10/10/17 – Let Sleeping Volcanoes Lie
October 10, 2017Iceland has always loomed large in my mind, its geographic extremes and stark beauty placing it high on the list of places I want to explore during my lifetime. The volcanic island’s larger-than-life reputation in my head belies its true size, which is about that of the state of Oregon. Iceland has, however, had a giant impact on the rest of the world at several different points in history when its volcanoes cast poisonous gases and ash into the atmosphere. While physically isolated from the rest of the globe by the cold waters of the North Atlantic, scholars are increasingly recognizing how connected the island’s environmental history is with world history.

The effects of the massive eruption outside of Iceland began with a “dry fog” that reached Norway and northern Scotland two days after the eruption, France ten days after, and England by June 23. According to historical sources, during the summer of 1783 a haze hung thick over Europe, trapping heat and causing all manner of respiratory and heat related distress in humans (in many cases leading to death) as well as crop disease and failures. The heat and haze spawned violent electrical and hail storms that caused their own forms of damage. As the haze dissipated in the fall, frosts came early and the winter of 1783-1874 was bitter on the European continent. Witze and Kanipe narrate the links researchers have found between the bitter cold and the sulfur Laki spewed high into the atmosphere that winter, increasing global albedo (reflection of sunlight) and redirecting warm jet streams. Though the Laki eruption ceased in February 1784, the summer of 1784 was cool and winter again came early. Two years of unpredictable weather and bad harvests led to widespread famine, disease, and social unrest around Europe – including in France. Witze and Kanipe describe how some researchers postulate that Laki may have even been a significant factor in the French Revolution that happened a few years later, in 1789.[v]

Eugene Delacroix’s 1830 painting of the French Revolution, “Liberty Leading the People.” Some scholars have linked the French Revolution, at least in part, to Laki’s disruption of crop cycles.[vi]

[1] To have a global effect, volcanic eruptions need to send gas and dust high enough into the atmosphere to reach jet streams. Many famous eruptions, such as that of Mt. Vesuvius near Pompeii in AD 79, were smaller and more localized in their (still catastrophic) effects. The global effects of massive eruptions were less well-known before modern climate science emerged, though in the case of Laki several scholars did postulate that the haze they were seeing could be connected to Iceland.
