The sun's own orbit, he found, has eight characteristic patterns, all determined by Jupiter's position relative to Saturn, with the other planets playing much lesser roles. Some of these eight have orderly orbits, smooth and near-circular. During such orbits, solar activity is high and Earth heats up. Some of the eight orbits are chaotic, taking a loop-the-loop path. These orbits correspond to quiet times for the sun, and cool periods on Earth. Every 179 years or so, the sun embarks on a new cycle of orbits. One of the cooler periods in recent centuries was the Little Ice Age of the 17th century, when the Thames River in London froze over each winter. The next cool period, if the pattern holds, began in 1996, with the effects to be felt starting in 2010. Some predict three decades of severe cold.And according Richard Mackey, writing in the Journal of Coastal Research (Special Issue 50, 2007):
In 2007 Ulysses will send information about the solar poles. This could be decisive regarding the predictions about emergent Sunspot Cycle No 24, including the sim hypothesis. According to the sim [Solar Inertial Motion] hypothesis, this cycle should be like Sunspot Cycle No 14, and be followed by two that will create a brief ice age. During the 1920s and '30s Australia's Bureau of Meteorology published research about the sun/climate relationship, especially Sunspot Cycle No 14, showing that it probably caused the worst drought then on record.Not only has Ulysses found that the sun has reduced its output of solar wind to the lowest levels since accurate readings became available, but it's magnetic field has dropped by 20%. At the same time, the solar system appears to be passing through a galactic dust storm.
Rhodes Fairbridge repeatedly emphasised that the entire field of planetary-lunar-solar dynamics, including gravitational dynamics, has to be studied so the dynamics of terrestrial climate can be understood. An improved understanding of the interaction effects of the sunspot cycles and the lunisolar tidal cycles on the earth's climate is necessary, as Rhodes emphasised. When the influence of solar variability is examined in its entirety (as Rhodes insisted it should be), it is clear that the influence of solar variability on the Earth's climate is strongly non-linear, stochastic and significant.
The solar inertial motion hypothesis predicts that the period from about 2010 to 2040 will be one of relatively severe cold throughout the world. The hypothesis predicts that the emergent Sunspot Cycle No 24 will be quieter than Sunspot Cycle No 23 and just like Sunspot Cycle No 14, the weakest cycle in the last 100 years, which began in February, 1902 and ended in August,1913.
One possibility is an increased number of sporadic meteors, those not associated with known showers like the summer Perseids or the November Leonids. Meteors are created when something vaporizes in Earth's atmosphere. Space rocks as big as peas and baseballs crash through now and then, but most shooting stars are made of mere dust.Indeed.
It's also possible, Landgraf said, that the eerie Zodiacal Light -- a "false dawn" caused by sunlight reflecting off space dust -- will be enhanced.
And in general, more material might rain down to Earth from space every year.
You first take the modern sky accessible to science, especially during the Space Age, and you look at its' darker debris with a view to relating its behavior to the more accessible human history which we can, in principle, really understand. And by this approach you discover from the dynamics of the material in space which I'm talking about that a huge comet must have settled in a Taurid orbit some 20,000 years ago, whose dense meteor stream for 10,000 years almost certainly produced the last Ice Age.
