Hey, It Could Be Worse: "Europe’s Deep Freeze of 1709"

 From National Geographic:

In the first months of 1709, Europe froze and stayed that way for months. People ice-skated on the canals of Venice, church bells broke when rung, and travelers could cross the Baltic Sea on horseback. This freakish winter ultimately claimed the lives of a vast number of Europeans and disrupted two major wars—but to this day, there is no conclusive theory for its cause.

It happened literally overnight in the first few days of 1709. On January 5, temperatures plummeted—not, perhaps, a surprise in European winter. But 1709 was no ordinary cold snap. Dawn broke the next morning on a continent that had frozen over from Italy to Scandinavia and from England to Russia, and would not warm up again for the next three months. During the worst winter in 500 years, extreme cold followed by food shortages caused hundreds of thousands of deaths in France alone, froze lagoons in the Mediterranean, and changed the course of a war. Shivering in England, the scholar William Derham wrote: “I believe the Frost was greater ... than any other within the Memory of Man.”
 
French Freeze
The country most affected by the terrible cold was undoubtedly France. The year 1709 had already started badly. French peasants had been hit by poor harvests, taxes, and conscription for the War of the Spanish Succession. The cold snaps of late 1708 were as nothing to the crash in temperatures that took place over the night of January 5 to 6. In the following two weeks, snow would fall and thermometers in France would drop to a low of -5°F.
In the absence of weather forecasting, the authorities had no time to prepare for what became known as “Le Grand Hiver,” and thousands succumbed to hypothermia before measures could be taken to help them. Animals were not spared either: Numerous livestock froze in their pens, barns, and coops. 
The rivers, canal network, and ports froze, and snow reportedly blocked roads across France. In the port of Marseille on the Mediterranean coast, and at various points along the Rhone and Garonne Rivers, the ice was able to support the weight of laden carts, which places it around 11 inches thick. In cities that stopped receiving provisions, accounts circulated of desperate inhabitants forced to burn whatever furniture they had to keep themselves warm. Paris remained cut off from supplies for three months.

Even the well-off, who could fall back on stocks of food and drink, found that the intense cold rendered them unusable. Bread, meat, and even some alcoholic drinks froze solid. Only hard liquors such as vodka, whiskey, and rum remained liquid. The climatic crisis held both rich and poor in its icy grip. The elite’s sprawling mansions with large windows had been constructed for show, not practicality. In Versailles, the Duchess of Orleans, sister-in-law of King Louis XIV, wrote to a relative in Hanover: “The cold here is so fierce that it fairly defies description. I am sitting by a roaring fire, have a screen before the door, which is closed, so that I can sit here with a fur around my neck and my feet in a bearskin sack, and I am still shivering and can barely hold the pen. Never in my life have I seen a winter such as this one, which freezes the wine in bottles.”

Baby, It’s Cold Outside
Across the rest of Europe, many strange effects of the cold were observed. Numerous witnesses recorded how the abrupt drop in temperature made seemingly solid items brittle. Tree trunks would shatter with a startling cracking sound, as if an invisible woodcutter were hacking them down. Church bells when rung also fractured due to the extreme cold temperatures.
 
In London, “The Great Frost,” as it came to be known, iced over the Thames River. The canals and port of Amsterdam suffered a similar fate. The Baltic Sea was solid for four whole months, and travelers were reported crossing on foot or by horse from Denmark to Sweden or Norway. Almost all the rivers in the north and center of Europe froze. Even the hot springs of Aachen in modern-day Germany iced up. Heavily laden wagons trundled across the lakes of Switzerland, and wolves ventured into villages looking for anything left to eat—which sometimes turned out to be villagers who had frozen to death....
