Riding the waves of mutability has always been possible if the frame of mind in government and society is adequately supple and responsive. Reliance on ancient nostrums, and expectations that old solutions will remain good enough, are almost inevitably fatal.

Civilisations that become dependent on large, widespread and complex supply networks and reciprocal markets usually generate their own fragilities. If one part of such a network fails, the effects cascade in a series of chain reactions through all apparently powerful participants in the system

The end of the Bronze Age c.1200 BC, perhaps triggered by drought in Anatolia, may have precipitated one such domino collapse, as the Hittite empire, the Mycenaeans, the Mesopotamian states and Pharaonic Egypt all either fell apart or shrank to an unrecognisable impotence.

Volcanoes are the unexpected killers. Their spewing of ash into an atmosphere whose winds distribute it around the globe has repeatedly destroyed summers, devastated crops, induced famines and collapsed societies

In his hands, the triumph of the West, with the unconscionable horrors of the Atlantic slave trade at its heart, takes on the appearance of an alarming fusion of Faust and Midas. For centuries, Europeans felt they could do no wrong. They could use the world, its people and beauties. They could transform it as they wished, shifting its plants, animals and populations where they wanted, and there would be no consequences. Or at least, as in those two myths of the cult of ‘entitlement’ – a word Frankopan repeatedly uses of the transforming empires – the consequences were hidden from the perpetrators.

His story of destruction over the past two centuries is one of arrogant myopia which led in the 20th century to ‘a sequence of catastrophes unparalleled both in human history and in that of the natural world. The suffering of the past 100 years has been by far the greatest in recorded history in terms of its scale and its horror’.

The assumption that man must conquer nature was allied to the capital and industrialised capacity to bring it about. Humanity became its own climate. Its own actions created the world in which it lived

The value of this book is as an act of deep understanding, recognising not only scientifically but culturally and philosophically that we are epiphenomena – not dominators of the Earth but products of it

Bleakly and soberingly, Frankopan recognises from the long line of precedents that the prospects are for a world of war and suffering. The destructive changes are already ‘baked in’. Success does not breed success, he says, but more often than not ‘sows the seeds of ruin’.

A handful of financial institutions produced them when Rio de Janeiro hosted in 2016, using a mixture of macroeconomic indicators and performances at previous Olympics to forecast total medal hauls for each country.

Gracenote’s distinguishing feature is the ability to produce quantitative analysis for each event.

Gracenote still uses the old system to produce its public medal table, which also deals in absolute forecasts, rather than fractional ones. If a French athlete, say, is the most likely to win an event, France gets awarded one gold medal in the table, even though the true probability of the athlete winning gold is less than 100% and his chances of claiming silver and bronze are greater than 0%.

the Elo rating system, which was developed for chess by Arpad Elo, a Hungarian physicist. The formula exchanges ranking points from the loser to the winner, with greater rewards for beating stronger opponents. The difference in ratings points between two rivals can be easily used to calculate the probability that one will beat the other.

Yet only two events on the winter Olympics programme, curling and ice hockey, involve head-to-head contests.

Those that compete in teams have their scores blended with their compatriots. And for those that participate in a number of events, such as Ms Dahlmeier, results in related disciplines affect multiple ratings. A strong performance in the biathlon sprint, a group race, would boost her ranking in the pursuit, a staggered race, for example.

The best way to answer that question is to take every previous contest in the sport and analyse how past results correlate with future success.

The bans have benefited Norway most, as the country will likely gain of the five of the 12 foregone medals—enough to nudge it ahead of Germany into first place in terms of total medals won.

Mr Gleave notes that the favourite only wins about 30% of the time, a lower share than in any other winter sport. Ms Dahlmeier’s rating has dwindled a little, but not by enough to suggest that last year’s record breaker has become this year’s flop.

Gracenote’s research into age curves for each sport shows that the best biathletes can maintain their peak performance into their early 30s (see chart). Expect to see more event-by-event forecasting at future Olympics, too.
