Not so long ago, the idea that giant reptiles once roamed the earth was novel, unbelievable to some, but their reign represents only one part of deep time. Go back further in time, to the Carboniferous (358.9 to 298.9 million years ago), and you will find a world of giants as bizarre and otherworldly as the dinosaurs must have once seemed to us. A world where clubmoss trees grew up to 50 metres tall, with scorpions as large as dogs and flying insects the size of seagulls. With Carboniferous Giants and Mass Extinction, palaeobiologist George McGhee, Jr. presents a scholarly but fascinating overview of the rise and fall of this lost world, and why it still matters to us.
“It is worse, much worse, thank you think”. With these ominous words, David Wallace-Wells, deputy editor at New York magazine, starts his no-holds-barred story of climate catastrophe. Pulling together worst-case scenario predictions, he is hell-bent on scaring the living daylight out of his readers by sketching the manifold crises that loom in our near future if we let climate change develop unchecked. He proves a poetic agitator and I admire his outspokenness – I don’t think he is alarmist, but simply saying what many scientist are silently thinking. Whether this divisive approach is helpful is another question, and one for which he has been criticised. It is a price Wallace-Wells is willing to pay, because he thinks most people are not scared enough.
Like so many teenagers, I wanted to become a palaeontologist. However, there was no degree programme in palaeontology in the Netherlands back then (I doubt there is one nowadays), so I was advised that one option to prepare myself was to do a Master’s in biology or geology. I choose the former and never looked back, but remained fascinated with the latter. Now, twenty years later, my job exposes me to many geology textbooks and especially Cambridge University Press has a wonderful output of advanced-level books that I really want to read. But when I reviewed Earth History and Palaeogeography some time ago, I realised I was out of my depth and struggled with the jargon. Is it ever too late to start over and make an entry into a new field? I decided to shell out and invest in a textbook to find out.
When a history book leaves you reeling, you know that it has done its job properly. Climate Change and the Health of Nations is a grand synthesis of environmental history, charting the fate of civilizations and the links between climatic changes and the health of people. It is also a book that almost wasn’t.
Krill is one of those enigmatic invertebrate groups that feeds whole ocean ecosystems but remains itself little known. Even to a biologist such as myself (who has studied fish for crying out loud!), these critters are largely a set of question marks. I mean they are crustaceans, swim in the sea, are numerous and… oh look, a blue whale!
At first blush, you might think this book is part of the ongoing craze of spiritual mindfulness books. But let me refrain from snarky comments. Geologist Marcia Bjornerud does indeed want to instill a sense of mindfulness about deep time, but one that is, pardon the pun, grounded in geology. In her opinion, most of us lack an awareness of durations of important chapters in our planet’s history and of rates of change of many natural processes. As a consequence, we fail to see just how rapidly we are altering our planet. In one of the first paragraphs she eloquently writes:
“Like inexperienced but overconfident drivers, we accelerate into landscapes and ecosystems with no sense of their long-established traffic patterns, and then react with surprise and indignation when we face the penalties for ignoring natural laws”.
And with that, she had me hooked.
So, stop me if you’ve heard this one before, but it is often said that we know more about the moon than we do about our own oceans. However, palaeo-oceanographer and climate scientist Eelco J. Rohling points out we know more than you might think. His new book, The Oceans: A Deep History, takes the reader through a 4.4-billion-year history of Earth’s oceans. Much more than just a book about water, this is foremost a book about the intimate link between our planet’s climate and its oceans, as they are far more intertwined than you might give them credit for.
