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.

Using 29 years of data from Landsat satellites, researchers at NASA found extensive greening in the vegetation across Alaska and Canada.

Scientists are using satellites to collect detailed data on forest change in remote parts of Alaska and the Arctic.

Rapid warming in the Arctic and boreal regions of Alaska is affecting boreal forests and tundra ecosystems in a number of ways. Higher temperatures and changes in precipitation have led to a higher incidence of wildfire and increased tree mortality from drought, insects, and disease. Increases in the length of the growing season and the amount of energy produced by vegetation have also been observed. While tracking how climate...

Mangrove forests store large amounts of carbon, protect the coastline from erosion, and provide shelter for many species.

A new research network aims to accelerate discoveries in the science of these important natural carbon sources and sinks.

Coastal wetlands provide protection from wind and waves, support habitats and fisheries, and store large amounts of atmospheric carbon dioxide for centuries to millennia. These ecosystems can also be sources of greenhouse gas emissions to the atmosphere; wetlands that do not have the capacity to keep pace with sea-level rise, for example, can erode and release soil carbon rapidly to the atmosphere. Freshwater and brackish wetlands also emit methane, a...

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...

Interagency collaboration supported rapid response efforts.

Periods of heavy rainfall caused extensive flooding across much of the Midwestern United States and Mississippi River Basin in spring 2017, including widespread accumulation of 7–10 inches of rain, flash floods, and long-term river flooding. In response, NASA’s Earth Science Disasters Program assembled a team of scientists at NASA’s Marshall Space Flight Center in Huntsville, Alabama, other NASA centers, and NASA-affiliated partners to assist the U.S. Federal Emergency Management Agency (FEMA) and the U.S. National...

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...
