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.

Past Climate Variability and Change in the Arctic and at High Latitudes

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

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.

Arctic Climate Impact Assessment

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.
