Human activities, in the United States and elsewhere, contribute to the emission of greenhouse gases, which persist in the global atmosphere and lead to climate change, including global warming and other climate variability. The United States has begun to cooperate more fully with international measures to mitigate climate change, but has not yet enacted comprehensive climate legislation. Nonetheless, federal statutes and regulations in the areas of environmental, energy, and climate law help to reduce greenhouse gas emissions and to mitigate climate change. States have also adopted measures to mitigate climate change, and several regional programs exist. Although fewer regulatory efforts in the United States have focused on adaptation to climate change, both the federal government and the states will require programs to adapt to the effects of unavoidable climate change.
