were listed in his letter to Dr. Corell, he added some additional questions dealing with levels of concentrations, rates of change, and international couplings:

  • How bad is it if we get to 550 ppmv? What is the impact on the nation and the world?
  • How fast do we need to respond? What is the trigger point?
  • What are the international couplings and interactions that we need to be looking at?

In terms of audience, he suggested that the group look at Congress as the surrogate for the American people. He noted that the regional work will be a very important input for the national Synthesis Report.

Dr. Bierbaum reiterated the importance of examining non-linearities, involving partners, and focusing on the education and communication aspects.She also stressed the importance of leaving adequate time for synthesis, integration, and the development of key visuals.
