You nailed it morphing! Sun’s effect dwarfs any human factors, but if there is a second influence, volcanic ash would be a strong candidate. The Iceland volcanoes spilled thousands if not millions of times as much particulate matter into the atmosphere in a single year as all of human activity ever did. Media ignoring that, of course.
It would seem that all human effort to curtail warming (when it happens) would pale in comparison to increased solar captivity or a Pinatubo or other large eruption.
I understand the control issue, but they are fighting basic intuition and logic IMO.
