What’s extraordinary about the impact of the Little Ice Age on the early exploration of North America is not simply the cold, but the complexity of weather, geography, landscape, mythology, and the mutual incomprehension between Europeans and Native Americans.
But still, it was often abnormally cold — not simply for the 16th-century explorers of what is now New England and Canada, but for the Spanish in “La Florida,” the American Southwest, and the English in the Jamestown colony in Virginia. The extreme weather patterns often caused immense suffering among Native American populations as well, decades before European-borne diseases such as smallpox became rampant.
Sam White, a professor at Ohio State University, uses historical and archeological records, along with tree-ring analysis and ice core sampling, to document the complicated impact of the Little Ice Age, which also caused major disruptions in Europe itself. White is an academic, and the level of detail and analysis may occasionally overwhelm the general reader, but the story he tells is a compelling one.
For example, European explorers seized, quite reasonably, on the fact that since the latitude of the mid-Atlantic states corresponded with that of Spain, it should possess a climate and topography like Andalusia, where they could easily grow grain, olives, grapes, and other Old World crops. Canada roughly corresponded to France, and it took the bitter experience of many voyages, shipwrecks, and failed settlements for first the English, then the French to accept the reality of Canada’s fearsome winter seasons.
The Little Ice Age not only brought unprecedented cold and snow to the Americas, but often lengthy drought as well, as attested to by contemporary accounts and tree-ring evidence. Often, the local Indians themselves struggled to grow enough corn for themselves, much less trade it to settlers in Florida and Virginia. Cold and hunger inevitably bred conflict.
Ideas were often as potent as realities. Dreams of cities of gold and silver drove Spanish expeditions from Mexico into the Southwest. At the same time, fantasies of a Northwest Passage motivated repeated conveys of ill-equipped English and French ships into the ice-infested waters of the North Atlantic and Arctic Oceans, often with disastrous consequences.
Spain narrowly decided against giving up its unprofitable St. Augustine colony. In the case of Jamestown, the colonists decided to abandon the place after the “starving winter” of 1610 and were only saved by the providential arrival of a large supply fleet.
After detailing the many failed voyages and abandoned early settlements — from New Mexico to Newfoundland — it is remarkable that, by the early 1600s, four permanent settlements actually survived in North America: two Spanish (Santa Fe and St. Augustine), one English (Jamestown), and one French (Quebec).
As White concludes, European explorers “did not fail only because it was the Little Ice Age — although Little Ice Age climates did pose very real challenges. The failed mainly because they did not know what to expect and how to adapt.”
