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. Highlights describe the state of science at the time of publication of each yearly report, and may not reflect more recent advances in understanding. The date of publication of the source report is noted on each highlight page.

Calm water snakes through a salt marsh surrounded by green vegetation on a sunny day.

Satellite data products are helping land managers quickly evaluate the health of vulnerable coastal wetlands.

Salt marshes protect communities and infrastructure from storms, filter pollution, and provide habitat for fish and shellfish. These coastal wetlands and the ecosystem services they provide are increasingly threatened by rising sea levels, erosion, and land use change, and land and resource managers need tools to track changes and trends in their health and extent. Satellite data products provide one method for quickly evaluating marsh vulnerability to environmental...

An aerial view of the Chesapeake’s Swan Island spotted with new marsh and dune plant growth, and its coasts lined with restored sediment.

Nature-based restoration efforts on Swan Island aim to protect coastal communities from erosion and storm surge while restoring ecosystems.

Coastal islands and marshes in the Chesapeake Bay provide habitat for many species and protect coastal communities from wave energy. Within the last half century, the effects of shoreline erosion, land subsidence, and sea level rise have accelerated the rate of island submergence and degradation of ecosystems in the region. In one example, the Smith Island complex, of which Swan Island is a part, has eroded at rates of up to 2 meters per...

Surveys of adaptation efforts adopted by businesses highlight opportunities for building resilience to complex climate events and other stressors.

Increases in the frequency and intensity of extreme climate and weather events put U.S. businesses at risk through closures, infrastructure damage, supply chain disruptions, and physical impacts on health and safety. The interaction among extreme events and other social and environmental stressors that affect U.S. businesses can lead to compound, simultaneous risks with impacts across multiple sectors that cause significant...

A researcher stands next to a large, horizontal stack of tree cross sections salvaged after a hurricane. Her hand rests on the trunk of one of the freshly-cut cross sections.

Studies of vulnerability to hurricane impacts in agriculture and forestry support efforts to reduce risks from future storms.

Three storms in the 2017 hurricane season caused catastrophic damage to communities, livelihoods, and infrastructure in the U.S. Southeast and Caribbean, including billions of dollars in losses in the agriculture and forestry sector. Climate change and other stressors are expected to increase damages and disruptions from hurricanes in the future, driving research to improve understanding of sector-specific vulnerabilities to storms and how best to...

A map of Oregon, Washington, Idaho, and part of western Montana showing patterns of aboveground biomass storage in forests. Overall biomass density is highest in western Washington and Oregon.

Mapping forest carbon stocks with in situ, airborne, and satellite data supports forest management in the western United States.

The Carbon Monitoring System (CMS), a NASA-led effort also involving the USDA Forest Service (USDA-FS), NOAA, the USGS, and non-governmental scientists, focuses on improving the monitoring of carbon stocks and fluxes (or the movement of carbon between the oceans, atmosphere, land, and ecosystems) to support carbon management activities. A CMS study is helping the USDA-FS and other...

The U.S. Midwest is a major producer of a wide range of food and animal feed for national consumption and international trade. Higher humidity, precipitation, and temperatures associated with a changing climate increasingly impact agriculture in the region, and projected climate changes are expected to pose growing challenges to agricultural productivity in the coming decades.^{^[1]}

Weather and climate information targeted to the needs of agricultural producers can help producers increase the resilience of their...

A natural-color image captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite on August 27, 2017, shows dozens of wildfires burning in the western United States.

Wildfires affect communities throughout the United States each year, threatening lives, property and infrastructure, and ecosystems.^[1] Understanding the climatic conditions that influence wildfire patterns can improve our ability to predict the occurrence and severity of future wildfires, and ultimately support the development of effective adaptation strategies.

In response to this need, multiple programs within the U.S. Geological Survey (USGS) and the Department of the Interior’s...

A king tide flooded parts of Imperial Beach, California in December 2018.

U.S. coastal communities are increasingly vulnerable to sea level rise, tidal flooding, higher storm surge, coastal erosion, and other climate-related impacts.^[1] To help communities in southern California plan for rising water levels, a NASA DEVELOP team collaborated with the U.S. Geological Survey’s (USGS) Pacific Coastal and Marine Science Center, in partnership with the California Coastal Commission, to create detailed projections of flooding from sea level rise and coastal storms along the...

Under Executive Orders (EO) 13514 and 13653, President Obama directed Federal agencies to evaluate and prepare for climate-related risks to ensure that they can continue to meet their missions and serve the American public as climate changes. A key component of USGCRP’s work to prepare the Nation for global change involves informing Federal preparedness and resilience efforts with resources built on sound scientific understanding.

To further support these efforts, USGCRP recently released an easy-to-access, web-based collection of resources to help Federal

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
