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.
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.
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.
You might think that with the constant presence of the subject of climate change in news stories there isn’t much left to tell. But just because a certain sense of climate-change-fatigue might have set in (which is worrying in itself), climate change has not stopped. In Brave New Arctic, geography professor Mark C. Serreze gives an eye-witness account of how the Arctic is rapidly changing, based on his more than 35 years of personal involvement. And as he shows, there certainly are stories left to tell.
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.
