In all my years I have never experienced such pollution. We have had 2 years of extended dry weather in Tasmania (from November through to April) conicident with huge increase in forestry burnoff in the north of our state. Take a look at the whole picture then make a conclusion.

I am not sure how GW specualtion relates to burnoff, except both are caused by too many people using too much of the Earth's rescources. Of course, our ecology has evolved to some extent to need burn off, and during some atmospheric conditions it will hang around. I suspect the forestry industry knows this and when felling timber burns the area to allow germination of the next generation of trees. This would make it a sustainability practice.
There was a previous premier of Victoria who claimed that pollution was not a problem because Melbourne was a windy city. Fortunately we live in more enlightened times.
