Leaving NOLA for an early departure from #AGU25. I feel so lucky to work with amazingly kind and generous people from all over the world. I am particularly inspired by passion and creativity of the students I met. Certainly feel like my hope in the future has been rekindled 🌋

🌋🧪 #ScienceAdventCalendar Day 6 (yes, I've already fallen behind...) Volcanoes produce a LOT of gas, but still only ~1% of the CO2 amount produced by human activity. Even the biggest modern eruptions come nowhere near close! Handy article about volcanoes and climate: www.usgs.gov/programs/VHP...
