The world always seems to be ending. This past summer, as wildfire smoke hung over much of Ontario, I tried my best to shelve my climate anxiety only to end up reading four-hundred-year-old sources describing similar experiences. No matter where I looked, the world seemed on the brink of disaster.
My dissertation explores environmental crisis and apocalyptic thought in late-Tudor England. I read cheap print—sermons, pamphlets, and almanacs—to understand how strange weather was experienced as an apocalyptic phenomenon. In the last decades of the 1500s, we read of ‘signs and tokens’ — comets, eclipses, severe thunderstorms, double rainbows, freakish snowstorms, and floods. In 2026, we saw one of Canada’s worst wildfire seasons ever. On top of this, extreme heat, flooding, and drought persisted across the country. Readers will be interested in Elbows Up for Climate, an interactive site that maps Canada’s many environmental disasters this year. It is hard not to feel fear and anxiety looking at this map. These reactions, however, are useful to make dynamic what is often presented as static. Because of the catharsis, fear, and wonder that sprang from observing signs in nature, sixteenth-century people read moral warnings and affirmations into them. Understanding their reality helps make sense of ours.
As a historian of the sixteenth century living through ‘unprecedented times,’ complete with climate disasters and large segments of the population living in apocalyptic expectation, I am uniquely positioned to show how precedented our experiences are. In this short essay, I spotlight an earthquake that shook London in 1580, one example from a generation that witnessed environmental disasters alongside political crises, religious reform, and technological advances. Using this case study, I bring the apocalyptic rhetoric I study into conversation with our own contemporary language. This exchange encourages empathy for historical actors we might otherwise view as superstitious or simple. Empathy for the past means recognizing where we can see ourselves by working to understand what is unfamiliar.
