Six Degrees: Our future on a hotter planet – Mark Lynas ****

This is an important book. Books about the horrors of global warming are sometimes referred to as climate change pornography, because they titillate with the frisson of fear about what is going to happen to us – I don’t agree with this label, but if it existed, this would be hardcore.
Mark Lynas describes simply and graphically what would happen if the Earth went through one degree (Celsius) of warming, two degrees, three degrees and so on, through to six degrees. Basing all his predictions on different scientific studies, he explains ruthlessly what will happen to different parts of the world as ice melts, seas rise, temperatures climb and rainfall dries up in some places and becomes torrential elsewhere. This is important, because the temperature rises of themselves don’t sound particularly frightening. We are all familiar what happens when the temperature rises locally by a few degrees – it’s a nice sunny day. We have a lovely time. Yet if Lynas is right, with five degrees we will be looking at billions dying, and with six degrees we will be close to the end of humanity. This is because average temperature rise is only a limited reflection of the massive impact in different areas. Imagine, for instance, practically all of Africa being uninhabitable, with the population of the African countries all heading for a Europe already suffering badly from climate change as refugees.
I have seen it said by another writer on the topic, Fred Pearce, that unless a book tells you how to prevent climate change as well as what the impact will be, it isn’t doing its job. I think he’s wrong. There are plenty of books on making a difference – it’s essential we get more on the impact to drive it home. The only place Lynas is a little iffy is that he does stray into coping with the impact of climate change, basically saying that come 5 degrees or so, there’s no point going all survivalist, it will just get you killed. This is probably true, but overlooks the fact that we need to be able to deal with the lesser, temporary impact of existing climate change – for example, temporary flooding – which is why I think books like my own Global Warming Survival Kit are an important accompaniment to a book like this.
So if it’s so important (and even won the prestigious Royal Society prize for science writing), why only four stars? Because it isn’t the best of reads as a popular science book. Not because of the uncomfortable message, but the approach inevitably means a slightly repetitious format, and despite Lynas’ efforts to bring in some human interest by mentioning specific places he has visited, after a while, the onslaught of this drought and that flood and so on becomes a bit wearing and tempts you to skip. It’s still very important – just doesn’t quite hit the spot as a great popular science read.

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Language of Mathematics - Raúl Rojas ***

One of the biggest developments in the history of maths was moving from describing relationships and functions with words to using symbols. This interesting little book traces the origins of a whole range of symbols from those familiar to all, to the more obscure squiggles used in logic and elsewhere. On the whole Raúl Rojas does a good job of filling in some historical detail, if in what is generally a fairly dry fashion. We get to trace what was often a bumpy path as different symbols were employed (particularly, for example, for division and multiplication, where several still remain in use), but usually, gradually, standards were adopted. This feels better as a reference, to dip into if you want to find out about a specific symbol, rather than an interesting end to end read. Rojas tells us the sections are designed to be read in any order, which means that there is some overlap of text - it feels more like a collection of short essays or blog posts that he couldn't be bothered ...

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 ...
