...release of carbon dioxide from the burning of coal would probably cause the temperature of the atmosphere to rise, he said. However, he added that, "There are so many factors involved and no one knows how the long range cycle of warming and cooling will work...
...effects of a higher carbon dioxide level will not be known for ten to 20 years, Heinrich Holland, professor of Geology, said yesterday...
...Holland added that he does not foresee any serious effects in the future. "We've already probably increased the carbon dioxide level in the atmosphere by 15 to 20 per cent since 1850 and there's been no immediate effect on the earth's climate," he said...
Michael B. McElroy, Rotch Professor of Atmospheric Sciences, said yesterday, "Climates can change considerably so adding carbon dioxide to the atmosphere...
