Question

Background and the environment immediate and far

Answer 1

Answer:

During its first 10 years of operation, the U.S. Global Change Research Program (USGCRP) has advanced our understanding of the Earth's ever-changing physical, chemical, and biological systems and the growing human influences on these systems. On the basis of this knowledge we can now focus attention on the critical unanswered scientific questions that must be resolved to fully understand and usefully predict global change. Such capability is increasingly important for developing our economy, protecting our environment, safeguarding our health, and negotiating international agreements to ensure the sustainable development of the United States and the global community of nations. There are now compelling reasons for scientific knowledge to guide and respond to policy options, both current and future. Clearly, we must delineate research pathways that will enlarge our understanding of changes in the global environment, including climate change. At the same time we need to reduce uncertainties in the projections that shape our decisions for the future. For all these reasons it is essential that the USGCRP continue to receive strong financial support and continue to provide continuing strong scientific leadership. To be effective the USGCRP must be based on a sound scientific strategy, focused on key unanswered scientific questions, using a correspondingly balanced strategy for supporting observational, data management, and analysis activities.

On the basis of the continuing reviews of the Committee on Global Change Research (CGCR) and those of its collaborating bodies, the committee reaffirms the achievements and significance of the USGCRP while finding that the Program must now be revitalized, focusing its use of funds more effectively on the
