The detection and documentation of global change requires distinguishing natural from anthropogenic-induced variability, and distinguishing real variability from error. It is important to observe and document the processes that are responsible for change as well as the changes in state of the systems involvecI.

The GCDIS must not impede progress by imposing cumbersome rules, unrealistic standards for data acceptability, unwieldy cost recovery procedures, or by placing unnecessary demands on computer and network resources. Rather, the GCDIS should provide a broader organization and access capability.

. The USGCRP should establish a process for idealizing critical global change datasets am for ensuring that they are archived and distributed through the GOD S

Understanding Key Processes Working Group The second activity stream of the USGCRP is "understanding key processes through a program of focused studies to improve our knowledge of the physical, chemical, biological, geological, and social processes that influence and govern the effects of global change on natural systems" [CEES, 19921. Process studies seek to find linkages between observations through hypothesis testing.

If the latter is envisioned, a mechanism for selecting a few key global change issues and the essential datasets needed to address them should be part of the GCDIS. He GCDIS should include mechanisms for retrieving relevant global change datasets that are not currently accessible through electronic media.

From page 13... ...
The Plan should define the role of special libraries as a source for access to global change bibliographic information and as-a source for information on landmark publications. The GCD S should encourage the participation of international groups currently working on [arge-scale process studies.

The Plan should include milestones for achieving the GCDIS goals of the agencies. Predicting Global Change Working Group The third activity stream of the USGCRP is "predicting global and regional environmental change through the development and application of integrated conceptual and predictive Earth system models" [CEES, 19921.

From page 15... ...
Currently, there is no single place where a researcher can obtain ecological data on a subject relevant to global change or to even be directed to such data. Formation of an ecological data center is timely given the obvious need-for ecological data in global change research, and the establishment of the National Biological Survey and the U.S.

. The working group of the forum that reviewed He Plan in terms of meeting the needs of assessing implications of global change raised the following comments concerning the Plan: The Plan should specify how it Will facilitate the assessment actuaries outlined in the USGCRP.

They will complement the work and employ the services of those centers. Existing data resources will play essential roles in the research layer of the user pyramid, and can be linked as required to any TODA's virtual data center function to avoid duplication of effort.

From page 18... ...
TODAs will also play important roles in supporting synthesis activity higher in the user pyramid and in leading researchers who must cross disciplinary boundaries to conduct their own integrated analyses and assessments to the best sources of quality survey documentation and supporting annotated bibliographies. They must therefore be staffed, as well, by knowledgeable librarians who know the field and can direct inquiries expediently through a growing and evolving array of sources and citations.

From page 19... ...
The TWGDMGC must discourage this type of bartering and insist that the very highest levels of government work with the research community to confront the issue of access directly and to think creatively about a strategy for achieving, for example, the "full, open and prompt exchange of relevant scientific, technological, technical, socio-economic and legal information related to the climate system and climate change" called for in, among other places, the Framework Convention on Climate Change. Engaging the National Information Infrastructure Task Force might be a good place to start.
