Science professor skeptical of global warming
Letter From Jon Hartzler
Ph.D. and retired science professor, Hutchinson, Minnesota


30 Jun 08 – “In science, proof of an effect requires a tight experiment, including large numbers of repetitions and rigid controls. Climate has far too many variables to lend itself to this requirement for proof. We are left with what we call correlations, like increasing carbon dioxide and increasing temperature. This is not proof, only suggestive in science.

Indeed the latest scientific report (Intercontinental Report on Global Climate Change 2007) stated we are 90 percent convinced. So even the much-heralded report contains an admitted element of uncertainty on the part of the scientists who wrote it.

… many scientists are skeptical. Some dissenters include world-class names, like Prof. Richard Lintzen, former director of earth and planetary physics at Harvard University and present professor of meteorology at Massachusetts Institute of Technology, arguably the best scientific institution on the planet.

Another Ph.D. dissenter is Prof. Richard Lindgren. … Lindgren wrote in the Wall Street Journal April 2, 2006, how scientists who dissent in the global-warming debate are intimidated and their science is squelched. They lose their jobs in academia, editors won’t publish their research, the media and pro-global warming advocates make fun of them, trying to make them look stupid. Like Lofdahl did in his bashing of the 31,000 scientists signing the anti-global warming document.

No wonder we don’t often hear dissent on the global-warming issue. Did you go see “Expelled?” It pictures an all-too-real academic environment.

Does it make sense for the U.S. to spend billions of dollars to try to fix Mother Nature? We humans are mighty arrogant if we think we can, particularly when you factor in China with its billions of people and uncooperative nature. The Chinese laugh at the Kyoto Protocol and the “civilized” world trying to fix “global warming.” Our puny little effort (but very costly) when China refuses and puts their economy first makes us seem insignificant. Other huge, developing countries like India also complicate the situation.

It seems to me there are lots of reasons for an informed person to be skeptical of global warming and its “solutions.” Also, no one seems to acknowledge the huge benefits to crop production of warmth and carbon dioxide.

Factor in reduced heating costs for us. I say let it warm up, so I don’t need Florida!”
