Here is a story on a topic you don’t read about every day. A new study done in collaboration between NASA and the Smithsonian shows that satellites may be able to help identify volcanoes that are about to erupt by looking for signs of enhanced carbon dioxide emissions in plant life downwind of the volcano. The idea is that a volcano that is about to erupt may start emitting more gases to the atmosphere in advance of an active eruption and those gases, which include carbon dioxide, may turn the plants in the gas plume greener than surrounding plants due to the enhanced CO2. This intensified greenness could be identified from space through satellite scans. This could be useful in providing an advance warning of an impending eruption, something that is hard to find.
