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.

Detecting the drivers of forest change in Alaska and the Arctic

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...
