" this is NOT the only problem with the adjustment process. It has nothing to do with the problems identified in Iceland, Paraguay, and other places." It has everything to do with the fact that the planet is warming because of our actions, and acknowledging that means the deniers would have to begin discussing what to do about it. A 50th anniversary few remember: LBJ’s warning on carbon dioxide Fifty years ago this month (today, actually), President Johnson voiced concern over invisible fossil fuel emissions in a special message to Congress. It was the first time a U.S. president warned the nation about our carbon habit.... “Air pollution is no longer confined to isolated places,” said Johnson less than three weeks after his 1965 inauguration. “This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels.” On-target estimate The science on carbon dioxide as known at the time, including forecasts of warming and sea level rise, was detailed in a chapter of a report on environmental pollution issued later that year by the president’s Science Advisory Committee. Pioneering climate scientist Roger Revelle chaired the sub-committee that wrote the chapter in the November 1965 report. While citing a need for better calculations with “large computers,” Revelle’s panel delivered a forecast on growing atmospheric carbon that proved on-target. Coal, oil, and natural gas burning would lift atmospheric carbon dioxide between 14 percent and 30 percent by the year 2000, the panel estimated. In fact, CO2 increased 15.5 percent by 2000, and is 25 percent higher today than in 1965. “Man is unwittingly conducting a vast geophysical experiment,” the report said, echoing language Revelle first had used in a 1957 scientific paper when he was at the University of California, San Diego, Scripps Institution of Oceanography. “Within a few generations, he is burning the fossil fuels that accumulated in the earth over the past 500 million years.”
