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.

Analyses of the Effects of Global Change on Human Health and Welfare and Human Systems

A review of impacts of global climate change on three broad dimensions of the human condition: human health, human settlements, and human welfare. This report examines opportunities for adaptation and associated recommendations for addressing data gaps and near- and long-term research goals.

Effects of Climate Change on Energy Production and Use in the United States

This report summarizes the effects of climate change on energy production and use in the United States. It also identifies where research could reduce uncertainties about vulnerabilities, possible effects, and strategies to reduce negative effects and increase adaptive capacity.

Climate Change 2007: The Physical Science Basis

A comprehensive and up-to-date scientific assessment of past, present, and future global climate change. The assessment confirms that the scientific understanding of the climate system and its sensitivity to greenhouse gas emissions is now richer and deeper than ever before. The chapters forming the bulk of this report describe scientists assessment of the state-of-knowledge in their respective fields.

Excessive Heat Events Guidebook

The Environmental Protection Agency produced this publication with assistance from federal, state, local, and academic partners. It is designed to help community officials, emergency managers, meteorologists, and others plan for and respond to excessive heat events. The Guidebook highlights best practices that have been employed to save lives during excessive heat events in different urban areas.

Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences

This report addresses previously identified discrepancies between observations and simulations of surface and atmospheric temperature trends.  It is an important revision to the conclusions of earlier reports from the U.S. National Research Council and the IPCC.
