NYT Charts Levels of Carbon Dioxide in the Air – 1960-2010

New York Times Graphics – An Ominous rise in carbon dioxide in the atmosphere since the 1950s. “China recently overtook the United States to become the largest emitter of carbon dioxide from fossil fuels.”

  • A Scientist, His Work and a Climate Reckoning: “When Dr. Keeling, as a young researcher, became the first person in the world to develop an accurate technique for measuring carbon dioxide in the air, the amount he discovered was 310 parts per million. That means every million pints of air, for example, contained 310 pints of carbon dioxide. By 2005, the year he died, the number had risen to 380 parts per million. Sometime in the next few years it is expected to pass 400. Without stronger action to limit emissions, the number could pass 560 before the end of the century, double what it was before the Industrial Revolution.”
