Using modern-day computer modeling, scientists have discovered that humanity's earliest push out of Africa and into other reaches of the planet was most likely due to changing long-term weather patterns. The first and only example in this gallery of sustained climate change is here: it initiated the dispersal of people from Africa into other parts of the world.

While weather refers to short-term atmospheric conditions (think of a forecast for how sunny and warm it will be next week), climate refers to long-term changes in overall weather trends over time (decades or hundreds of years). to win the war.īut far more often than humanity seeks to control the weather, the weather does the controlling. The air conditioner made its first appearance in 1902 and in 1974 the Senate Committee on Foreign Relations held a classified briefing on the results of Operation Popeye, a five-year cloud-seeding experiment designed to lengthen Vietnam's monsoon season, destabilize enemy forces there, and allow the U.S. Since then, inventions and technological advances have allowed people to track the weather over time and, in some instances, even control it.Īround 1602, Galileo was the first to conceptualize a thermometer that could quantify temperature, allowing people to track changes in heat. In his 1088 “Dream Pool Essays,” he ponders climate change after finding petrified bamboo in a habitat that wouldn't support such growth in his lifetime. In the forthcoming list, Stacker examines dozens of ways weather has shaped human history, drawing on historical documents, newspaper articles, first-person accounts, and documented weather events.Ĭhinese scientist Shen Kuo was the first person to study climate. Sometimes these events are tied to climate change, other times they represent anomalies that affected the future of air travel or launched eras of famine and disease. Weather has influenced significant events thorughout human history, whether forced migration or the course of a war.
