This presentation is the result of personal experience. In the fall of 2007, following a conversation held on a forum of astronomy, where the role of the Sun in the climate was mentioned, I decided to dig into the reality of anthropogenic global warming, in which like many people, I really believed.

After much research, many discussions with experts on the subject, I discovered that scientific consensus did not exist in this area, and that the theory of global warming of human origin was very questionable.

The global temperature of our planet has warmed, roughly since the end of the 0,74th century. The official figure of the IPCC is + 1906 ° C between 2005 and 2. This is a fact, apart from measurement errors, but it is not a new fact, because the climate has often changed in history. of our planet. We are told every day in the media that this is the result, this time around, of the greenhouse effect caused by COXNUMX resulting from human industry.

In this presentation, I endeavor to show the scientific reasons which, according to the many skeptical climatologists, do not stick with this thesis.

I do it without animosity because I do not believe in a conspiracy or a system of deliberate disinformation in this matter.
