Climate change represents one of the greatest challenges of our time. The impacts of climate change are already being felt across the United States and around the world, increasing the frequency and severity of natural disasters, causing harm to both human and ecological health, and threatening our property, infrastructure, national security, and overall quality of life. While no single step can reverse the effects of climate change, the President has taken unprecedented action to address this critical issue, including outlining a comprehensive strategy to mitigate, prepare for, and lead global efforts to fight climate change under the Climate Action Plan; limiting carbon pollution from power plants under the Clean Power Plan; and leading a historic trip to the Arctic to raise awareness of the impacts of climate change.

The 2016 White House Science Fair on April 13, 2016, was the biggest yet, including more than 130 students from more than 30 states. Learn more:


The Obama Administration believes that responsible openness in government and data strengthens our democracy, fuels innovation, and promotes efficiency, effectiveness, and accountability. On his first day in office, President Obama signed a Memorandum on Transparency and Open Government, directing the development of an Open Government Directive to instruct executive departments and agencies to take specific actions to advance the principles of transparency, participation, and collaboration. Since then, the Obama Administration has continued to drive progress on these principles, including through the release of an Executive Order on making open and machine-readable data the new default for government information, and issuing a periodically updated Open Government National Action Plan.
