Arctic Tundras Turning Greener as Global Temperatures Rise, NASA Study Finds
Warming Summers Driving Changes in Northern Landscapes
Using data from NASA's Ice Cloud and land Elevation Satellite 2 (ICESat-2) and Landsat, researchers have found that rising global temperatures are turning the Arctic tundras green, indicating a change in vegetation.
Concomitant Changes Observed
As tundra ecosystems experience rising temperatures, researchers observed concomitant changes in vegetation, such as increased growth and altered species composition, which contribute to the greening of the landscape.
2022 Greenness Patterns
Tundra greenness in 2022 was unusually high in most of the North American Arctic, except for some areas in Alaska where unusually low greenness was observed. These patterns are linked to variations in temperature and precipitation.
Automated Sensors Installed
In June 2022, researchers installed automated sensors in the Arctic to capture springtime conditions and monitor the ongoing changes in vegetation and other ecosystem components.
