Yet another letter recently (William Sierichs, Jr.) affirming that anthropogenic global warming is “scientific reality.” Consider the following facts ignored by the global warming alarmists.
Plants consume (via photosynthesis) 7 trillion tons/yr of CO2. Humans are responsible for adding 40 billion tons a year of CO2 to the atmosphere. Where do the other 6.96 trillion tons/year come from? Volcanoes, forest fires, rotting plants etc. In other words, humans contribute one half of 1 percent of the total CO2 circulating through our ecosystem. If we cut our production rate in half (economically catastrophic), we would have a negligible impact on total atmospheric CO2.
Data for the last 400,000 years, as reported by Al Gore in 2005 in the documentary, “An Inconvenient Truth,” show that CO2 and temperature cycle together, but CO2 lags temperature by about 800 years. Higher global temperatures raise ocean temperatures. CO2 dissolved in the oceans, being less soluble at higher temperature, is released into the atmosphere as the temperature rises. Increasing atmospheric CO2 does not cause the temperature to rise; it is a result of the temperature rising.
CO2 absorbs solar radiation only at a specific wavelength (14.77 microns). The first 50 ppm of atmospheric CO2 absorb most of the radiation at this frequency. he next 50 ppm absorb half as much, and so on. At 380 ppm (current level), there are no solar photons left to absorb at this frequency. Tripling the level to 1000 ppm would have no measurable impact on absorption of solar radiation (and, hence, on warming).
There are many other “inconvenient truths,” ignored by global warming alarmists, which totally debunk the irrational conclusions of the IPCC with its fundamentally flawed models.
But if these truths were widely known and the resulting conclusions were confirmed by use of the scientific method, then the money would stop flowing and the political forces that want to control our lives by telling us what kind of vehicles we must drive and what kind of light bulbs we must use would lose their clout. And wouldn’t that be refreshing, for a change?
