Growing Blanket of Carbon Dioxide Raises Earth’s Temperature
Earth’s ground temperature is rising 1-1/2 degrees a century as a result of carbon dioxide discharged from the burning of about 2,000,000,000 tons of coal and oil yearly. According to Dr. Gilbert N. Plass of the Johns Hopkins University, this discharge augments a blanket of gas around the world which is raising the temperature in the same manner glass heats a greenhouse. By 2080, he predicts the air’s carbon-dioxide content will double, resulting in an average temperature rise of at least four percent. If most of man’s industrial growth were over a period of several thousand years, instead of being crowded within the last century, oceans would have absorbed most of the excess carbon dioxide. But because of the slow circulation of the seas, they have had little effect in reducing the amount of the gas as man’s smoke-making abilities have multiplied over the past hundred years.
