American Geophysical Union experts available to comment on the Fourth National Climate Assessment

23 November 2018

WASHINGTON, DC — The U.S. Global Change Research Program today released the Fourth National Climate Assessment Volume II: Impacts, Risks, and Adaptation in the United States (NCA4 Vol. II).

The report is an authoritative assessment of the impacts of climate change on the U.S. and its territories, and was written to help decision-makers, utility and resource managers, public health officials, emergency planners, and other stakeholders better understand the effects of climate change on the United States. This new report builds on the 2017 Climate Science Special Report (CSSR), Volume I of the Fourth National Climate Assessment.

Read a summary of the report written by some of the report’s authors on and a statement about the report from AGU Executive Director and CEO Chris McEntee on From the Prow.

Several AGU scientists are available to comment on the report and the science behind it (see experts for the media below).

AGU will also hold several scientific sessions on the report and its key findings at the upcoming AGU Fall Meeting being held 10-14 December in Washington, D.C. These sessions include:

Members of the media can find additional information about the Fall Meeting, including registration information, on the Fall Meeting Media Center.
