Anyway, that's how I found this week's fact, which isn't so much weird as it is heartwarming. There was a blog post about how Thomas Jefferson and the telegraph helped create a system of weather stations now known as COOP. I already knew about the COOP system, but I hadn't fully appreciated how much of our climate data—dating back all the way to the early- to mid-1800s—gets recorded by volunteers. COOP stations have basic measuring equipment that allows the volunteers to record temperature, precipitation, pressure, and so on, which they do every day. Even back in 1895, there were at least 2,000 people running COOP stations all over the U.S., including in areas that weren't officially states yet.
