The 148-page Highlights book presents the major findings and selected highlights from Climate Change Impacts in the United States: The Third National Climate Assessment. The Highlights report is organized around the National Climate Assessment’s 12 Report Findings, which take an overarching view of the entire report and its 30 chapters.
The two-volume report from the IPCC's Working Group II 1) assesses risks and opportunities for societies, economies, and ecosystems around the world, and 2) considers unique features of major world regions.
This report summarizes the Working Group II contribution to the IPCC's Fifth Assessment Report on climate change. It considers the vulnerability and exposure of human and natural systems, the observed impacts and future risks of climate change, and the potential for and limits to adaptation.
This 20-page booklet provides a high-level compendium of Climate Change Impacts in the United States: The Third National Climate Assessment. The Overview covers the most important impacts at the national level but does not attempt to provide a comprehensive summary of the entire assessment.
