First National Climate Asssessment
The First National Climate Assessment, entitled Climate Change Impacts on the United States: The Potential Consequences of Climate Variability and Change, was published in 2000 and was a major landmark in the ongoing effort to understand what climate change meant for America. This assessment began a national process of research, analysis, and dialogue about the coming changes in climate, their impacts, and what Americans can do to adapt to an uncertain and continuously changing climate.
