Not for decades, and not until well after we stop emitting it.

Correct. My guess is during the 22nd century the downward trend will resume. Then, a whole new set of issues will be faced, and those issues will truly be a humans against or challenged by nature scenario.

Issues which we are probably also now facing.

No they are different issues. Imagine for example, let me pick a number, CO2 at 200 ppm.

The issue has to be a real one before we worry about facing it. CO2 is not going down to 200 ppm at any time within the visible time horizon. If we go back to the emissions that we made before the industrial age, that will be very healthy and there will be no worries about it once the residue of CO2 from the warming is gone.

If there's a natural global cooling trend going on, it will be very gradual, as Nature's cycles usually are. And anyway, by then, even if cooling is as danger, maybe we can resume burning some CO2 to maintain the balance!
