Hot off the Griddle: November 21
NOAA's Mauna Loa Observatory maintains the longest-running atmospheric carbon dioxide data set. C. David Keeling of the Scripps Institution of Oceanography began monitoring CO2 there in 1958.

Good morning, and welcome back to The Griddle, a morning menu of fortified items for the busy person's media diet. In 1958, a scientist named C. David Keeling started monitoring the carbon dioxide content of the atmosphere, which was then about 314 ppm, or parts CO2 per million parts of air. Within two years, Keeling could tell it was trending up. The National Oceanic and Atmospheric Administration maintains this data set, known as the "Keeling Curve," to this day.
This morning, the World Meteorological Organization issued its annual Greenhouse Gas Bulletin, which measures levels of heat-trapping gases driving climate change. The WMO reports that 2010 set a new CO2 record, of 389 ppm, indicating a rebound in the global economy and a harbinger of the challenges ahead. And now, more news:
