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.

Researchers are improving understanding of how shifts in climate conditions affect agricultural production, as well as the value of providing advance climate information to producers.

Climate variability and change affect agricultural yields and livelihoods^[1]. Improving our understanding of how the interaction of climate variability and change affects agricultural production, particularly on regional scales that are more relevant to decision making, is an important research frontier. As part of the joint NSF-USDA...

Collaboration across the modeling community supports critical experiments and scientific advancement.

U.S. climate modeling centers play a central role in understanding and predicting global change on seasonal to centennial timescales. They are engaged in the Coupled Model Intercomparison Project (CMIP), which produces climate projections underpinning the assessments conducted by the Intergovernmental Panel on Climate Change and the U.S. National Climate Assessment. Models developed by these centers are designed for different purposes, from providing operational forecast...

The Ten Thousand Islands mangrove ecosystem in the Florida Everglades pictured before (top, March 28, 2017) and after (bottom, December 1, 2017) Hurricane Irma

Interagency collaboration supported recovery efforts after Hurricanes Irma and Maria.

During the 2017 hurricane season, hurricanes Irma and Maria, two of the most significant storms to affect Florida and the U.S. Caribbean in recent history, caused catastrophic damage that affected ecosystems, livelihoods, and economic stability throughout the region. USGCRP provided one venue for facilitating interagency efforts—involving USDA, DOE, NASA, NSF, DOI, and FEMA—that are tracking storm damage and recovery in forests and the agricultural sector and supporting recovery and...

A lake near Fairbanks, Alaska shows signs of thawing permafrost below the surface

By monitoring trends such as permafrost thaw, shifts in wildfire, and changing wildlife habitats, a multi-year field campaign seeks to provide the scientific basis for informed decision-making in response to change.

Climate change in the Arctic and Boreal Region is unfolding faster than anywhere else on Earth. Observations reveal reduced Arctic sea ice, widespread changes to coastlines and waterways, thawing of permafrost soils and decomposition of long-frozen organic matter, and shifts in ecosystem structure and function. These changes have far-reaching impacts in the...

The Strawberry Advisory System tool, which shows risk levels for climate-related disease in strawberry crops, helps growers make decisions about fungicide application.

Interagency efforts develop and deliver science-based information and technologies to help agricultural producers and natural resource managers make optimal management decisions.

Farmers, ranchers, and land managers across the country rely on weather and climate information in their management decisions. To help producers and managers better understand the risks and opportunities that extreme weather events and climate change present for their operations, interagency efforts produce and deliver a range of information tools and resources that help guide climate risk...

Monitoring tools help resource managers prepare for and reduce the impacts of drought.

The impacts of drought on water resources, plants and wildfire, agriculture, and the economy are complex and occur over many timescales, underscoring the value of a range of drought monitoring tools that support different types of decisions. To help meet this need, two complementary weekly drought monitoring and mapping tools—the Vegetation Drought Response Index (VegDRI) and the Quick Drought Response Index (QuickDRI)—were...

A report on the status of America’s forests and rangelands provides a baseline for monitoring future change and its effect on ecosystem services and livelihoods.

Expanding populations, increased urbanization, land use change, and climate change continue to affect American forests and rangelands. Climate change and natural disturbances will alter forest and rangeland ecosystems and affect their ability to provide ecosystem services such as water quality protection, removal of pollutants from the atmosphere, and outdoor recreation. The most recent...

USGCRP co-led an international group of funders and implementers in initiating development of a collaborative research action.

The Belmont Forum is an international partnership between national research funding agencies and international science organizations focused on advancing transdisciplinary global change science and accelerating its application. Its Collaborative Research Actions (CRAs) combine natural science, social science, and stakeholder perspectives to produce knowledge for understanding and responding to global environmental change. In November...

Studying Northern-Ecosystem Response to a Changing Climate

Northern peatlands contain vast organic carbon stocks in danger of release into the atmosphere as greenhouse gases as the climate warms, leading to a positive-feedback cycle of further warming and carbon release. Through field experiments in a Minnesota peat bog, DOE’s Oak Ridge National Laboratory, the USDA Forest Service (USDA-FS), and EPA are collaborating alongside university partners to test how peatland ecosystems respond to conditions that simulate the atmosphere of the future, and improve the ability to predict the release of stored carbon and its impact on climate warming. The...

Building Regional Collaboration for Drought Resilience

In 2015, drought impacts in the Western United States cost an estimated $4.5 billion. Impacts included the fallowing of hundreds of thousands of acres of farmland, excess groundwater pumping, and the exacerbation of wildfire conditions, which contributed to fires that caused the highest annual total of U.S. acreage burned since record-keeping began in 1960. As these impacts become more prevalent under a changing climate, preparedness, including an early-warning system for drought conditions, is increasingly important in many parts of the United States. The...
