    The fires are a HUGE increase ( jump actually ) in burning acreage even for Canada. That's quite a lot of lost carbon sequestration for decades, and quite a lot of GHG emission with atmospheric persistence lasting for centuries. If it was just Canada,
    that would be one thing, but when it's happening all over the world, you have a serious problem on your hands.

    But not a lot of extra CO2 in the atmosphere. It certainly hasn't swamped the usual seasonal variation.

    As an Australian, I guess I'm obliged to present the Cape Grim data as well. The latest number there is for this July, when Canada was already burning with some enthusiasm.

    The long-term average of trees burned is a constant fraction of trees
    grown. The scientific principle is called "conservation of carbon."

    Humans change the fire duty cycle.

    From that point of view we don't care whether the tree burn or rot. They end up a CO2 in any event. The carbon tends to be tied up in a tree for longer if the tree lasts long enough to rot.

    Humans change the fire duty cycle.

    So do quite a few more natural effects.
