Extraction to Extinction - David Howe ****

In this book, David Howe manages the near-impossible - making geology interesting. Usually, this is one of those dull, earnest sciences that it's hard to get too excited about. It might be a slight exaggeration, but for many of us, when you've seen one rock, you've seen them all. But Howe overcomes this issue with a combination of engaging storytelling and combining information about geology with how we humans have made use of them and the materials made from them - the book absolutely comes alive whenever we move from how the rocks were formed to how they have been used (and abused).

That storytelling element captured me from the first sentence: Howe had me at 'I was standing on Alderley Edge when I first wondered about it.' I admit that this is partly a matter of personal identification with the story. I too went to school in Manchester and explored Alderley Edge as a teen - I was a fan of Alan Garner, and even (not entirely licitly) ventured down the copper mines that Howe describes.

As far as the applications side goes, we tend to take for granted the availability of the raw materials extracted from the Earth that go to make up familiar objects, but as Howe takes us through the origin stories of brick and ceramics, copper, iron and steel, concrete, glass, aluminium, plastics and lithium and the rare earth elements, he both makes these everyday objects appear far more special and puts them into their context in the bigger picture of nature.

We then get the least satisfactory part of the book, where Howe takes us through the downside of our overuse of the Earth's resources and of the pollution and greenhouse gas production that results. It's not that these are unimportant issues, but they need a book in their own right to be as nuanced as the rest of the contents - having a couple of chapters on the subject just takes away from the rest of the book without being able to explore the issues properly. (There is, for example, no real mention of the need to balance out inconsistent sources like wind and sun, particularly somewhere like the UK, with storage and, almost certainly, nuclear.)

Things pick up again with the final chapter on the debated topic of whether we are now in the 'Anthropocene' epoch, where the reader is presented with the beguiling concept of future geologists finding layers in the Earth that correspond to what humans are doing at the moment. The only opportunity potentially missed here was to open up the debate as to whether this is a true epoch or a geological event.

Every now and then, usually when trying to be humorous, Howe's writing style becomes rather old fashioned - for example 'There appears to be a population of bevvy-swilling bozos who, wishing to show their strength by crushing flat their drained cans and then tossing them out of their car windows lend support to the Yorkshire proverb "Strong int'arm and thick in't head"' - but mostly I found this an enjoyable and thought-provoking read.

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

Pagans (SF) - James Alistair Henry *****

There's a fascinating sub-genre of science fiction known as alternate history. The idea is that at some point in the past, history diverged from reality, resulting in a different present. Perhaps the most acclaimed of these books is Kingsley Amis's The Alteration , set in a modern England where there had not been a reformation - but James Alistair Henry arguably does even better by giving us a present where Britain is a third world country, still divided between Celts in the west and Saxons in the East. Neither the Normans nor Christianity have any significant impact. In itself this is a clever idea, but what makes it absolutely excellent is mixing in a police procedural murder mystery, where the investigation is being undertaken by a Celtic DI, Drustan, who has to work in London alongside Aedith, a Saxon reeve of equivalent rank, who also happens to be daughter of the Earl of Mercia. While you could argue about a few historical aspects, it's effectively done and has a plot...

Amazing Worlds of Science Fiction and Science Fact: Keith Cooper ****

There's something appealing (for a reader like me) about a book that brings together science fiction and science fact. I had assumed that the 'Amazing Worlds' part of the title suggested a general overview of the interaction between the two, but Keith Cooper is being literal. This is an examination of exoplanets (planets that orbit a different star to the Sun) as pictured in science fiction and in our best current science, bearing in mind this is a field that is still in the early phases of development. It becomes obvious early on that Cooper, who is a science journalist in his day job, knows his stuff on the fiction side as well as the current science. Of course he brings in the well-known TV and movie tropes (we get a huge amount on Star Trek ), not to mention the likes of Dune, but his coverage of written science fiction goes into much wider picture. He also has consulted some well-known contemporary SF writers such as Alastair Reynolds and Paul McAuley, not just scient...
