Hashem Al-Ghaili on Instagram: "🚨 Trees around volcanoes can act as communication systems, warning of imminent eruptions. Scientists have discovered that trees absorb extra carbon dioxide released by magma underground before an eruption, supercharging their photosynthesis and subtly altering how their leaves reflect light. These changes, invisible to the human eye, are detectable from space using satellites like NASA’s Landsat 8 and ESA’s Sentinel-2. A joint NASA-Smithsonian study confirmed the connection by tracking leaf color shifts alongside volcanic CO₂ levels in Chile and Costa Rica. With around 10% of the global population living near active volcanoes—many in remote areas—this breakthrough could significantly enhance eruption forecasting. While not foolproof (some volcanoes lack vegetation, and climate affects plant responses), this method adds a crucial layer to existing monitoring systems. By using trees as indicators and satellites as observers, scientists gain a powerful new tool to detect signs of volcanic unrest from orbit, potentially saving lives with earlier warnings. learn more https://www.nasa.gov/earth/natural-disasters/volcanoes/nasa-satellites-provide-early-volcano-warnings/"
