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.
An observing campaign on the West Antarctic Ice Sheet is improving understanding of influences on recent ice loss and the implications for future sea level rise.
Antarctica holds the largest reservoir of ice on Earth and is significant contributor to sea level rise. The West Antarctic Ice Sheet, once considered relatively stable, has shed an increasing amount of ice...
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...
