Accomplishments of the U.S. Global Change Research Program
Established under the Global Research Act of 1990, the U.S.
One of the first priorities of the program was to address the need for a global observational system. Today there is a large and growing portfolio of global measurements from space designed to inform global change science. Other demonstrable contributions of USGCRP include significant improvements in Earth-system modeling capabilities and advancement in understanding of carbon-cycle processes. USGCRP has also made considerable strides in making scientific knowledge more useful to decision makers. For example, it has documented substantial increases in heavy downpours in most regions of the United States over the past 50 years, which can cause flooding that overwhelms the existing infrastructure of sewers and roads. Awareness of such trends can help governments, businesses, and citizens respond accordingly in many realms, including agriculture, conservation, and human health.
