An informative excerpt:
"Much of the buoyant CO2 floats to the top of the chamber and leaks out through the roof, escaping to the atmosphere through surface vents and fumaroles-more than 8,000 tonnes each day."
Eight thousand ton(nes) per day of CO2.
To frost the cake, the, obviously, British, author wrote "tonnes", which, we think, means that it's ten percent more than would be indicated by our own "tons".
Wonder how many similar volcanoes there are in the world? We're checking.
Or, would everyone just rather puff some powder over that pimple on the CTL elephant's butt, and get on with it?
