The National Assessment on Climate Change (NACC) was a massive multidisciplinary effort to study and portray in regional detail the potential effects of human-induced global warming on the United States. The project was articulated into some 20 regional studies - each involving dozens of scientific and academic experts as well as representatives of industry and environmental groups. The final reports synthesizing regional and national findings were published in November 2000, titled "National Assessment of the Potential Consequences of Climate Variability and Change." [1]
