All you have to do is look at the level of air pollutants on the Chinese East Coast to look past that particular statement

OK, slight exasoration with the northern hemisphere, but at least for europe.
Otherwise, the volcano in Iceland wouldn't have had an effect if it's already that bad anyway.

Volcano emissions have always been an established part of the ecology, whether the carbon they produce has a direct effect on the climate system, or if it's absorbed by forests and whatnot
Excepting most of the forests are now down, to be replaced by pasture land for domesticated animals to be adding further pollutants via methane gas emissions. Chuck in our reliance on oil and it's just not very good all round. An unsustainable 10.5 billion people by 2050, aint too clever either.
