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.
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.
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.
Preliminary Review of Adaptation Options for Climate-Sensitive Ecosystems and Resources
June 19, 2008
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
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.
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.
