File:ALICE SPRINGS on global climat changes.gif

The graph shows that in the past three centuries, in contrast to many opinions on this subject, there is no correlation between the quantity of CO2 (carbon dioxide) emissions caused by human industrial activity and the intensity of global coolings / warmings of the Earth's surface.

The most intense period of global warming was in the eighteenth century, when industrial activities almost non-existent.

Global coolings, which began on Earth at the beginning of the nineteenth and at mid-twentieth century were not correlated with retrogressions of industrial activity, which could reducing the amount of burned coal and CO2 emissions at that time.

The only positive correlation in this case is the relationship between the development of the average temperature of the Earth's surface and the intensity of solar radiation corresponding to changes in turn the average number of sunspots (called the Wolf number).
