🌋🧪 #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!

🌋🧪 #ScienceAdventCalendar Day 5!

Let's talk about the OTHER polar #volcano - Mt Erebus in #Antarctica. This 🌋 is one of only a few worldwide with an active lava lake in its crater! Technically NOT on Antarctica (Ross Island), this is the southernmost active volcano in the world

🌋 🧪 #ScienceAdventCalendar Day 4!

Did you know that Norway has its own active 🌋? Beerenberg volcano, on Jan Mayen island in the Arctic Ocean, last erupted in the 1980s. There is no permanent population on the island and is the world's most northern active volcano on land!

🌋 #ScienceAdventCalendar Day 3!

The big picture: There are thought to be ~1300 "active" volcanoes around the world. This accounts for any volcano with a likely eruption over the Holocene - the last 12,000 years.
