Why Didn’t Scientists Recognize Global Warming Sooner?
Some did. In 1958, the National Academy of Sciences published a booklet titled “Planet Earth: The Mystery with 100,000 Clues,” which contained this prescient paragraph:
Our industrial civilization has been pouring carbon dioxide into the atmosphere at a great rate. By the year 2000 we will have added 70 percent more carbon dioxide to the atmosphere. If it remained, it would have a marked warming effect on the earth’s climate, but most of it would probably be absorbed by the oceans. Conceivably, however, it could cause significant melting of the great icecaps and raise sea levels in time.http://www.extremeicesurvey.org/index.php/glaciology/
