US Global Change Research Program, 841 pp. doi:10.7930/J0Z31WJ2 2SMEs should consult the regional section of GCRP (2014) and other appropriate sources for information on the extent and direction of the anticipated changes in the region of interest.

3Includes heat waves, cold waves, and regional droughts 4Includes projection of summertime Arctic Ocean sea ice essentially disappearing before mid-century 5Includes saltwater intrusion and other impacts related to sea level rise, storms and storm surges, and changes in surface and groundwater use patterns 6Includes changes due to increasing air and water temperatures, more intense precipitation and runoff, increasing droughts, and increased sediment and pollutant loadings 7Includes effects on human safety and health, property, infrastructure, economies, and ecology 8Includes impacts from sea level rise, storm surge, extreme weather events, higher temperatures, heat waves, precipitation changes, Arctic warming and other climatic conditions 9Includes temporary and permanent flooding of airports, ports and harbors, roads, rail lines, tunnels, and bridges 10Includes both transportation interruptions and infrastructure damage (e.g., pavement and track damage) due to extreme heat, strong hurricanes, coastal erosion, permafrost thaw, etc.

11Includes increasingly negative impacts on crops and livestock due to responses to elevated CO2, increased temperatures, changes in solar radiation, etc.

12Includes effects of fire, insect infestations, drought, disease outbreaks, etc.

13Includes shifts in ranges of species; increased incidence of insect pests, disease pathogens, and invasive weed species; effects of hotter and dryer deserts and drylands; impacts of ocean acidification on coastal and near-shore ecosystems; impacts of Arctic summer sea ice loss; impacts of warming on fish, plant, and animal species; etc.

14Includes spring bud burst, migration, hibernation, emergence from overwintering, plankton blooms, etc.

15Includes whole system management and ecosystem-based adaptation strategies 16Includes impacts from increased extreme weather events, wildfire, decreased air quality, threats to mental health, illnesses transmitted by food, water, disease-carriers such as mosquitos and ticks and other etiological agents 17Includes children, the elderly, the poor, and some communities of color 18Rural economic activities include agriculture, forestry, recreation, etc. Impacts include shifts in locations of such activities.

19Vulnerabilities include geographic and demographic obstacles, such as physical isolation, limited economic diversity, higher poverty rates, aging population, etc.

20Includes ability to adapt rural transportation, infrastructure, health, and emergency response systems 21Includes alterations due to increased atmospheric carbon dioxide and changes in nitrogen, phosphorous, and other elements available to ecosystems Page36
