Atmosphere of Hope - Tim Flannery *****

With the Paris summit on climate change just concluded, it's hard to imagine a better time for a new book on the subject, and the subtitle of Tim Flannery's chunky little volume is very encouraging: 'solutions to the climate crisis.' In fact it is just as well he is offering solutions. Not only are the shelves pretty full of titles telling how terrible the impact of climate change is going to be, but (misery memoirs apart) there is quite a strong feeling that doom and gloom books don't sell.

It's not that Flannery begins in cheerful mood. He takes us through the increasingly indisputable evidence that climate change is not just happening but is already having impact on everyday lives, from bush fires in Australia to flooding in the UK. After presenting a picture of increasingly disastrous implications if we choose to carry on as normal, Flannery takes us through the various key means of producing energy, their impact on the climate and where we need to be concentrating. It's fascinating that after concerns in the past about running out of fossil fuels, Flannery thinks that before long we will be moving away from them with plenty left, as the money is divested from the industry. 

When it comes to what replaces fossil fuels, he is hugely enthusiastic about wind and solar and brushes aside concerns about their limited availability (e.g. solar at night or in a UK winter) without giving a clear picture of how the balance will be maintained. He is also dismissive of nuclear, in an argument that seems more emotional than logical. One of the most interesting aspects of this section is his admission that in his previous bestselling book, published 10 years ago, he pretty much ignored electric cars, assuming that hydrogen etc. would be the preferred solution, but now he is (sensibly) wholeheartedly behind them. 

We then move onto solutions. Flannery is rightly suspicious of the kind of geoengineering that fights fire with fire, for instance seeding the stratosphere with sulfur to mimic the cooling effect of a massive volcanic eruption. But he is very positive about various techniques to take carbon out of the atmosphere (though oddly dismissive of the low hanging fruit contributed of taking carbon dioxide from power station exhausts). He also claims that where once all we could do as individuals was wait for the politicians or dabble with low energy lightbulbs, now we can do much more. However, apart from fitting solar panels (not an option for many of us), this 'action' seems to be limited to joining activist groups, which may be more likely to generate hot air than reduce carbon emissions.

There's much that I really like about this book, and I will be giving my copy to a climate change sceptic friend in the hope of converting him.  However, there are some issues. Flannery spends far too much time telling us how important he is and how influential his last book was. This kind of validation of the author is useful in the blurb, but in the content of the book it comes across as irritatingly self-serving. The book is also very Australia/US centric. I suppose I shouldn't complain, since many books by UK authors pretty much ignore Australia, but given this is a UK edition from a UK publisher, the examples could have been tweaked to better fit the market. And the last part of the book is definitely a let down, when we are promised things we can do as individuals and just get 'join a pressure group.'

However, my niggles don't prevent this being an important and thoughtful book, giving up-to-the-minute analysis of our climate situation and what can be done about it. I hope Nigella will be buying a copy for her dad.

Lucy Jane Santos - Four Way Interview

Lucy Jane Santos is an expert in the history of 20th century leisure, health and beauty, with a particular interest in (some might say obsession with) the cultural history of radioactivity. Writes & talks (a lot) about cocktails and radium. Her debut book Half Lives: The Unlikely History of Radium was published by Icon Books in July 2020.

Why science?

I have always been fascinated by the idea of science especially our daily interactions with and understandings of science – especially in a beauty context. I could spend hours pondering the labels of things on my bathroom shelf. What is 4-t-butylcyclohexanol (as a random example)? Do I really understand what I am putting on my face and spending my money on? Would it change my purchase habits if I did?  

Why this book?

This book came from an accidental discovery – that there was a product called Tho Radia which contained radium and thorium. I found out about it because I actually bought a pot of it – along with a big batch of other produc…

Rewilding: Paul Jepson and Cain Blythe ****

Those who are enthusiastic about saving the environment often have a mixed relationship with science. They might for example, support organic farming or oppose nuclear power, despite organics having no nutritional benefit and requiring far more land to be used to raise the same amount of crops, while nuclear is a green energy source that should be seen as an essential support to renewables. This same confusion can extend to the concept of rewilding, which is one reason that the subtitle of this book uses the word 'radical'.

As Paul Jepson and Cain Blythe make clear, though, radical change is what is required if we are to encourage ecological recovery. To begin with, we need to provide environments for nature that take in the big picture - thinking not just of individual nature reserves but, for example, of corridors that link areas allowing safe species migration. And we also need to move away from an arbitrary approach to restricting to 'native' species, as sometimes…

Is Einstein Still Right? - Clifford Will and Nicolas Yunes ***

If there's one thing that gets a touch tedious in science reporting it's the news headlines that some new observation or experiment 'proves Einstein right' - as if we're still not sure about relativity. At first glance that's what this book does too, but in reality Clifford Will and Nicolas Yunes are celebrating the effectiveness of the general theory of relativity, while being conscious that there may still be situations where, for whatever reason, the general theory is not sufficient.

It's a genuinely interesting book - what Will and Yunes do is take experiments that are probably familiar to the regular popular science reader already and expand on the simplified view of them we are usually given. So, for example, one of the first things they mention is the tower experiments to show the effect of gravitational red shift. I was aware of these experiments, but what we get here goes beyond the basics of the conceptual experiment to deal with the realities of d…
