Annual report of the U.S. Global Change Research Program documenting activities and progress, goals for the upcoming year, proposed budget considerations, and other information about the organization for fiscal year 2002.

This Fiscal Year 2007 edition of Our Changing Planet describes a wide range of new and emerging observational capabilities which, combined with the Climate Change Science Program’s analytical work, lead to advances in understanding the underlying processes responsible for climate variability and change. The report highlights progress in exploring the uses and limitations of evolving knowledge to manage risks and opportunities related to climate variability, and documents activities to promote cooperation between the U.S. scientific community and its worldwide counterparts.

Annual report of the U.S. Climate Change Science Program documenting activities and research, goals for the upcoming year, proposed budget considerations, and other information about the organization for fiscal year 2004 and 2005.

This document, which is produced annually, describes the activities and plans of the U.S. Global Change Research Program (USGCRP), which was established in 1989 and authorized by Congress in the Global Change Research Act of 1990. Strong bipartisan support for this inter-agency program has resulted in more than a decade's worth of scientific accomplishment. "Because there is considerable uncertainty in current understanding of how the climate system varies naturally and reacts to emissions of greenhouse gases and aerosols, current estimates of the magnitude of future warming should be regarded as tentative and subject to future adjustments (either upward or downward). Reducing the wide range of uncertainty inherent in current model predictions of global climate change will require major advances in understanding and modeling of both (1) the factors that determine atmospheric concentrations of greenhouse gases and aerosols, and (2) the so-called 'feedbacks' that determine the sensitivity of the climate system to a prescribed increase in greenhouse gases. There is also a pressing need for a global system designed for monitoring climate. Climate projections will always be far from perfect. Confidence limits and probabilistic information, with their basis, should always be considered as an integral part of the information that climate …
