Lately, I’ve received a lot of e-mails from readers asking about the environment and the effect of internal combustion engine exhaust on our climate.
One factor is the effect of CO2 on the environment. My understanding is that CO2 is relatively harmless and naturally occurring.
To try to better understand the latest concern about CO2, I contacted a couple of “experts” who work in the environmental area. I found the answers fascinating and wanted to share them, but when I asked permission to quote them, the answer was absolutely NOT. When I asked why, they answered that they are in the research business and do not want to risk losing a grant from either side of the problem.
In other words, “what answer do you want?” has replaced “what is the correct answer?” as the guide for doing research.
