Often when seeing anti-environmental commentary about global warming in the media, I feel like the first question I would like to ask these commentators is: “Why do you deny that carbon dioxide (CO2), which is increasing in an unprecedented way in the atmosphere, is a greenhouse gas?”
If they were to start their answer: “I don’t deny it …” I would think “Good, we’ve made some progress.” However, as I think would often be the case, if they start their answer: “Because …” we should be ready to pounce on the ensuing nonsense.
Here’s a key example of such nonsense from a former weatherman:
“Now allow me to talk a little about the science behind the global warming frenzy. I have dug through thousands of pages of research papers, including the voluminous documents published by the United Nations Intergovernmental Panel on Climate Change. I have worked my way through complicated math and complex theories. Here’s the bottom line: the entire global warming scientific case is based on the increase in carbon dioxide in the atmosphere from the use of fossil fuels. They don’t have any other issue. Carbon Dioxide, that’s it.
Here is the deal about CO2, carbon dioxide. I estimate that this square in front of my face contains 100,000 molecules of atmosphere. Of those 100,000, only 38 are CO2; 38 out of a hundred thousand. That makes it a trace component. Let me ask a key question: how can this tiny trace upset the entire balance of the climate of Earth? It can’t. That’s all there is to it; it can’t”.
