Decision-Support Experiments and Evaluations Using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources

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

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.

Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols

An assessment of the effects of short-lived gases and particles in the atmosphere. They can significantly change regional surface temperatures. By the year 2100 short-lived gases and particles may account for as much as 40 percent of the warming over the continental U.S. in summertime.

Climate Models: An Assessment of Strengths and Limitations

Scientists use mathematical models of Earth's climate, run on the most powerful computers available, to examine hypotheses about past and present-day climates. This report describes the models and their ability to simulate climate.

Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources

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.

Weather and Climate Extremes in a Changing Climate

An assessment in the state of knowledge concerning changes in weather and climate extremes in North America and U.S. territories. Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate.

Weather and Climate Extremes in a Changing Climate

An assessment in the state of knowledge concerning changes in weather and climate extremes in North America and U.S. territories. Changes in extreme weather and climate events have significant impacts and are among the most serious challenges to society in coping with a changing climate.

The Effects of Climate Change on Agriculture, Land Resources, Water Resources, and Biodiversity in the United States

An assessment of the effects of climate change on U.S. land resources, water resources, agriculture, and biodiversity. There is robust consensus that human-induced climate change is occurring. This report discusses the nation's ability to identify, observe, and monitor climate-related stresses that influence agriculture, land resources, water resources, and biodiversity.

Reanalysis of Historical Climate Data for Key Atmospheric Features: Implications for Attribution of Causes of Observed Change

A reanalysis combines a diverse array of past observations together within a model to derive a best estimate of how the climate system has evolved over time. The goal is to provide consistent and reliable long-term datasets of temperatures, precipitation, winds, and many other climate variables.

EPA BASINS 4.0 Climate Assessment Tool

A tool that integrates geographical information, watershed data, and state-of-the-art modeling tools. Specifically, BASINS CAT provides flexible capabilities for creating climate change scenarios allowing users to quickly assess a wide range of "what if" questions about how weather and climate could affect their systems.
