Age of Exponentials

Forty-eight Ages of a single planetary century. Each curve below is a proxy for one of the societal and biophysical transformations our epoch has set in motion — from warheads and fertiliser to plutonium in lake sediment and bisphenol-A in seawater. Read alone, any one of them is anecdote. Read together, they are a portrait — perhaps the only portrait — of what it means to live inside an exponential.

This is an open dashboard. The data are real, the sources are cited, the panels are wrong in places we have not yet found. If you know a better series, a sharper reference, a missing Age, or a correction to one already here — tell us. We will revise the record as the record itself revises us.
