Summary
The graph shows that in the past three centuries, contrary to many opinions on this subject, there is no correlation between the quantity of CO2 (carbon dioxide) emitted by human industrial activity and the intensity of global cooling / warming of the Earth's surface.
The most intense period of global warming was in the eighteenth century, when industrial activity almost did not existed.
Global coolings on Earth began in the beginning of the nineteenth and in midle of twentieth century were not correlated with retrogressions of industrial activity, which could cause a reduction in the amount of coal burned and CO2 emissions in those periods.
The only positive correlation, in this case, is the relationship between the average temperature of the surface of the Earth and the Sun activity measured as the intensity of observed changes OF the average sunspots number (the Wolf number).
