Meteorologist Tom Wysmuller: ‘The Recent Temperature and CO2 Disconnect’ -- Even going back ten centuries, there have been total disconnects between temperature and the CO2 impact, or lack thereof. From 1000AD to 1800, over a period of relatively stable CO2 values that bounced around the 280ppm level, temperatures plummeted in the Little Ice Age (LIA) and then rebounded over a century later. CO2 values neither led nor followed the temperature declines and recoveries…CO2 seems to have had little impact in EITHER direction on the observed temperatures over that 10k year period…If CO2 is to be considered a major driver of temperatures, it is doing a counterintuitive dance around the numbers.’
“In terms of [global warming’s] capacity to cause the human species harm, I don’t think it makes it into the top 10,” Giegengack said in an interview in the May/June 2007 issue of the Pennsylvania Gazette. (LINK) Giegengack also noted “for most of Earth’s history, the globe has been warmer than it has been for the last 200 years. It has rarely been cooler.” (LINK) “[Gore] claims that temperature increases solely because more CO2 in the atmosphere traps the sun’s heat. That’s just wrong … It’s a natural interplay. As temperature rises, CO2 rises, and vice versa,” Giegengack explained. “It’s hard for us to say that CO2 drives temperature. It’s easier to say temperature drives CO2,” he added. (LINK) "The driving mechanism is exactly the opposite of what Al Gore claims, both in his film and in that book. It's the temperature that, through those 650,000 years, controlled the CO2; not the CO2 that controlled the temperature," he added. (LINK)
“Certain ‘feedback loops’ naturally control the levels of greenhouse gases in the atmosphere. A warmer temperature drives gases out of solution in the ocean and releases them,” he continued. “[Today, humans] are putting 6.5 billion tons of fossil-fuel carbon into the atmosphere, and only 3.5 billion is staying there, so 3 billion tons is going somewhere else. In the past, when the Earth’s climate rose, CO2 came out of the ocean, the soils, and the permafrost. Today as temperatures rise, excess CO2 is instead going into those and other reservoirs. This reversed flux is very important. Because of this, if we reduced the rate at which we put carbon into the atmosphere, it won’t reduce the concentration in the atmosphere; CO2 is just going to come back out of these reservoirs ... If we were to stop manufacturing CO2 tomorrow, we wouldn’t see the effects of that for generations,” Giegengack said.
