Those who study climate with out looking at anything above 100 Km, are all about temps, pressures, and lately radiative balance. Those with a focus on the solar activity out to the orbit of the earth are into internal dynamo theory. Those with a focus on the interaction of the solar system with an eye to the focus on SSB with the planets driving the solar cycles are getting closer.
The real prospective that will find answers will be called Astrology, or electric sun, not because they are valid but because if one considers the modulation of the galactic magnetic fields by the local effects of the spiral arms and the density/compression waves they are causing the movement of the spiral arm evolution to progress, as a background through which the solar system is traveling, they will be shoved into those categories.
Once a viewpoint is taken in the long term context of the magnetic field interactions of the heliopause as it moves through the changing terrain of the spiral arms it encounters, at the same timing as we experience interglacial periods, then a proper perspective can be taken on what drives both climate and the solar dynamics, as well as the movement of the planets and sun responding to changes in magnetic flux into and through the heliosphere. This can be extrapolated from the effects seen on smaller scales by the magnetospheres of the planets IMHO. (more…)
