"Over the past several years, our understanding of global environmental change and our ability to estimate its future effects has improved significantly. In order to summarize the key conclusions of this research, the U.S. Climate Change Science Program (CCSP) has undertaken a national scale \"Scientific Assessment of the Effects of Global Change on the United States.\" The conclusions in this assessment build on the vast body of observations, modeling, decision-support, and other types of activities conducted under the auspices of CCSP. It draws on findings from previous assessments of the science, including reports and products by the Intergovernmental Panel on Climate Change, (IPCC), CCSP, and others. Together with CCSP's 21 Synthesis and Assessment Products, this is arguably the most comprehensive assessment to date of the effects of global change, and especially the climate, on the United States."@en . . . . . . .
