Handy Reference From Latest National Climate Assessment: US GHG Output By Sector

[hatrack]

Volume II of the Fourth National Climate Assessment (NCA4) is expected to be released soon. Written by more than 300 scientists, this report comes from the congressionally mandated U.S. Global Change Research Program (USGCRP), which was created with the passage of the Global Change Research Act of 1990. Volume I of NCA4, the Climate Science Special Report, was released last year, outlining the current understanding of the physical science behind climate change. Volume II: Impacts, Risks, and Adaptation in the United States assesses a range of climate change impacts and risks. These reports are part of the USGRCP effort across 13 U.S. Federal agencies to advance the science, communicate the results, and inform decision makers.



In addition to covering new scientific advances since the third NCA report in 2014, such as a new chapter on air quality at the national scale, this report will also shift its focus from national analyses to regional ones, as demand increases for more localized information on risks and impacts. New geographical sections have been added to illustrate impacts to the U.S. territories in the Caribbean and to other U.S. interests internationally. The report also increases coverage of economic impacts and interdependencies between regions.
