Hurricane Lizards and Plastic Squid - Thor Hanson ****

There have been many books on climate change, but Thor Hanson's quirkily titled contribution takes quite a different tack - it's about the impact climate change has on species and how they respond through moving, adapting, evolving or clinging on to a remnant of their original habitat.

This could have been a dull and worthy catalogue of doom, but Hanson's personal and chatty approach gives us a more balanced insight - sometimes it's a relatively good news story, though there is no doubt that remarkably small changes in climate can have a noticeable effect on the local flora and fauna, and in some cases, with nowhere to go and limited ability to adapt. this will lead to species being wiped out. 

The impact of climate change is illustrated through a whole host of different species. We meet marmot-like pikas and Joshua trees, dovekies and anole lizards (the 'hurricane lizards' of the title, which feature in a bizarre experiment involving a leaf blower to test how they cope with different wind strengths) and even strange locations that are able to maintain a colder climate than their surroundings, producing pockets of flora and fauna that haven't moved in response to a temperature rise.

Along the way there are plenty of personal stories, from fishing trips to experiments with his son on the impact of carbon dioxide, plus a couple of particularly impressive examples of situations where a scientist has set out to study a particular animal or plant behaviour with no consideration of the climate, only to have climate change forcefully take over the study, producing data on a totally different issue. Keeping the reader on side is one of Hanson's strong points. Just occasionally he tries a bit too hard - there's an occasion where he takes a whole page of text just to tell us that trees don't move in the normal sense, invoking everything from Birnam Wood to ents - but generally there is plenty to carry the reader along.

Although Hanson suffers a little from scientists' blinkers - in, for example, continuing to fly around the world, or in his contorted defence of his son's enthusiasm for an old petrol-hungry tractor - there is a more balanced realism here than is often seen in climate change polemics. This accompanies the reality that there have been plenty of examples of climate change in the past which have also had huge impacts on species distribution or extinction. Hanson recognises that we can't preserve things as they are in aspic - but equally makes clear just how complex the interplay of species is, so that the movement of a species that seems to have no obvious impact can, through the chain of interaction with other species around it, result in radical shifts that have impact on many other species, including humans.

An enjoyable, thought provoking book.

We Are Eating the Earth - Michael Grunwald *****

If I'm honest, I assumed this would be another 'oh dear, we're horrible people who are terrible to the environment', worthily dull title - so I was surprised to be gripped from early on. The subject of the first chunk of the book is one man, Tim Searchinger's fight to take on the bizarrely unscientific assumption that held sway that making ethanol from corn, or burning wood chips instead of coal, was good for the environment. The problem with this fallacy, which seemed to have taken in the US governments, the EU, the UK and more was the assumption that (apart from carbon emitted in production) using these 'grown' fuels was carbon neutral, because the carbon came out of the air. The trouble is, this totally ignores that using land to grow fuel means either displacing land used to grow food, or displacing land that had trees, grass or other growing stuff on it. The outcome is that when we use 'E10' petrol (with 10% ethanol), or electricity produced by ...

Battle of the Big Bang - Niayesh Afshordi and Phil Harper *****

It's popular science Jim, but not as we know it. There have been plenty of popular science books about the big bang and the origins of the universe (including my own Before the Big Bang ) but this is unique. In part this is because it's bang up to date (so to speak), but more so because rather than present the theories in an approachable fashion, the book dives into the (sometimes extremely heated) disputed debates between theoreticians. It's still popular science as there's no maths, but it gives a real insight into the alternative viewpoints and depth of feeling. We begin with a rapid dash through the history of cosmological ideas, passing rapidly through the steady state/big bang debate (though not covering Hoyle's modified steady state that dealt with the 'early universe' issues), then slow down as we get into the various possibilities that would emerge once inflation arrived on the scene (including, of course, the theories that do away with inflation). ...

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...
