"What Causes Climate Change" Part-I, The trivialities of the human-caused greenhouse effect. By Terigi Ciccone, Dr. John Doner | November 12th, 2020 | Reads the NASA headline,i followed by this lead paragraph: "Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"— warming that results when the atmosphere traps heat radiating from Earth toward space. The authors addressed this question in many articles, posts, and discussions concerning the many Natural Cycles as the dominant force for climate change. But NASA wants to make us think that CO2, and more specifically Human-made CO2, is the dominant force that we need to focus on and control if we are to save the planet. In this segment, we get some help from famed atmospheric physicist Fred Singer and see what he has to say. According to Dr. Singer, CO2 does not dominate the radiative forcing of climate change. It is Water Vapor that rules the Greenhouse Effect. For this exploratory journey, we will use an article by Fred Singer, which was initially published as a Letter to the Editors of the Wall Street Journal, ii titled "Water Vapor Rules the Greenhouse System." We will focus on answering the following critical questions: • • •

What are the greenhouses gases? How much does each greenhouse gas contributes to the overall greenhouse effect? Lastly, determine what the human contribution to the greenhouse effect is?

We will use this article to quantify, compare, and contextualize the exact role CO2 and methane plays in the greenhouse effect and compare it to all greenhouse gases and water vapor. We will determine how much of these greenhouse gases are human-made and compare that with nature made portion. In a subsequent Part -II, we will see if or how this human-caused greenhouse effect may or may not correspond to a change in radiative forcing. Table 1 uses values from October 2000, when the CO2 atmospheric concentration was about 368 PPM. The latest measurements indicate that CO2 has reached nearly 420 PPM, but the comparative base remains equally valid today. It's hard for the average person to reconcile these PPM values. So, let's use a slightly different scale that more familiar in our daily lives. Let us put 1,000 dots on a piece of paper to represent the major gases in the atmosphere. 780 of those dots are for nitrogen, 210 for oxygen, 9.3 dots for argon; we already have used up 999.3. That leaves only a trivial 0.04 of a dot for CO2 and 0.03 for all the remaining gasses. 1
