Fourth national climate assessment, Volume II: Impacts, risks, and adaptation in the United States

sheeja's picture

The Fourth National Climate Assessment (NCA4) fulfills a US congressional mandate to report on climate change in the United States every four years, and contains two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report (CSSR), which was published in 2017. Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods.
