This report is the Second National Climate Assessment. It summarizes the science of climate change and the impacts of climate change on the United States, now and in the future.
Informing Decisions in a Changing Climate examines the growing need for climate-related decision support—that is, organized efforts to produce, disseminate, and facilitate the use of data and information in order to improve the quality and efficacy of climate-related decisions. Drawing on evidence from past efforts to organize science for improved decision making, it develops guidance for government agencies and other institutions that will provide or use information for coping with climate change.
This report, the First National Climate Assessment, includes analyses of the importance of climate variability and change for twenty regions around the United States, for five cross-cutting sectors, and for the United States as a whole. The DVD contains background information, public review drafts and final reports, citations, and high-resolution images.
Climate Literacy: The Essential Principles of Climate Science presents information that is deemed important for individuals and communities to know and understand about Earth’s climate, impacts of climate change, and approaches to adaptation or mitigation. Principles in the guide can serve as discussion starters or launching points for scientific inquiry.
