Global Climate Change Impacts in the United States Cover

Global Climate Change Impacts in the United States (2009)

Climate changes are underway in the United States and are projected to grow. Consequently, crops and livestock production will be increasingly challenged and threats to human health will increase. These are two key findings presented in this 2009 assessment report by the U.S. Global Change Research Program. The report gives an overview of climate-related issues and impacts for seven geographical regions and seven sectors of society.

Scanning the Conservation Horizon: A Guide to Climate Change Vulnerability Assessment

A guide released by the National Wildlife Federation in 2011 for conservationists and resource managers to help them understand and assess the impact of climate change on species and ecosystems, including fisheries.

Atmospheric Aerosol Properties and Climate Impacts

A detailed look at global distributions and properties of airborne particles known as "aerosols." The report examines the various ways in which aerosols influence climate, and the uncertainties in our ability to observe and measure these particles' impact on the climate system.

Thresholds of Climate Change in Ecosystems

An assessment of the potential for abrupt state changes or regime shifts in ecosystems in response to climate change.  Better understanding of sudden changes to ecosystems, and the goods and services they provide, is extremely important if natural resource managers are to succeed in developing adaptation strategies.

Best Practice Approaches for Characterizing, Communicating, and Incorporating Scientific Uncertainty in Decision Making

A tutorial for the climate analysis and decision-making communities on current best practices in describing and analyzing uncertainty in climate-related problems. Uncertainty is ubiquitous. Of course, the presence of uncertainty does not mean that people cannot act.

Strategies to Promote Commercialization and Deployment of Greenhouse Gas Intensity-Reducing Technologies and Practices

This report systematically examines the market readiness of key technologies important to meeting climate change mitigation goals.  It assesses the barriers and business risks impeding their progress and greater market application.  The report was sponsored by the U.S. Climate Change Technology Program (a multi-agency group led by the U.S. Department of Energy) and was submitted to the President and Congress in January 2009.

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.
