Well, not propaganda but rather thoughtful analysis of geologic observations.

To declare volcanism to be a contribution to climatic cooling is not propaganda. After the cooling dissipates, warming caan occur.

Assuming the models of "greenhouse gases" causing "global warming" have any validity, a fairly good sized volcanic eruption will dump far more "greenhouse gas" into the atmosphere than mankind will. But on the other hand, volcanoes also have the effect of replenishing the atmosphere. No molten core, no volcanoes, no atmosphere, no life.

Did not read the article...but what you said is actually correct.

Volcanoes..have caused changes in the world's climate..probably more than man has.
