Fourth National Climate Assessment
Under scenarios with high emissions and limited or no adaptation, annual losses in some sectors are estimated to grow to hundreds of billions of dollars by the end of the century.
"[10] The other agencies included the DOA, DOC, DOD, DOE, HHS, DOI, DOS, DOT, EPA, NASA, NSF, Smithsonian Institution, and the USAID.
"[16] The Federal Science Steering Committee (SSC) for the CSSR included representatives from NOAA, NASA, and DOE, USGCRP and 3 Coordinating Lead Authors.
[17] The Federal Advisory Panel translating the NCA's scientific studies and findings into actionable public policy that individual states could implement to reduce emissions.
The panel was tasked with translating dozens of studies and scientific revelations that constitute the National Climate Assessment into policy actions that states could use to reduce greenhouse gas emissions.
[17] An article in The Atlantic said that the report "warns, repeatedly and directly, that climate change could soon imperil the American way of life, transforming every region of the country, imposing frustrating costs on the economy, and harming the health of virtually every citizen.
Under scenarios with high emissions and limited or no adaptation, annual losses in some sectors are estimated to grow to hundreds of billions of dollars by the end of the century.
"[9] The report cited a 2017 study, published in the journal Science, that estimated the economic damage to the U.S. economy in relation to increases in the global mean surface temperature (GMST).
[2] The report which analyzed the "effects of climate change by U.S. region",[21] emphasize[d] that "poor and marginalized communities" will be the most negatively "impacted by the intensifying storms and weather patterns caused by global warming.
The key message and supporting text summarizes extensive evidence documented in the peer-reviewed detection and attribution literature, including in the IPCC Fifth Assessment Report.
Walters called for future NCA reports to have a "more transparent and data-driven process that includes fuller information on the range of potential scenarios and outcomes".
[45] A November 23, 2018 Reuters article published in The New York Times cited the NCA4: "With continued growth in emissions at historic rates, annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century - more than the current gross domestic product (GDP) of many U.S.
"[48] An article in the Los Angeles Times said that the release of NCA4 was important in "tackling a misconception by many Americans that the changing climate doesn’t harm them personally."
"[3] Collin O'Mara, President of the National Wildlife Federation (NWF) issued a statement in which he called the timing of the Black Friday release by the White House of the NCA4 report—a month before its anticipated release—a "disgrace".
O’Mara said that, "It’s an absolute disgrace to bury the truth about climate impacts in a year that saw hundreds of Americans die during devastating climate-fueled megafires, hurricanes, floods, and algal blooms.
