The Second National Climate Assessment, entitled Global Climate Change Impacts in the United States, was published in 2009 and summarized the science of climate change and its impacts on America, now and in the future. It identified key climatic vulnerabilities of particular regions and sectors, in the context of other changes in the Nation’s environment, resources, and economy. It also identified potential measures to adapt to climate variability and change. Finally, the Second National Climate Assessment identified the highest priority uncertainties about which further study is needed to understand climate impacts, vulnerabilities, and America's ability to adapt.
