Industry May Be Warming EarthWASHINGTON, Monday (A.A.P.-Reuter). - United States scientists are planning studies on whether man's pollution of the atmosphere is creating a blanket around the world which is making it warmer.
The U.S. Department of Commerce said yesterday that, during the International Geophysical Year beginning next month, weather experts in the Antarctic would take air samples to check a theory that the earth's climate was gradually warming because the amount of carbon dioxide was increasing.
Officials explained, "Man is pouring an awful lot of carbon dioxide into the air by burning fuels. We do not know how much' of it is staying in the atmosphere or how much is going back into plants - or the ocean, if there is a lot staying in the atmosphere then it is possible that the temperature is increasing.
Carbon dioxide would act as an insulating blanket, stopping the earth from radiating as much heat as it otherwise would into outer space.
