A massive two-volume effort from the U.S. Global Change Research Program that was mandated by the U.S. Congress, and thus escaped the head-in-sand climate change denial of the Trump administration.

Volume 1: Climate Science Special Report (2017, 470p; 23p Summary), provides a non-technical overview of US and global climate change–past, present, and future–with projections and scenarios of temperature and precipitation change, drought and floods, extreme storms, Arctic change, sea level rise, and potential surprises.
Volume 2: Impacts, Risks, and Adaptation in the United States (Nov 2018, 1,515p; 86p Report-in-Brief with 8p Summary) provides an excellent survey of economic and social areas that will be increasingly imperiled, as well as detailed assessment of projected changes in 10 U.S. regions.  Growing impacts and risks are described for water and energy supply, land use, forests, ecosystems and biodiversity, oceans, high tide flooding of coastal areas, agriculture and rural communities (productivity decline expected, especially in the Midwest), built environment and cities, infrastructure and property losses, transportation, air quality, threats to human health, threats to indigenous peoples, U.S. international interests, and sector interactions.  Although Volume 2 is limited to the U.S., the framework for assessing rising costs of climate change, and where encountered, could be applied to any large country or region.
