Trend vs Deviations
Tuesday, February 6th, 2007![]()
Since the recent IPCC Report on Climate Change came out, asserting that global warming is caused by humans and will cause harm if unchecked, there have been a torrent of Op-Eds and blog entries criticizing the report and claiming global warming is a hoax. Unlike Frosty Hardison, I believe in the value of free speech, so I took the time to read quite a few of those articles and blog posts yesterday.
One thing that really bothers me about some of these writings, or the comments of individuals who agree with them, is that they don’t seem to understand any of the science behind global warming. The chief complaint I have is that people don’t understand that global warming is a long-term trend. The thing about a trend is that deviations from it are always possible. For instance, let’s think about the stock market. Over the past 100 years, the long term trend has been an upward climb. However, there have been days, weeks, and even years where the stock market has tanked. Yet overall, the country has been growing, and these “down times” were merely deviations from a long term trend.
