Obama and the Crash of 2013. Peter Ferrara

global warming is false. Published peer-reviewed papers by Richard Lindzen, Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology, find that a doubling of carbon dioxide (CO₂) in the atmosphere (currently up only 44 percent from preindustrial levels) would increase temperatures by 0.7 degrees Kelvin, less than half the estimate of the theoretical climate models used by the U.N.’s Intergovernmental Panel on Climate Change (IPCC), on which the EPA exclusively relies.

      Another published paper by Roy Spencer, U.S. science team leader for the AMSR-E instrument flying on NASA’s Aqua satellite and the principal research scientist for the Earth System Science Center at the University of Alabama at Huntsville, uses atmospheric temperature data from NASA’s Terra satellite to show that much more heat escapes back out to space than is assumed to be captured in the atmosphere by greenhouse effects under the U.N.’s theoretical climate models. This explains why the warming temperature changes predicted by the U.N.’s global-warming models over the past 20 years have been so much greater than the actual measured temperature changes.

      In August 2011 came the results of a major experiment by the European Organization for Nuclear Research (CERN) involving 63 scientists from 17 European and U.S. institutes. The results show that the sun’s cosmic rays resulting from sunspots have a much greater effect on Earth’s temperatures through their effect on cloud cover than the U.N.’s global warming models have been assuming. This helps to explain why the historical pattern of temperature changes seems to follow the rise and fall of sunspots rather than the concentration of CO₂ in the atmosphere. This further confirms what Heartland’s Climate Change Reconsidered argues – that natural causes, not greenhouse gases, have the dominant effect on Earth’s temperatures.

      Finally, the U.N.’s own climate models project that if man’s greenhouse-gas emissions were causing global warming, there would be a particular pattern of temperature distribution in the atmosphere, which scientists call the fingerprint. Temperatures in the troposphere portion of the atmosphere above the tropics would increase with altitude, producing a “hotspot” near the top of the troposphere, about 6 miles above the earth’s surface. Above that, in the stratosphere, there would be cooling. But higher-quality temperature data from weather balloons and satellites now show just the opposite: no increasing warming with altitude in the troposphere above the tropics but rather a slight cooling, with no hotspot, no fingerprint.
