No, I didn't say that at all.
I did say that we have large interannual variability in area burned. You gave the example of 25 million tonnes of emissions in a year. In years in which we have only 25 million tonnes of emissions, the forests as a whole, including the anthropogenic and natural disturbance components, would be a carbon sink. More carbon dioxide would be removed from the atmosphere.
We have years with low fires, in which our forests overall are carbon sinks, and we have years with large fires, in which the forests can be a carbon source. Of course, many other factors play into this, such as the impacts of insects and other disturbances like the mountain pine beetle.
