Highlights

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.

DYNAMO: Linking Observations and Models to Predict Near-Term Climate

 The NASA GEOS5 model has made significant progress in simulating the MJO, demonstrated by how closely its output (right panel) visually resembles satellite observation data (left panel; in both panels, MJO events are represented as lines of green, red, a

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’

Empowering the Nation with Climate Data

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

Indicators

Tracking Climate Change with Indicators

“Indicators” are variables that can be used to measure the status or trend of a system. Indicators of climate-related global change—whether ecological, physical, or societal—can be used to track and communicate key aspects of the changing environment, point out vulnerabilities, and inform decision making at local, state, and national levels.

A pilot set of climate indicators is being developed collaboratively by USGCRP agencies including NASA, NOAA, EPA, USDA, DOE, DOD’s U.S. Army Corps of Engineers (USACE), CDC, and DOI. The

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.

Modeling 20th and 21st Century Climate to Understand and Predict Change

A comparison of observed (left) and simulated (right; single model realizations) hurricane tracks around North America between 1981 and 2008 (the horizontal and vertical axes show longitude and latitude, respectively). Tropical cyclones are challenging to

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

Developing Indicators of Climate Change

This conceptual framework shows linkages between categories of indicators. (Source: USGCRP indicators program)

Overview
Indicators are measurements or calculations that represent the status, trend, or performance of a system (e.g., the economy, agriculture, air quality). USGCRP, with the participation of 9 of its 13 member agencies—NOAA, NASA, EPA, USDA, DOE, DOD’s U.S. Army Corps of Engineers (USACE), HHS’s
