Tweeted by HistoryInPix an old newspaper article published in 1932 talked about the impact of carbon dioxide to the earth's temperature. To our generation, global warming isn't a new thing. Everyday we talk about renewable energy, energy efficiency, etc, to curb and slow down global warming. But back in 1932, global warming wasn't something serious yet but scientist Dr. Hulburt from Naval Research Lab, U.S.A, had warned about it.
