Progress Report of the Interagency Climate Change Adaptation Task Force: Recommended Actions in Support of a National Climate Change Adaptation Strategy [open pdf - 1MB]
"As concentrations of greenhouse gases and heat-trapping particles increase in the atmosphere, it is becoming ever more urgent to understand and prepare for the resulting changes in climate. These changes include not only temperature increases but also shifts in precipitation patterns, storm tracks, and other parameters. Climate change affects human health, water and energy supplies, food production, coastal communities, ecosystems, and many other aspects of society and the environment. The Obama Administration is committed to reducing greenhouse gas emissions to minimize the impacts of climate change. But mitigation alone is not enough. People are already feeling the impacts of climate change and future changes are inevitable. To prepare and respond to these impacts, the Administration is also committed to climate change adaptation."
