Coastal Sensitivity to Sea Level Rise: A Focus on the Mid-Atlantic Region
January 15, 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.
An assessment of abrupt climate change events where key aspects of Earth's climate system change faster than the responsible forcings would suggest and/or faster than society can respond. This report examines four types of abrupt change in Earth's past that were so rapid and so large in their impact that if they were to recur today they would pose clear risks to society in terms of our ability to adapt.
Climate Projections Based on Emissions Scenarios for Long-Lived and Short-Lived Radiatively Active Gases and Aerosols
September 3, 2008
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.
Weather and Climate Extremes in a Changing Climate
May 31, 2008
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
May 26, 2008
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.
