Dry paperbacks packed with VOC will burn like the edge of the paper, as too will dried out reeds when their season is finished, as too will the wet newspaper once it dries out.
Take a look at the fire retardant plants that survived Ash Saturday...the fires went over them and burnt some of the dry edges only.
Take the newspaper test and post your results here.
Which proves what exactly? Yes, if we were to drown the continent we'd have no more fires but that isn't going to happen. australia is a dry continent and it's a dry continent for a couple of very good reasons:
Firstly it's flat, well, not totally but in comparison to all the others it is this means we don't get as much orographic lift happening which causes condensation then causing rain, yes we have rain along the Eastern Seaboard but that's due to the influence of the great dividing range.
Secondly about 15 million years ago the Australian continental plate collided (well, it was at the rate of about 6cm/yr but still significant) with the Asian plate pushing up the Papua New Guinea highlands which serve as a barrier to monsoonal influence, so the whole idea of Australia being some lush rainforest prior to the arrival of humans is just wrong. Yes, Aborigines did have an influence but not to the extent that somer claim.
Now getting back to the fires, I've been through those parts of Victoria on many occassions both prior to and following the fires many of the areas burnt out near Kinglake were wet schlerophyll (for those not familiar with the term it's a rainforest understory with emergent Eucalypts) which under normal circumstances is too wet to burn, however prolonged drought and extreme weather conditions
contributed to a Forest Fire Danger Index of 300, which till then was unheard of. An FFDI over 50
is regarded as extreme, an FFDI of 300 is off the chart. anything will burn in those situations, including rainforest.
The truth is out there.
