The U.S Global Change Research Program (USGCRP) has been implemented for 10 yrs, and so many achievements were carried out. The paper reviewed some main progresses which were made by USGCRP over the past decade. These achievements were made in the following fields: National Assessment, El Niño-Southern Oscillation (ENSO) forecasting, global temperature record, warmest period in at least 1000 years, north America carbon sink, greenhouse gas increase and ozone depletion, assessment of ozone depletion, long-range transport of air pollution, ocean analysis, Tropical Rainfall Measuring Mission (TRMM), Radarsat, fire monitoring, SeaWiFS, and global environmental change information service. Goals and Objectives for USGCRP in the coming decade were indicated in this paper. In the decade ahead, USGCRP will strengthen the researches on the following fields: understanding the Earth's Climate System, biology and biogeochemistry of ecosystems, composition and chemistry of the atmosphere, paleoenvironment/paleoclimate, human dimensions of global change, the global water cycle, carbon cycle science, observation/monitoring/data management.
