Letter to the Editor Regarding Global Cooling

This morning has a brief letter from a Bill Downall responding to another letter written by John L. Sorg. I don't recall Sorg's letter but apparently he had pointed out that global temperatures have actually fallen since 1998. Downall claims the weather was an anomaly that year due to an El Nino. He then criticizes Sorg's approach at looking at only a ten year snapshot of the weather arguing that it is like saying the Colts are a terrible team if they haven't scored in the past five minutes.

Of course Downall is correct, although his math is off. (Ten years in the 4.5 billion year history of a our planet is much less than five minutes of a sixty minute football game.) What Downall apparently doesn't realize though is that he is pointing out the very flaw in the science used by global warming alarmists.

Whether it is ten years used by Sorg or the 114 years of recorded weather data used by those sounding the global warming alarm, both are tiny snapshots of our climate. The 4.5 billion year history of the planet has been dotted by ice ages and warming periods. In between those climate shifts are shorter-term zigs and zags in temperatures that last hundreds if not thousands of years. You can't just simply take a 10 year or a 114 year period of weather data, feed it into a computer, and extrapolate the data to reach conclusions about long-term weather patterns.

The science of climatology has evolved to the the point where they can fairly accurately analyze weather pattern from millions if not billions of years ago. There is no reason to focus on just the recorded weather data which started being kept in the late 1800s, except that being selective about the data supports a political agenda. Let's have an open and honest debate about global warming, using all the climate data. Of course that may well disprove the global warming alarmists like former Vice-President Al Gore.
