I found this image on reddit, and I'm wondering if this is real? Was this actually published over 100 years ago?

COAL CONSUMPTION AFFECTING CLIMATE
The furnaces of the world are now burning about 2,000,000,000 tons of coal a year. When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the Earth and to raise its temperature. The effect may be considerable in a few centuries.
