"In 1990, Congress passed the U.S. Global Change Research Act (GCRA of 1990, Section 102, P.L. 101-606), creating the U.S. Global Change Research Program (USGCRP) with a mandate to 'assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change.' More than two decades later, USGCRP continues to play a pivotal role in coordinating and integrating scientific research, information, tools, and technologies across the Federal Government. In June 2013, President Obama launched a comprehensive Climate Action Plan that called for sound science to manage the impacts of climate change. Many elements of the Plan - including Developing Actionable Science, Assessing Climate Change Impacts in the United States, Launching a Climate Data Initiative, and Providing a Toolkit for Climate Resilience - build on the tenets of the GCRA and will be supported by USGCRP's ongoing and planned investments in science, assessment, and decision support. As a whole, the GCRA, the President's Climate Action Plan, and the Federal Government's continued investment in USGCRP mark an important and enduring recognition that global change is happening and that action is needed to understand and address the increasingly severe climate-change impacts affecting our Nation. 2012 was the hottest year ever in the contiguous United States. Globally, nine of the 10 hottest years on record have occurred in the 21st century."
