A recent letter puts forth the proposition "Warming Real, Documented." The writer states that Earth's temperature is increasing and cites some statistics from NASA Goddard Institute for Space Studies. The writer goes on to cite the United Nations Intergovernmental Panel on Climate Change report about warm recent years. Other parts of the global warming proposition are then stated, including glacier loss, a possible upcoming ice-free Arctic region, damage to coral reefs and extreme weather events. The writer appears to agree with the conclusion of the UN-IPCC that mankind is responsible for all of this.
As a retired scientist with more than 40 years of experience, including 24 years at Oak Ridge National Laboratory, all I can say about all of this is "rubbish."
I have studied the global warming issue and have amassed a huge inventory of peer-reviewed scientific papers showing that, basically, there is not a shred of scientific evidence that mankind is causing Earth's temperature to rise because of carbon dioxide emissions. I can show, through these papers by some of the world's most knowledgeable scientists, major flaws in the global warming alarmism.
First, carbon dioxide by itself has very little effect on Earth's temperature. The major global "greenhouse gas" is water vapor. The only way that the global warming supporters can make carbon dioxide important is by assigning a large, positive "feedback" factor to it, whereby a small increase in CO2 causes an increase in water vapor in the atmosphere.
Second, Earth has a history of heating and cooling itself. Present temperatures are no warmer than they were during the Medieval, Roman or Minoan Warming Periods. The Ice Ages and interglacial periods of the past several hundred thousand years give testimony to great swings in temperature.
Finally, the disasters so loved by the "warmists" can be shown by data to be false. And, no, scientists who dispute the global warming issue are not "looney toons."
