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.

A journal special issue highlights advances in the science of protecting species and ecosystems from climate change impacts.

An increasingly important climate change adaptation strategy is to focus conservation on climate change refugia, or areas that are relatively buffered from contemporary climate change. Protection and management of climate change refugia can help shelter native species and ecosystems from current climate change impacts and provide longer-term havens that protect valued ecological and sociocultural resources. The U.S. Geological Survey and EPA,...

The Climate Change Response Framework provides landowners with adaptation options to address climate change risks to forests.

Climate change increases uncertainty about future conditions affecting land and natural resources, creating new challenges for land managers working to sustain healthy ecosystems and ecosystem services. In 2020, the Northern Institute of Applied Climate Science (NIACS) and the USDA Northern Forests Climate Hub worked side-by-side with land managers to advance regionally specific climate change adaptation strategies. The NIACS...

A close-up shot of an emerald ash borer clinging to the side of a twig. Its metallic brown-green stands out against the blurred, wooded background.

A new scientific assessment provides information on the spread and control of invasive species for land managers.

The spread of invasive species is recognized as a major driver of biodiversity loss and a source of substantial economic and environmental damage. Global environmental changes, including climate change and land use change, continue to influence how invasive species spread and interact with ecosystems, presenting new and ongoing challenges for land managers. A recent USDA Forest Service (USDA-FS) ...

Dried, brown corn stalks wilt under the sun in cracked soil from the effects of extreme heat and drought.

The Drought Learning Network supports knowledge exchange on drought management in the U.S. Southwest.

The Drought Learning Network (DLN) brings together drought management leaders and resource managers to support knowledge sharing and improve collaboration around building resilience among communities impacted by drought in the U.S. Southwest, one of the hottest and driest regions of the world. The DLN was created by drought management leaders from the USDA Southwest Climate Hub, the National...

A straight-on view of unsettled water flowing through the All-American Canal, the Southern Californian landscape framing both of its sides.

Collaborative studies among scientists and decision-makers are identifying strategies to meet current and future water demands.

The western United States faces growing water challenges. Drought, population change, aging infrastructure, and ecosystem needs all strain existing water and power infrastructure, and future climate change is expected to further...

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...
