Volcanoes and CO2 – continued

In the first part of this post, we looked at magical carbon and where to find it. We now continue to look at how much CO2 volcanoes produce, and how it compares to our own emissions. Who wins the battle? The results of the polls are: A small majority believes that volcanoes produce less CO2…

Volcanoes and CO2

The world we live in has a volcanic history. The continents ultimately came from volcanoes, often volcanic arcs, in some cases several billions of years ago, in other cases more recently. All ocean floor is volcanic, made in mid-oceanic rifts within the past few hundred million years. And the volcanic contributions do not stop there.…

If everything was known about every volcano, identifying and motivating the choice of the ten most dangerous ones would be a relatively simple matter. As it is, our selections have to be based on what meagre…
