Adventures in the Anthropocene

Science journalist Gaia Vince left her desk at Nature and spent two years visiting places around the world, some of them very isolated, where people were grappling with the conditions of what is sometimes described as a new epoch, the Anthropocene. It dates from the industrial revolution and represents a different world from the relatively settled Holocene in which human civilisation was able to develop. Adventures in the Anthropocene tells the story of Vince’s encounters with some remarkable individuals and their communities. It also includes lengthy musings on the technologies the future may employ as humanity faces the challenges of climate change, ocean acidification, population growth, resource depletion and more.

Vince goes to the front lines of the human battles. In a remote village in Nepal she describes the extraordinary work of Mahabir Pun who gained a university scholarship in the US and returned years later to bring computers and Wi-Fi to the children of his village. It’s a fascinating story, full of hope for development in his region. But it’s also precarious. Electricity for the computers comes from a small hydro-scheme fed by glacier water. In the same chapter Vince points out that the warming rate in that Himalayan region is five times greater than the global average and the glaciers are melting. Once they are gone there is no meltwater and no power. Levels have already been diminishing in the once-deep stream near the village.

Antarctica: An Intimate Portrait of a Mysterious Continent

Science journalist Gabrielle Walker’s book Antarctica: An Intimate Portrait of a Mysterious Continent (Bloomsbury, 2012) tells an absorbing story of the wide variety of scientific work undertaken in Antarctica and the support services that maintain it. It also attempts to capture the human fascination of the continent, not least for the author herself in her five sojourns there. She provides close-up observations of some of the specialist teams working on an array of investigations: penguins, seals, under-ice sea creatures, meteorites, astronomy, paleoclimatology, the dynamics of ice movement and loss, and more. Stories of the early explorers find a place, and the psychology which motivates people to undertake sometimes long scientific enterprises in such a demanding environment.   Her book is striking and highly readable, often gripping.

It’s the climate change aspects of the book that I want to highlight here. Walker, who has a strong academic science background, specialises in energy and climate change. She co-authored a book on climate change with Sir David King a few years ago. I reviewed it at the time. Her knowledgeable familiarity with the subject is often in evidence in Antarctica.

The Collapse of Western Civilization: A View From The Future

Science historians Naomi Oreskes and Erik Conway, co-authors of the acclaimed Merchants of Doubt, have joined forces again to produce a striking short fictional work The Collapse Of Western Civilization: A view From The Future. It purports to be an essay written by a Chinese historian three hundred years after the collapse of western civilisation towards the end of the 21st century when untrammelled climate change took its full effect.

The period of the Penumbra (1988-2093) ended in the Great Collapse and Mass Migration (2073-2093). That’s the scope of our Chinese historian’s survey. He (or she)records the dawning scientific realisation of the effects human activities were having on the planetary climate, the setting up of the Intergovernmental Panel on Climate Change and the first manifestations of the change in the intensification of fires, floods, hurricanes, and heat waves. Thus far he writes of matters familiar to us.

He then moves on to recount the rapidly mounting disasters as the century proceeds. It’s somewhat unnerving to read of what we know as predictions as if they had already become the stuff of history. All the more unsettling because anyone who follows climate science will recognise that the chain of disaster he traces, from failing food crops in intense heat waves to unmanageable sea level rise as the West Antarctic and Greenland ice sheets begin to disintegrate is entirely possible if greenhouse gases continue to be pumped into the atmosphere by human activity. The resultant human suffering and death the historian records may be more speculative from our end, but his calm account of the human consequences has a dismaying ring of likelihood to it.

The Sixth Extinction

Elizabeth Kolbert’s recent book The Sixth Extinction: An Unnatural History is science journalism of a high order. As with her earlier notable book on climate change, Field Notes from a Catastrophe, she includes lively narrative accounts of her visits to places around the world where scientists are at work and communicates the import of their work with clarity and intelligence. Well-informed background discussions on the general topic of extinction are woven into these narratives, in passages well pitched to the understanding of the general reader. Foreboding though the subject may be the book is a pleasure to read.

The phenomenon of species extinction has only begun to be understood in relatively recent times. Kolbert traces the discussions of the 19th century from the ground-breaking conclusion of Cuvier to the doubting Lyell and finally Darwin, whose theory of evolution necessarily involved the disappearance as well as the emergence of species.

In evolutionary terms the mass extinctions of the distant past are a special case, arising from relatively sudden events for which natural selection over long periods of time had not prepared many of the species which disappeared under the stress of a rapidly changed environment. Kolbert comments on the fact that just as we have recovered the story of these past events and identified five of them we have discovered that we are causing another. Whether it will reach the proportions of the Big Five is not yet known, but the indications are significant enough for it to be called the Sixth Extinction. She notes the estimation that one-third of all reef-building corals, a third of all freshwater mollusks, a third of sharks and rays, a quarter of all mammals, a fifth of all reptiles , and a sixth of all birds are headed toward oblivion. It’s no small matter.

Climate Change and the Course of Global History

The title in the Kindle Store was irresistible: Climate Change and the Course of Global History: A Rough Journey. American historian John L Brooke is the author, and the book is notable for its attempt to integrate climate science with the study of human history. In his acknowledgements the author brackets climate scientists with historians and archaeologists in the long list of people with whom he has corresponded and from whom he has received data and an understanding of scientific culture.

The scope of the book is as wide as human emergence in the evolutionary process, and before. It’s not my purpose to track through the long story the author has to tell or to follow the intricacies of the climate shifts he refers to. The book demands and rewards patient reading in these respects. But I offer a few comments arising from my reading of the book.

An historian making the effort to understand climate science as thoroughly as Brooke does seems to me in itself worth remarking. Often I could have been reading one of the many books by scientists or science writers that I’ve reviewed over past years on Hot Topic. The culture gap between the sciences and the humanities that C P Snow’s famous 1959 lecture lamented was certainly not evident in Brooke’s history. Five years ago I reported the plea of biographer Richard Holmes at the Hay Festival that we reject the notion of two cultures and accept the duty to understand the scientific discoveries of the modern age, a duty of crucial importance in the face of global warming. Brooke has clearly accepted that duty, though I fear many educated in the humanities continue to excuse themselves from it.
