On 22 May 2025 SciTechDaily reported: Trees near volcanoes might be the early warning signs scientists have been looking for -- and now, they can be watched from space. A NASA-Smithsonian collaboration has revealed that carbon dioxide released from rising magma makes surrounding vegetation greener, a subtle but trackable signal. Using satellite imagery and ground validation, researchers are crafting a powerful new way to detect volcanic unrest before it erupts into disaster, potentially saving thousands of lives. Global Good News service views this news as a sign of rising positivity in the field of science, documenting the growth of life-supporting, evolutionary trends.

It turns out that trees can help warn us when a volcano is getting ready to erupt. Scientists have long known that changes in tree leaves, like becoming greener or more lush, can signal volcanic activity nearby. Now, thanks to an exciting collaboration between NASA and the Smithsonian Institution, researchers believe they can spot these changes from space.

...Using satellites to monitor trees around volcanoes would give scientists earlier insights into more volcanoes and offer earlier warnings of future eruptions. 'There's not one signal from volcanoes that's a silver bullet,' Schwandner said. 'And tracking the effects of volcanic carbon dioxide on trees will not be a silver bullet. But it will be something that could change the game.'
