Book review – Earth Wars: The Battle for Global Resources

7-minute read

When it comes to environmental issues, certain topics steal the limelight, with climate change, deforestation, and biodiversity loss being prominent examples. However, humans have only so much time and energy available, meaning that other, potentially more pressing problems might not get the attention they deserve. Resource depletion, specifically all the materials we dig up from the Earth’s crust, has always struck me as one of them. It is easy to underestimate just how thoroughly dependent modern civilization is on a vast range of very basic substances. As we continue to extract these at ever-accelerating rates, competition and conflict seem inevitable. Guessing by the title of this book, Australian business journalist Geoff Hiscock seems to think so too. Yet this book was not quite what I was expecting.

Book review – Volcanotectonics: Understanding the Structure, Deformation and Dynamics of Volcanoes

7-minute read

We all have a pretty good idea of what a volcanic eruption looks like, but they are only the surface expression of a much larger and longer underground process that is hidden from view. The internal workings of a volcano, its plumbing if you will, are studied by the relatively new scientific discipline of volcanotectonics. Icelandic volcanologist Agust Gudmundsson has been researching and teaching this topic for two decades and here delivers the field’s first textbook. In preparation, I beefed up my knowledge base by first reviewing a introductory volcanology textbook, but it almost was not necessary – Volcanotectonics turned out to be exceptionally instructive and accessible.
