The Keeling Curve Turns 50
Background about the "Keeling Curve," a monthly record of atmospheric carbon dioxide levels that began in March 1958 at an observatory in Hawaii. "The Keeling Curve provided the first clear evidence that carbon dioxide was accumulating in the atmosphere as the result of humanity's use of fossil fuels." Features a slideshow about Charles Keeling and the curve, and links to information about climate change. From the Scripps Institution of Oceanography, University of California, San Diego.
