Since 1989, the U.S. Global Change Research Program (USGCRP) has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments.

In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement.

Much of the precipitation along the U.S. West Coast is delivered by phenomena known as “atmospheric rivers”—narrow bands of moist air that may extend for thousands of miles across regions outside of the tropics, and play a critical role in regional water supply and storm activity. Atmospheric-river events play a beneficial role in building up Western water supply and snowpack but are...

Since 2011, California has experienced one of its most severe and widespread droughts since record-keeping began in 1895. USGCRP-supported research helps advance drought science and provides the basis for the National Integrated Drought Information System (NIDIS) (Highlight 10), which aims to increase the capacity of the public to better prepare...

Green infrastructure projects, such as this stormwater planter, help to collect and absorb runoff, among other benefits. Local-level capacity and reliable cost-benefit information are needed to effectively incorporate such solutions into stormwater manage

Water resources in the United States are affected by a number of climate stressors—including increasing temperatures, changing precipitation patterns, and extreme events like storms and droughts—and these changing conditions have implications for drinking water and stormwater utilities. Federal agencies are working with one another and

The severe, sustained drought affecting the Central Valley of California has caused a shortage of water for irrigation and crop production. The effect of this shortage is most immediately evident as an increase in the extent of fallowed farmland (or land taken out of agricultural production), which in turn serves as a proxy for socioeconomic impacts. Decision makers can use

In the Southwest, reservoirs such as Lake Powell (above) have reached record-low levels in recent periods of drought. Training for water resource managers is an essential step in preparing for hydrologic extremes in a changing climate.

Climate change presents new challenges for managing water quality and quantity, particularly in areas where water resources are already stressed. Resource managers need scientifically sound, usable

Trout and salmon are economically and ecologically important stream-dwelling species. Researchers from USGS, NOAA, and the University of Montana are working together to assess the effects of current and future

The NMME (yellow column) is a seasonal forecasting system that combines individual models (purple columns N1-N6) to produce more accurate predictions of climate. In forecasts of precipitation (top two panels) and temperature (bottom two panels)—key factor

Drought is a significant hazard for the United States, with potentially severe and long-lasting impacts on the Nation’s economy and food and water supplies. USGCRP agencies are advancing our understanding of the causes and consequences of drought, an FY 2015 interagency research priority (see Section 4). They are also collaborating in efforts to support drought

Overview
The 2011–2012 U.S. drought was the most severe and extensive in at least 25 years, and the effects are still being felt in some areas of the Nation. Recently, USDA partnered with local governments, colleges, and state and Federal partners— including
