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.

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...

Field research provides new data advancing our ability to project how tropical forests will respond to a changing climate.

Tropical forests store vast amounts of carbon and play a key role in regulating Earth’s climate. As climate changes, these ecosystems have the potential to become a net contributor to global warming if they shift to releasing more carbon to the atmosphere than they absorb^[1]. However, how these forests will be affected by a warming climate and changing atmosphere is still uncertain¾and is critical...

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...

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...

Spatial distribution of A, annual carbon loss and gain across upland Alaska 1950–2009 and B, historical fire scars from 2000–2009 among the five Landscape Conservation Cooperative (LCC) regions.

An assessment of carbon stocks in Alaska’s soils and vegetation helped set a baseline for monitoring future change.

Alaska’s soils and vegetation store vast quantities of carbon. Increases in temperature throughout the 21^st century may increasingly expose these stores to loss from increased wildfire, permafrost thaw, and other changes that could turn Alaska’s ecosystems into a net source of carbon to the atmosphere. However, much of Alaska has previously not been considered in any major national...
