In the future science will probably realize that global warming is just the "effect" from the conjunction of these various cycles.An effect that repeats itself in a planetary supercycle every billions of years or so.

I've thought for some years that what is being cried up as "global warming!!!-quick,we have to turn off the peasants' air conditioners!!!!"is,if it exists at all,simply part of a cyclical weather pattern that happens on a timescale that is long enough for us puny humans not to recognize.

An example of this could be Atlantic Coast hurricanes:according to a WSJ article that I read some years back,the hurricanes that hit the Atlantic shores run on a fairly predictable 20 year cycle. The things occur periodically,but you have to have good records for several hundred years to be able to see the pattern. Since most of the people who write articles on science for a popular audience have an attention span that is measurable in hours,at the most,this sort of observation seldom makes it into print,IMO. Let's don't even talk about the attention span of television reporters...
