Several aspects of the Global Warming debate fascinate me. One is argument that there is no debate. I consistently read that 97 percent of scientists believe it is real and is caused by man. There was a petition by Dr. Art Robinson that disputed that assertion, and over 33,000 people with at least Bachelor of Science degrees signed it. It was attacked because there were a few “fake names” used in the signatures. Let’s pretend some portion of the signatures were valid. I’ll pick that there were 30,000 legitimate scientists who signed the petition. There would have to have been 1,000,000 scientists who disagreed with the petition for the 97 percent assertion to be valid. Another attack against the petition is that the scientists who signed it weren’t experts in climate science. I signed it, and am guilty as charged. I am not an expert in climate science, but consider that I have a rudimentary understanding of scientific methods.
One of my work assignments was pretending to be the manager for several scientists with advanced degrees. They often enjoyed arguing with each other about scientific interpretation. I’m trying to imagine how disgusted they would have been if I had stepped into the middle of a discussion and declared “The science is settled.” (I think that statement, which I consider to be absurd, explains why I persist in questioning/denying.)
Another aspect of the discussion or debate is that the lower temperature last year was optimal. It seems that only negative effects can result from the temperature increasing. Of course there are several positive effects of warmer temperatures, such as increased yields for some crops. But, according to NPR, even that isn’t a positive. Global warming, according to the reports, could cause a shortage of salad. Warmer temperatures caused the Arizona lettuce harvest to wrap up early and central California, which fills the salad needs after Arizona drops off, had heavy precipitation that delayed some plantings. I agree this is terrible, because I really like salads. And apparently there will be a shortage unless we stop the many human activities resulting in carbon dioxide emissions that cause higher temperatures and increased localized precipitation? Or maybe it’s too late! So far I’ve been able to buy all the salad-making materials I want, but I guess I should live in fear that is about to end because of global warming?
