Water Limitations in the Tropics Offset Carbon Uptake from Arctic Greening

Water Limitations in the Tropics Offset Carbon Uptake from Arctic Greening

As Earth's climate is changing, increased uptake of atmospheric carbon by plants in the Arctic is being offset by a corresponding decline in the tropics. GMAO contributed to a study of ongoing productivity patterns across the globe. See the NASA GSFC press release for more information.
