I'm wondering how forest fires being a natural thing fit into your viewpoint. I don't think that fact entirely negates your point, but it does seem to dampen it at least.
Trees contain carbon. Burn trees, and they release carbon. New trees end up growing in the ash after it falls and re-capturing carbon. It's a natural, cyclic process.
The problem isn't that humans release carbon or other pollutants (burning trees, coal, oil, etc), it's the scale we do it at, and that we don't automatically re-capture it without doing extra work like planting more trees.
