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.
A new tool makes satellite data on field conditions available to producers.
Soil moisture data are used to plan crop planting, forecast yields, track droughts or floods, and improve weather forecasts, and can also be used to track changing conditions for U.S. agriculture over time. A new tool developed by USDA makes soil moisture data from NASA available to farmers, researchers, and other users.
The Crop-CASMA (Crop Condition and Soil Moisture Analytics) tool uses high-resolution...
New data products integrate multiple sources of soil moisture information to improve drought monitoring and prediction.
Drought is one of the most destructive and costly natural disasters, resulting in diminished agricultural production, reduced water resources, and deadly heatwaves. NOAA and the National Integrated Drought Information System have supported interagency activities to develop a national-scale drought product that integrates multiple sources of soil moisture...
A new resource ensures that Federal health and climate research is accessible to inform the Fifth National Climate Assessment.
In 2020, the CCHHG began an effort to identify and organize information on federally funded research activities on climate change and human health since 2016. This group, co-led by EPA and NASA, collated this information into a Federal climate change and health research compendium document to help inform authors of the Fifth National...
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...
Researchers used interagency modeling and observational capabilities to understand the impacts of reduced pollution related to the COVID-19 pandemic on Earth’s energy balance.
Lockdown measures enacted to control the spread of COVID-19 led to a worldwide reduction in emissions of tiny atmospheric particles known as aerosols. Through their interactions with solar energy and clouds, aerosols play a significant role in shaping Earth’s energy balance (or the balance between incoming energy from the sun and outgoing energy from the Earth) and climate that is still inadequately...
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...
Recent studies are improving the ability to quantify ecosystem carbon dynamics and greenhouse gas exchange in changing Arctic and boreal landscapes.
Northern high latitudes are warming at more than twice the global average, driving permafrost thaw, changes in surface water extent, increased wildfire, and other changes that affect how much carbon is stored in and emitted to the atmosphere by soils, vegetation, and inland waters.[1] Measuring the flow of carbon between ecosystems, landscapes, and the...
An interagency field campaign gathered data on interactions between the tropical ocean and atmosphere to improve weather and climate prediction.
Over the tropical ocean, interactions between winds and warm sea water form low-hanging clouds (known as shallow convective clouds) that act as the building blocks for storms. These clouds and air–sea interactions influence weather and climate conditions all over the world, but are poorly represented in models, in part due to a lack of detailed observations that are needed to understand and accurately simulate their behavior. In...
New ocean sensors will expand the ability of the global Argo Program to monitor and forecast changes in ocean chemistry and marine ecosystem health.
The international Argo Program maintains a global fleet of nearly 4,000 ocean floats that help scientists understand how the ocean is changing over time. Underwater sensors provide data on trends related to climate change, including ocean temperature and heat content, salinity and freshwater content, sea level, and large-scale ocean circulation. Now, the program is innovating...
