Apart from serving scientists studying global change, output from the Coupled Model Intercomparison Project (CMIP; see related Highlight 7) can be useful to decision makers confronting regional and local climate impacts. A number of USGCRP agencies have supported the “downscaling” of CMIP output to provide climate information on scales of space and time that are relevant to decisions facing resource managers and planners. Downscaled data permit a range of analyses, such as evaluation of uncertainty in

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.
Pollution from the combustion of fossil fuels and wood has contributed to climate change in complex ways, with some pollutants causing cooling and others causing warming, accompanied by effects on patterns of atmospheric circulation and precipitation. To better understand these complex relationships, the Atmospheric Chemistry Climate Model Intercomparison Project, part of the international 5th-phase Coupled Model Intercomparison Project (CMIP5), conducted a series of pollution-focused modeling experiments to reveal spatial patterns, sectoral influences,
Predicting climate conditions anywhere from two weeks to a season in advance is critical for making informed decisions and safeguarding infrastructure across various sectors of the U.S. economy, including water resources, energy supply, public safety, and agriculture, among many others.
USGCRP agencies are supporting improved climate forecasts on these relatively short timescales through field campaigns coupled with model development and analysis efforts. DOE, NASA, NOAA, NSF, and DOD’

USGCRP’s novel Global Change Information System builds on prior agency investments and is designed to support traceability between multiple environmental data streams—such as observations from sensors and output from models—and the resulting scientific reports. This system creates an open environment for users to access machine-readable information and trace user-friendly products back to the supporting science. As an important first step and proof-of-concept, the GCIS provides this
In March 2014, USGCRP helped support the launch of the Climate Data Initiative, a key component of the President’s Climate Action Plan. The Climate Data Initiative brings together open government data with commitments from the private and philanthropic sectors to develop data-driven tools that communities and businesses across America need to plan for the impacts of climate change.
With the launch of the Climate Data Initiative, data from USGCRP agencies—including NOAA, NASA, USGS, and DOD—and other Federal entities are
With the release of the Third National Climate Assessment (see related Highlight 9) came a spike in public demand for information about climate change, its impacts on America, and USGCRP. The Program met this press of interest with a new user-friendly, public-oriented website that launched concurrently with the report’s release. The site deploys the Third National Climate Assessment in an interactive, shareable format. It also provides a dynamic suite of resources and information spanning the breadth of USGCRP and serving user groups including scientists, decision

Overview
A series of Earth observation missions planned by NASA and partners for FY 2014 will contribute fundamentally to advancing our understanding of global change. Such missions are foundational to USGCRP research and are made possible by a sustained Program emphasis in instrumentation development. The planned FY 2014 missions are described below.
Overview
A number of USGCRP agencies such as NSF, DOE, NOAA, NASA, USGS, and SI are investing in understanding the history of Earth’s climate, known as “paleoclimate.” Paleoclimate data extend records of climate
Overview
The North American Multi-Model Ensemble (NMME)—led by NOAA in partnership with DOE, NSF, NASA, and U.S. and Canadian research institutions—is an experimental climate forecasting system that combines a suite of different models. Using a combined system of models, each with different individual strengths in predicting phenomena, can enhance the overall success of a
Overview
Climate and Earth system modeling supported by USGCRP agencies such as DOE, NASA, NOAA, NSF, and others was foundational to the IPCC’s Fifth Assessment Report (AR5) on the scientific basis for climate-change, released in 2013. Along with international partners, Federal and Federally supported modeling centers
