Our Changing Planet: The FY 1998 U. S. Global Change Research ProgramDIANE Publishing, 1997 - 118 pages Presents an overview of the 1998 research program which focuses on four key areas of Earth system science that are of significant scientific and practical importance: Seasonal to Interannual Climate Variability; Climate Change Over Decades to Centuries; Changes to Ozone, UV Radiation, and Atmospheric Chemistry; and Changes in Land Cover and in Terrestrial and Aquatic Ecosystems. Appendices include the proposed budget for 1998, FY96-FY98 budget by agency and program, explanatory notes, and contact information. Maps, graphs, and tables. |

Page 63 - Convention, stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.
Page 91 - The overall goal of NASA's Earth Science Enterprise (ESE) is to understand the Earth system and the effects of natural and human-induced changes on the global environment. To preserve and improve the Earth's environment for future generations, policies and decisions worldwide should have the strongest possible scientific basis. The vantage point of space provides information that is obtainable in no other way about the Earth's land, atmosphere, ice, oceans, and biota, as well as the impact of humans...
Page 45 - Data should be provided at the lowest possible cost to global change researchers in the interest of full and open access to data. This cost should, as a first principle, be no more than the marginal cost of filling a specific user request.
Page 88 - DOI also sponsors contributing research programs addressing the collection, maintenance, analysis, and interpretation of short- and long-term land, water, biological, and other geological and biological processes and resources through dispersed observing networks; research in land use and land cover, including creation of maps and digital data products; and inventorying and monitoring of biological habitats, resources, and diversity.

Page 102 - ... ecological implications of global changes and the need to maintain US leadership in this area. Since its inception, the USGCRP has been directed toward strengthening research on key scientific issues, and has fostered much improved insight into the processes and interactions of the Earth system. The results of research supported by the USGCRP play an important role in international scientific assessments, including assessments of climate change and stratospheric ozone depletion. The USGCRP research...
