A picture of a newspaper reading: THE RODNEY AND OTAMATEA TiMES, WEDNESDAY. AUGUST 14 1912 Science Notes and News. COAL CONSUMPTION AFFECT- ING 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.
