The US National Assessment of the Potential Consequences of Climate Variability and Change divided the country into regions (listed to the left), each with its own Assessment Group.  In most cases, the Assessment Groups organized "regional scoping workshops" and generated reports for each region (see workshops page for additional information on the workshops).

A separate "Synthesis Team" consolidated many of these regions to form larger "mega-regions" (listed above) around which its Overview and Foundation reports are organized.  In most cases, if you want information on a particular area of the country, you should start with the Mega-Regions.  Note that 2 of the regions (Alaska and Pacific Northwest) are not consolidated with other regions and are considered stand-alone mega-regions in the Synthesis Team's reports.

For summaries of climate impacts organized by state, see also the US Environmental Protection Agency's State Impacts site.  See also:

The National Assessment Overview and Foundation Reports were produced  by the National Assessment Synthesis Team, an advisory committee chartered under the Federal Advisory Committee Act, and were not subjected to OSTP's Information Quality Act Guidelines. The National Assessment was forwarded to the President and Congress in November 2000 for their consideration.
