A couple tidbits. I have an old physical sciences book from when I was young. One of things discussed was climate changes. It references various cycles of various periods identified by the Chinese 3000 years ago. Climate cycles all look like sine waves (something common in nature as responses to negative feedback systems always result in sine waves or a combination of sine waves of differing magnitudes and periods). For instance the first sine wave has a period of one year and we now know this is due to the tilt of the Earth's axis causing the seasons of the year. But there were others identified by the Chinese and some of late, they just are no longer taught and in fact covered up by the climate alarmists.
There is another which is 7 years in length (El Nino and La Nina) caused by ocean currents in the mid-pacific and the Central American isthmus. Still another has a 114 year period caused by feedback systems in the sun resulting in solar flare activity changes. Something which has now been modeled mathematically now that we understand solar processes. Still another has a period several hundred years in length due to the precession of the Earth due to angular momentum caused by a less than perfect spheroidal shape (due to the moon). Another not identified by the Chinese is due to the manner in which the Earth's orbit is dictated by the solar winds. Closer to Solaris the concentration of solar winds is greater. So as the Earth dives into a lower orbit the winds push it back out. As the Earth's orbit ascends the concentration of solar winds diminishes and the Earth dives back in ever so slightly resulting in a sine wave cyclic. The Earth can be seen to sort of float on these solar winds.
