The Earth Transformed, Peter Frankopan

 

The Earth Transformed, Peter Frankopan

The Earth Transformed is truly planetary in its scope and ambition. Its 658 pages do not even include introductory material, plates, footnotes or index - come to that, where are the footnotes? Online somewhere? We go back temporally 4.5 billion years to the formation of the earth and forward into the future. We travel upwards and outwards from the earth’s core to ocean depths and land masses, then through the atmosphere to the farthest reaches of the solar system. Even more impressive is the scale of Frankopan’s learning. He has not only mastered the histories of most cultures in most parts of the world, he has also immersed himself in all the latest research on anthropology, biochemistry, climatology, dendrochronology, epidemiology, all the way through to zoology, and goodness knows how many other disciplines besides. 

This exhaustive approach is in the good cause of being able to take a comprehensive overview of the state of our interactions with our home planet. If you have ever bemoaned the fissiparation of knowledge into ever tinier areas of specialism that become more and more remote from one another and from the awareness of ordinary people, fear not! Peter Frankopan is out there: he gets it and is doing something about it. He wants to see how raft after raft of new discoveries stack up together, and thus give a big picture – a Frankopanorama - of what we are doing to the planet and what it is doing to us.

Some of his key findings:

• The earth has always been in a state of flux. Conditions were originally unrecognisably different from anything we experience today and would have been lethal to contemporary life forms. Changes have come in the form of cataclysms: asteroid impacts, massive volcanic events, the collisions of continents, soaring and plummeting temperatures, orbital changes for both the earth and moon… There have been periods of relative stability too, when the various forces that circulate energy round the world have been in balance: but only until the next catastrophe. The idea that the state of the world is pretty much a given, roughly what it is now, is an illusion deriving from our ignorance of the deep past.

• Climate is an important driver of this flux. Frankopan is not in any way a climate change denier. The research he quotes shows a clear correlation between higher levels of carbon dioxide in the atmosphere in the past and raised temperatures, and between lower levels and reduced temperatures. The connection is indisputable. Climate change deniers have to accept that the world’s climate is changing, as the evidence is there: but they attribute this to “natural cycles,” in a naïve way that omits to examine the role that levels of CO2 play in those cycles. Does it matter how the CO2 gets there? It’s still going to warm the planet, however it comes, isn’t it? So stop junking our atmosphere, you oil barons!

• Climate directly impacts human history, including pestilences, famines, migrations, the economy, the winners and losers of political struggles and so on. So for example, a wetter climate across Central Asia allowed the hordes more fodder for their horses and enabled repeated incursions Westward into Europe: a period of stable warmth supported the crops that underpinned Roman prosperity and expansion: rainfall promoted the rise of South American civilisations and droughts led to their fall. However this requires more nuance than Frankopan always gives. Why for example did the Romans succeed in benefitting from the Roman Warm Period in ways that their many rivals, Etruscans, Persians, Carthaginians, Dacians, did not? Was it military might? Or better administration? Or those beautifully engineered aqueducts that enabled the expansion of Roman cities? Or why did a grassier steppe enable the Mongols to spread West, but did not lead to Europe spreading East? What were the cultural differences that set Eastern expansion against Western defensiveness? 

• These questions militate against pure climatic determinism, thus putting human agency back into the mix. Was one people better organised, or more adaptable, or technologically or culturally better resourced than another, to resist adverse conditions and benefit from favourable ones? Like other forms of fatalism, climatic determinism robs us of decision. As it defines human strategies and policies for making the most of the conditions we inhabit, this enquiry – how we deal with the conditions that confront us - is of first importance. 

• Volcanic eruptions are a constant bass underpinning this vast song of the Earth. Huge clouds of particles block out the Sun, suspend photosynthesis, reduce plant growth and plunge the world into famine, often for years at a time. Some concentrated bouts of eruptions seem to have permanently altered the entire biosphere: but even the lesser eruptions of historical times have brought massive effects. My take on this is that recurrent proposals to artificially introduce reflective particles into Earth’s atmosphere in order to combat global warming by shielding us from solar radiation is absolute lunacy. We will duplicate the effects of all those eruptions: less photosynthesis, reduced crops, smaller harvests, it all adds up to starvation for the world’s burgeoning human population. Worse, it will actually be counterproductive since photosynthesis is the leading means of reducing atmospheric C02. Please, anybody who reads these words, speak out against this dangerous stupidity!

So how to make use of this monumental opus? It is so wide-ranging yet so detailed that any attempt to absorb it in one go is certain to fail: I really tried! Like this book, Frankopan’s earlier and very popular The Silk Roads took a very broad survey of its subject through time and space, but The Earth Transformed feels like it is telling multiple stories rather than just one. This may be why it tends to exhaust rather than inform. Much better to take it as a reference book. Dip into particular epochs or cultures or places in the massive index, read what amounts to an essay on the subject you are exploring, then investigate further using Frankopan’s notes, while checking out names, places, movements, technologies etc on Wikipedia. All the best with that!
