National Assessment on Climate Change
Encyclopedia
The National Climate Assessment (NCA) is a large-scale national project that is conducted under the auspices of the Global Change Research Act of 1990, and is one of the many activities of the US Global Change Research Program (USGCRP), a program which coordinates and integrates federal research on changes in the global environment and their implications for society. The next National Climate Assessment is due to produce a report for the President and Congress in 2013.

History

The first National Assessment on Climate Change (NACC) was a multidisciplinary effort to study and portray in regional detail the potential effects of human-induced global warming
Global warming
Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its projected continuation. In the last 100 years, Earth's average surface temperature increased by about with about two thirds of the increase occurring over just the last three decades...

. 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."

Criticism

The National Assessment received criticism from many of those who were involved in its early review.
"Critics claimed that many of the model-projected impacts of possible future climate changes were overstated and unsubstantiated. The National Assessment Synthesis Team (NAST), with overall authority for the report, countered that much of the criticism it had received did not take into account the time scales upon which the report was based; the report targeted the effects of climate toward the middle of this century to the end of the next. Also, seemingly contradictory outcomes were produced by the two climate models selected for making the climate projections, casting some lingering doubt on the overall value and utility of the results for decision makers at the local, regional, and national levels. Various regional and resource-focused assessments are now available at the USGCRP website http://globalchange.gov/publications/371. A final synthesis report by the NAST, of the same title and consisting of an overview of all of the regional and sectoral studies, was released in December 2000."http://usinfo.state.gov/usa/infousa/tech/environ/9549.pdf


The National Assessment was attacked upon publication by the Competitive Enterprise Institute

 (CEI), an industry-funded think tank with an anti-regulatory free-market philosophy and a longstanding history of opposing efforts to address global warming. CEI filed lawsuits seeking to have the NACC report declared unlawful and to suppress its dissemination. These suits were dismissed "with prejudice," which means they had so little merit that they could not be refiled. In an interview, James R. Mahoney, admitted that the Climate Change Science Program has been constrained in its ability to use information in the National Assessment.

The NACC report has also been attacked by other industry-funded think tanks, including the American Enterprise Institute

. Its critics claim that the report is flawed in its methodology and conclusions, however, their assertions are not based on fact but rather political ideology .

In 2005, a group of scientists took a second look at the National Assessment and declared it a success.http://pubs.acs.org/subscribe/journals/esthag-w/2005/oct/policy/pt_grassroots.html Their report was published in the peer-reviewed journal, Environmental Science & Technology

Successors
