Climate Change and the Bubonic Plague in the 14th Century

~3 min read

Abstract

This paper examines the relationship between climate change and the Bubonic Plague during the 14th century. It describes how the Medieval Climate Optimum — a prolonged warming period lasting from roughly the 10th through the 14th century — created environmental conditions that facilitated the spread of disease, particularly the Bubonic Plague, which killed approximately 34 million people across Europe and Russia. The paper draws on scientific commentary linking warm, wet weather to disease transmission and explores the far-reaching consequences of mass mortality on labor markets, political structures, religious institutions, and financial systems. It also briefly connects these historical patterns to contemporary concerns about climate change and emerging infectious diseases.

What makes this paper effective

It grounds a broad historical topic — the Black Death — in a specific environmental cause, giving the analysis a clear and focused argument.
It draws on a contemporary scientific source (Stenseth's 2005 conference remarks) to bridge medieval history and modern climate concerns, adding relevance and credibility.
The paper efficiently traces consequences across multiple domains — labor, religion, politics, and finance — without losing its central thread.

Key academic technique demonstrated

The paper uses a direct quotation from a named scientific authority to support its central claim, then situates that claim within a longer historical pattern. This technique — anchoring an argument in expert testimony before broadening to systemic consequences — is an effective way to establish credibility early and sustain it through the rest of the analysis.

Structure breakdown

The paper opens by defining the Medieval Climate Optimum and establishing the historical context. It then introduces the Bubonic Plague as a climate-linked disease event, supported by a sourced expert quotation. The third movement addresses the social fallout of mass death, covering labor, religion, and politics. The paper closes by connecting these historical patterns to present-day climate trends, giving the essay a forward-looking conclusion. References are listed in a Works Cited section consistent with MLA style.

Introduction: The Medieval Climate Optimum

During the 10th through the 14th century, a warm climate predominated in Earth's weather. Called the Medieval Climate Optimum, it affected politics, religion, labor, finances, science, and population changes among humans on Earth by creating conditions ripe for the spread of disease, which in turn generated profound human problems. This warming period was followed between 1425 and 1850 by what is known as the Little Ice Age.

Climate, Disease, and the Bubonic Plague

Nils Stenseth, who headed a three-day conference on avian influenza in 2005, noted that in the past, similar diseases have appeared during periods of warm weather. During the 14th century, comparable weather conditions appear to have aided the spread of the Bubonic Plague, which killed around 34 million people in Europe and Russia. The disease spread through birds, fleas, and rats that carried those fleas. It did not disappear completely, and some academics believe it reappeared as the Great Plague of London in 1665–66.

"The link is very important and it is also important to link it back to the Black Death in the 1300s because there were the kind of weather conditions then — warmer and wetter — that we predict for the future," Stenseth said. "After 1855, when it [plague] reappeared again, there were once again similar weather conditions" (Kilner, 2005).
