COAL COMSUMPTION 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 tons of carbon dioxide
to the atmosphere yearly. This tends
to make the air more effective blan-
ket for the earth and to raise its
temperature. The effect may be con-
siderable en a few centuries.
