I would have liked an estimate of the natural sources to compare.

  It's in section 3.3. - Natural Al estimated at 141.1 metric tons / year not varying. - Human-made: 2016: 5.36 tons, 2022: 41.7 tons, "future" could be 912 tons, i.e. more than 6x natural. I think the last figure is based on many planned large satellite constellations being deployed.
