What's happened
Recent research links the 1345 volcanic eruptions to the Black Death's outbreak in Europe. Tree rings, ice core data, and historical records suggest climate change caused crop failures, prompting trade routes that inadvertently spread Yersinia pestis, leading to the pandemic. The study highlights climate's role in historical pandemics.
What's behind the headline?
Climate as the Catalyst
The new research underscores the critical role of climate in shaping historical pandemics. The volcanic eruptions around 1345 caused a 'perfect storm' of environmental stress, including crop failures and famine, which heightened vulnerability to disease.
Trade and Disease Spread
The study highlights how medieval trade routes, especially those connecting Italy to the Black Sea, inadvertently facilitated the transmission of Yersinia pestis. The economic necessity to import grain from plague-affected regions increased contact with infected rodents and fleas.
Broader Implications
This research exemplifies how climate events can trigger societal vulnerabilities, leading to pandemics. It also offers a cautionary tale for modern globalisation, where climate change and interconnected trade could similarly amplify disease outbreaks.
Future Outlook
Understanding these historical links emphasizes the importance of monitoring climate and ecological changes today. As global warming continues, the risk of zoonotic diseases emerging and spreading may increase, making climate resilience a key component of pandemic prevention.
What the papers say
The articles from Ars Technica, Sky News, and The Independent all converge on the idea that climate change, driven by volcanic eruptions, was a key factor in the Black Death's emergence. Ars Technica emphasizes the scientific methods used, such as ice core and tree ring analysis, to establish the eruption's timing. Sky News highlights the sequence of environmental and societal factors, including famine and trade routes, that led to the pandemic. The Independent focuses on the historical context, noting the role of trade and the spread of Yersinia pestis. While all agree on the climate connection, Ars Technica provides detailed scientific evidence, whereas Sky News and The Independent contextualize the societal impacts, illustrating a comprehensive picture of how environmental factors catalyzed one of history's deadliest pandemics.
How we got here
The Black Death, which killed up to 50 million people in the 14th century, has long been linked to the bacterium Yersinia pestis. Recent studies combine climate data, tree rings, and historical records to suggest that a volcanic eruption around 1345 caused prolonged cooling and crop failures across Europe. These conditions led to famine, economic strain, and increased trade activity, which facilitated the spread of infected fleas via ships from Central Asia to Europe. This chain of environmental and societal factors created the perfect storm for the pandemic's rapid spread.

How Did Climate Change Contribute to the Black Death?
Recent research reveals a fascinating link between climate events and one of history's deadliest pandemics, the Black Death. By examining volcanic eruptions, tree rings, and ice core data, scientists are uncovering how environmental factors may have set the stage for the spread of Yersinia pestis across Europe. This raises important questions about the role of climate in shaping historical and modern pandemics. Below, we explore how climate change influenced the Black Death and what lessons it offers today.

The Black Death was the deadliest pandemic recorded in human history. The Black Death resulted in the deaths of up to 75–200 million people in Eurasia and North Africa, peaking in Europe from 1347 to 1351.

Yersinia pestis is a gram-negative, non-motile,
rod-shaped, coccobacillus bacterium, without spores that is related to both Yersinia pseudotuberculosis and Yersinia enterocolitica.
