The recently released Preliminary Review of Adaptation Options for Climate Sensitive Ecosystems and Resources: Synthesis and Assessment Product 4.4 was prepared by a team of experts from governmental, academic, and nongovernmental organizations. USGS scientists Jill Baron and J. Michael Scott were lead authors of chapters on adaptation options for national parks and wildlife refuges, respectively. Other chapters address issues and adaptation responses suitable for wild and scenic rivers and national forests, estuaries, and marine sanctuaries. The report is the first of its kind to develop agency-specific recommendations for protecting valued natural resources in coming years. It examines the combined effects of climate changes and non-climate stressors on ecosystems and suggests management tools to reduce the risk of negative impacts, overcome barriers, and improve the likelihood of success. Results have been provided to the Intergovernmental Panel on Climate Change, and copies of the full report are being sent to Congress along with a fact sheet and transmittal letter inviting them to request briefings.
