摘要

For the past 39 years Charles Keeling and his colleagues at the Scripps Institution of Oceanography in La Jolla, California, have been scrupulously keeping track of carbon dioxide in the atmosphere. No one had done that before, so when we want to know CO_2 levels from before 1958, we have to resort to imperfect records such as ice cores from Antarctica. They suggest that in 1750, before the industrial age, CO_2 made up 280 parts per million of the air. When Keeling began his work, fossil fuel emissions and other sources had boosted the level to 315, and today it is 360. Global, temperatures have also been rising, and most climatologists think the culprit is a greenhouse effect created in large part by the carbon dioxide.
