An early warning of the effects of burning fossil fuels from 1912

[6Foot2]

A short article in the 14^th August 1912 edition of the Rodney and Otamatea Times, Waitemata and Kaipara Gazette (a New Zealand newspaper) warns of the effects of burning fossil fuels:

 

 

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.
