Origins asks one question: how did the Earth make us? More accurately, like a six-year-old whose curiosity cannot be sated, there lies a series of recursive “why” questions at the heart of this book. Astrobiologist and science communicator Lewis Dartnell takes a big history look at human evolution and especially civilization, seeing how far down the explanatory rabbit hole he can go. Time and again, he grounds his answers in geology and geography. You would be forgiven for thinking this sounds like what Jared Diamond attempted more than two decades ago, but calling it Diamond-redux would not do it justice.
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.
Somewhere in chapter 2, Kyle Harper remarks how historians have become unintentional beneficiaries of ongoing climate change, as scientists turn to palaeoclimatic records such as ice cores, tree rings, and sediments to understand fluctuations in earth’s climate. This bonanza of data allows historians a new way to look at past events. And thus was born the discipline of environmental history, which emphasizes the active role the natural environment can have on human affairs. In The Fate of Rome, Kyle Harper looks at one of those defining moments in human history, the decline and fall of the Roman empire, and the role of climate change and pandemics.
