The report also indicates future trends for U.S. GHG emissions, outlines the impacts of climate change on the United States and the adaptation measures the nation is taking to address those impacts, provides information on climate-related financial resources and technology transfer, details U.S. research and systematic observation efforts, and describes U.S. climate education, training, and outreach initiatives. The activities in this report outline a set of initiatives in an ambitious, sustained effort that will be required to fully address climate change. The United States, in close cooperation with other nations of the world, is ready to build on its actions to date and assume a leadership role in this effort. The United States will continue to vigorously develop and build on its domestic and international efforts in coming months and years."
