One of the very first climate change models was actually constructed by an amateur scientist named Guy Callendar in the early 1930s, according to WIRED. He started collecting measurements of atmospheric gases, looking at the affects of fossil fuels, and making notes about the ocean’s currents, temperature, and rainfall worldwide. He ultimately created the first rough draft of a modern-day climate model, and in 1938, he discovered that humankind’s carbon emissions were raising the earth’s temperatures.
Callendar presented his findings to a panel of climate scientists at the Royal Meteorological Society, and was promptly shut down, because at the time, carbon dioxide levels in the air were low, and the idea seemed outlandish. However, Callendar kept researching what he called the “Callendar effect,” looking at small increases in temperature, which he thought would postpone the return of the ice age. Sadly, he died in 1964, with not much progress under his belt.
In the early 1970s, rumors sparked regarding humankind’s negative effect on the environment, according to Scientific American. Climate curiosity started morphing into anxiety and concern, and the greenhouse effect was eventually established and defined by a handful of scientists. They noted the industrial age had “put dust and smog into the atmosphere,” which could block the Earth’s sunlight, thus inching closer to what climate change really is.
