It gives one pause to think back to the origins of “climate science” in the 18th and 19th centuries, and to know that sunshine was being electrically recorded back then. I wonder where the data from these readouts is now, and if it’s available online for data mining… Anyway, climate science is not new. An article on the greenhouse effect was published around time of the first Friez catalog:
On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground
