Abstract

The present study describes the alternation of periods of global warming with periods of global cooling at planetary scale. As our planet travels through the universe spinning around the Sun, the solar disk also spins around the Sun making one change of zodiac sigh at about 2000 years. For 12 zodiacal signs a complete cycle is made at 24000 years. Today our data show the temperature it’s at its peek of the last 10000. Since we know 10000 years ago it was colder, the phenomenon which describes this change is the presence of the solar disk in the plane of the movement of the Sun around the centre of galaxy. Sun leaves behind it a trace of thermal heat and when planets spin they accumulate part of this heat when they pass behind the Sun, loosing it when they move in front of the Sun facing the cold from the universe. But as the solar disk moves, in the same time with the Sun, when this angle becomes high enough, all planets no longer pass behind the Sun and they no longer accumulate thermal heat, so the temperature of our planet becomes lower. After a complete cycle of 12 zodiacal signs (24000 years) the temperature of the planet is the same. Periods of global warming and global cooling are a natural phenomenon which repeats itself at every 24000 years. On long term, as in our universe we have 3 types of rotations, the consequence of each one is the following:1st rotation, the planets spin in the solar disk. For Earth we have spring, summer, autumn and winter with a period of 1 year. 2nd rotation, the solar disk spins around a line which connects Sun and centre of galaxy. For Earth we have global warming and global cooling with a period of 24000 years. 3rd rotation, the solar disk spins around an axis perpendicular on the galaxy plane. For Earth we have a period of continuous warming lasting hundreds of thousands of years followed by periods of global warming and global cooling, with a total period difficult to be defined.
