I wonder if climate change was going on in 1976? That's 226 years after the Industrial Revolution began.<quoted text>
"1976 - The Big Thompson Canyon Flood happened in late July after a thunderstorm refused to move from the area - dumping more than a foot of rain in less than five hours. Recordkeepers say it is one of the deadliest freshwater floods in US history. In less than two hours, 570 structures were destroyed and 145 people lost their lives. The flood cost around $40 million."
