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.

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...

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...

Modeling efforts provide new data on the effects of climate change in Antarctica.

Between 1998 and 2016, warming in Antarctica has been rapid and significant. Recent observations also reveal increases in snowfall in western Queen Maud Land, East Antarctica that are unprecedented over the past two millennia. To investigate these changes, a team of NSF-sponsored researchers and NASA scientists merged observation-based NSF-funded research with global modeling efforts that benefited from NASA satellite and airborne-based data^[1]...

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...

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...

Interagency efforts are engaging citizens in forecasting and observation of mosquito threats.

Global Learning and Observations to Benefit the Environment (GLOBE) is an international science and education program that provides students and the public worldwide with the opportunity to participate in data collection and the scientific process and contribute meaningfully to our understanding of the Earth system and global environment. In 2017, the U.S. Department of State (DOS) partnered with NASA to leverage GLOBE in engaging hard-to-reach populations in...

Atmospheric composition and circulation over the tropical western Pacific Ocean play important roles in the Earth’s climate system. In this remote region, rising air heated by some of the warmest seawater in the world moves gases produced by ocean organisms and other chemicals to higher altitudes, where water vapor and ozone exert their strongest influence on the climate. As the climate warms, the intensity of this transport mechanism will increase and may contribute to large-scale changes in atmospheric composition. Details of these dynamics, including how they vary over time and space,...

Over the Great Plains region of the United States, summertime thunderstorms often occur after sunset. Much of this nighttime rainfall is caused by large, organized storm systems and plays a critical role in the hydrology and agriculture of the region, especially over the more arid western Great Plains. During the summer months, these nighttime storm systems provide 30-70% of the region’s precipitation and can also cause severe weather, including flash floods, intense damaging winds, and large hail. Current weather and climate models have difficulty predicting the onset, location, frequency...

As of 2010, urban areas are home to more than half of the world's population, produce at least 70% of carbon-dioxide emissions from fossil fuels, and emit a significant amount of anthropogenic methane, but represent a small fraction of the Earth’s land surface. Currently, greenhouse gas emissions estimates for many cities are either unavailable or are generated using self-reported data from particular sectors, and contain significant uncertainties. Although methods for comprehensive measurement of urban emissions have been tested in smaller cities with stable emissions, these techniques...
