Coastal Sensitivity to Sea Level Rise: A Focus on the Mid-Atlantic Region
January 16, 2009
Global sea level is rising at an accelerating rate. This report examines the implications of rising sea level, with a focus on the U.S. mid-Atlantic region, where storm impacts occur and there is a large extent of critical habitat, high population densities, and infrastructure in low-lying areas.
Past Climate Variability and Change in the Arctic and at High Latitudes
January 1, 2009
Over the past 30 years, average temperatures in the Arctic have increased at almost twice the rate of the planet as a whole. Such temperature changes have been accompanied by shrinking sea ice, melting ice and permafrost on land, and widespread impacts to land and ocean ecosystems.
Decision-Support Experiments and Evaluations Using Seasonal-to-Interannual Forecasts and Observational Data: A Focus on Water Resources
November 13, 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.
Analyses of the Effects of Global Change on Human Health and Welfare and Human Systems
July 1, 2007
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.
Temperature Trends in the Lower Atmosphere: Steps for Understanding and Reconciling Differences
April 1, 2006
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.
An international project of the Arctic Council and the International Arctic Science Committee, the Arctic Climate Impact Assessment evaluates and synthesizes knowledge on climate variability, climate change, and increased ultraviolet radiation and their consequences for the Arctic region.
