This animation shows predicted changes in temperature across the globe, relative to pre-industrial levels, under two different emissions scenarios in the COP 17 climate model. The first is with emissions continuing to increase through the century. The second is with emissions declining through the century.
Global Sea Level Rise Scenarios for the United States National Climate Assessment
December 6, 2012
Global sea level has been steadily rising for decades and is expected to continue. Scientists have very high confidence that global sea level will rise at least another 8 inches and as much as 6.6 feet by 2100, causing significant impacts in U.S. coastal regions. This report lays out the science and describes possible scenarios to help planners and policy leaders assess the risks.
Coastal County Snapshots turn complex data into easy-to-understand stories, complete with charts and graphs. Users select a coastal county of interest and the website does the rest, providing information that can help communities become more resilient to coastal hazards.
Much of the nation’s experience to date in managing and protecting its people, resources, and infrastructure is based on the historic record of climate variability during a period of relatively stable climate. This report from the America’s Climate Choices suite of studies concludes that adaptation to climate change calls for a new paradigm--one that considers a range of possible future climate conditions and associated impacts, some well outside the realm of past experience.
Greenhouse gas emissions and increased global temperature will change weather, climate, ecosystems, and food supply. Each degree Celsius (1.8 deg Fahrenheit) increase in global average temperature (up to 4 deg C) would likely result in the following: 5% to 10% less total rain in southwest North America, the Mediterranean, and southern Africa; 5% to 10% less streamflow in some river basins; 5% to 15% lower yields of some crops. The document clarifies short- and long-term consequences of various scenarios.
Global Climate Change Impacts in the U.S. (Agriculture)
June 16, 2009
A chapter from the 2009 U.S. Global Change Research Program (USGCRP) report, titled Global Climate Change Impacts in the United States, focused specifically on the intersections of climate and agriculture.
Decision-Support Experiments and Evaluations Using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources
November 12, 2008
An evaluation of decision support experiments that have used seasonal-to-interannual climate forecasts and observational data. Earth's climate varies naturally and also changes in response to human activity. Our ability to adapt and respond to climate depends on our understanding of the system and how to incorporate this understanding into resource management decisions.
Uses and Limitations of Observations, Data, Forecasts, and Other Projections in Decision Support for Selected Sectors and Regions
September 8, 2008
Scientific information about Earth's climate, water, air, land, and other dynamic processes is essential for our understanding of humankind's relationship to our natural resources and our environment. This report examines contributions of Earth science information in decision support activities and their relationship to climate change science.
Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources
June 19, 2008
A review of adaptation options for climate-sensitive ecosystems and resources in the United States. This report focuses on the following selected land management systems: National Forests, National Parks, National Wildlife Refuges, Wild and Scenic Rivers, National Estuaries, and Marine Protected Areas.
