Full Eclipse Coming, and The Lunar Cycle (2nd in a Series)

Posted by The Diatribe Guy on February 17, 2008

As I was taking a look at the weather site this evening with my 6-year old (trying to find out whether the 8 inches of snow we’d already received today was going to stop sometime before our house was buried) he saw a little video box that he asked me to play. Of course, as soon as I did, he lost interest and fled away to his next pursuit, but I was glad he had drawn my attention to it. Little did I know that this coming Wednesday, February 20, there will be a full lunar eclipse! This doesn’t come around all that often, and as luck would have it it’s supposed to be below zero degrees Fahrenheit when it happens, but you can bet I’m going to be checking that out.

Well, this got me thinking about something I had put together some time ago. Almost a year ago, when I was on one of my Global Warming/Climate Change kicks, I started doing research into the concept of cycles. I had intended to post a series about my research, but soon life took me in another direction and I failed to follow through. As a concept, it is my contention that Climate Change is effectively driven by a complex array of cycles. These cycles range from the daily cycle of a rotation of the earth, to monthly cycles relating to the moon, to the annual revolution of the earth, and so on and so forth. There are earthly cycles, solar cycles, axis oscillation cycles, and even cycles in our solar system and galaxy that can impact our planet. The contention I had was that everyone understands and expects the short cycles. By simple experience, we observe them, and while there are scientific explanations to everything, we don’t need a climatologist to explain to us that earth is warmer during the day and cooler at night, or that summer is hotter than winter. But I think we too easily dismiss other cycles that we do not understand as well, or those that go on for centuries or millennia, since we do not ever observe a full cycle. Instead, we convince ourselves that there is something unusual about changes we see going on today because it is different from a few decades ago, and the conclusion is that we are somehow causing it. I think we give ourselves too much credit.

Well, anyway, My “first in a series” post (almost a year ago) is here. It deals with the “one day cycle.” Read the rest of this entry »
