Dividing line: The past, present and future of the 100th Meridian

In 1878, John Wesley Powell first advanced the idea that the climatic boundary between the United States’ humid East and arid West lay along the 100th meridian, which
runs from pole to pole and, today, cuts through six U.S. states. But what does it really mean, and what is its future?

Nautical charts reveal coral decline around Florida Keys

Coral reef cover is known to have decreased over the past few decades, but longer term estimates of coral cover have been difficult to reconstruct. In a new study, researchers used high-resolution historical nautical maps from the 18th century to determine changes to reefs in the Florida Keys.

Benchmarks: September 23, 1806: Lewis and Clark's Corps of Discovery returns from the West

It’s been called the greatest camping trip of all time. Statues, counties, waterways, mountains, military vessels, and even two colleges bear the names of the journey’s leaders. Their journals are among our greatest national treasures, and their adventures have inspired generations of explorers. Two hundred and eleven years ago this month, Captains Meriwether Lewis and William Clark and their 31-man Corps of Discovery returned to St. Louis, the frontier town where they had started their journey 28 months and nearly 13,000 kilometers of wilderness earlier on May 14, 1804.

Benchmarks: October 2, 1574: Dutch unleash the ocean as a weapon of war

In 1574, the city of Leiden in the Netherlands was brought to its knees: By August of that year, about 6,000 of the city’s roughly 15,000 inhabitants had either starved to death, been killed by the Black Plague or had succumbed to dysentery. Plague doctors in their crow-beaked masks roamed the streets amid famished and diseased citizens drinking foul water from canals. No one knew when, if ever, help would come, for beyond Leiden’s walls the Spanish army was laying siege and cutting off all supply routes into the city.

Bad weather hampered Mongol invasion of Europe

In 1241, the armies of the Mongol Empire, continuing their campaign through Asia and Europe, invaded western Hungary. Before long, however, the Mongols withdrew their forces, beating a sudden retreat that has long baffled historians. Now, drawing on high-resolution climate data from tree rings, researchers may have found a clue as to why: It seems wet weather created adverse conditions for the Mongol army, eventually forcing it to retreat from what was to become historically its westernmost advance.

Volcanoes and historical politics

As well as influencing art and faith, volcanoes are often portrayed as the very manifestation of the human condition. Expressions of anger are readily described as “volcanic.” They have become a metaphor for anything of suitable magnitude or wrath. One such painting sees a volcano become the embodiment of the French Revolution.
