In times of the European Medieval, the powerful contemporaries and influencers propagated the geocentric model of the world according to which the Earth should have been located in the centre of the Universe and the Sun and the planets should have circumnavigated the Earth. A modern analogue is the current superstition that the human is provoking and can control the climate change by the anthropogenic emission of carbon dioxide.

This book presents examples of continuous natural climate changes, such as the development of the temperature of Earth's atmosphere, the oceans' sea levels and the ice volumes of the last few millions of years. These are explained and discussed, presenting data from different scientific areas such as geosciences, archaeology and astrophysics.

Hereby, we will see that quite complex astrophysical and heliophysical mechanisms cause the periodically recurring long- and short-term variation of climate which cannot be influenced at all by any human being, also not by any increased or reduced emission of anthropogenic carbon dioxide. Controlled by the Sun's energy reaching the Earth's surface, the oceans are the global player interacting with the atmosphere and dominating its temperature.

It was intended to write this book in an understandable style for everybody interested to learn more about the controversially discussed topic of climate change, or who is affected by the drastic measures of policy and want to form their own opinion. On the other hand this publication wants also to be a compact base and reference for the scientific young generation to invite them to immerse themselves into this very interesting and exciting field of natural sciences.
