Summary

Story summary

Scientists are harnessing the power of trees to detect volcanic activity by tracking shifts in vegetation around volcanoes. As magma ascends, trees absorb more carbon dioxide, resulting in a greener appearance visible from space. This innovative approach strengthens early warning systems, enabling swift evacuations, with NASA and the Smithsonian Institute working together to enhance monitoring in vulnerable regions like Hawaii and Alaska.
