On November 23, 2018, the US government released Volume II of its Fourth National Climate Assessment report (NCA4), which "provide[s] a thorough examination of the effects of climate change on the United States." This report is a follow up to NCA4 Volume I, which was released in 2017 and focused on assessing the science of climate change. Among the many standout findings of NCA4 Volume II are that "[t]he impacts of climate change are already being felt in communities across the country" and that "annual losses in some economic sectors are projected to reach hundreds of billions of dollars by the end of the century" without substantial efforts to mitigate and adapt to climate change. Readers can download the 196-page report in brief in both English and Spanish as a PDF, as well as an eight-page summary containing a high-level synthesis of the report's findings. Individual full-length PDFs of the report's 29 chapters with accompanying PowerPoint slides are also available, as are PDFs of its public reviews and FAQs. NCA4 was produced by Congressional mandate under the Global Change Research Act of 1990, and the National Oceanic and Atmospheric Administration led the thirteen federal agencies involved in its preparation.
