...a rather interesting finding:

https://wattsupwiththat.com/2025/05/19/volcanoes-s...

Manchester’s Volcanic CO2 Bombshell might be a game changer. The Manchester team, led by Alexander Riddell, deployed cutting-edge sensors on a helicopter to measure emissions from the Soufrière Hills Volcano in Montserrat. Published in Science Advances DOI: 10.1126/sciadv.ads8864, their findings are a wake-up call. Traditional monitoring focused on hot volcanic vents (fumaroles) that spew easily detectable gases like sulfur dioxide (SO2). But cooler, water-rich hydrothermal systems absorb acidic gases, masking significant CO2 output. The new tech revealed that Soufrière Hills emits three times more CO2 than earlier estimates suggested.

Riddell notes, “Volcanoes play a crucial role in the Earth’s carbon cycle,” but he’s quick to downplay the impact, claiming volcanoes contribute less than 5% of global CO2 compared to human activities like fossil fuel burning. Fair enough, but if one volcano’s emissions are underestimated by a factor of three, what about the thousands of others worldwide? The study hints at a broader issue: our volcanic CO2 estimates could be way off, especially for volcanoes with similar hydrothermal systems.

Here’s where it gets spicy. The climate establishment loves to pin the rise in atmospheric CO2—now around 420 ppm—squarely on human emissions. But these two studies, released within weeks of each other, expose massive gaps in our understanding of natural CO2 sources. If volcanic emissions on land are triple what we thought, and we’ve just found 19,000+ new undersea volcanoes, the natural contribution to atmospheric CO2 is likely far higher than the “less than 5%” figure tossed around.
