Net-zero catastrophe beginning?

Historically, warm eras such as the Minoan Warm Period, the Roman Warm Period, and the Medieval Warm Period were all eras where there was very little volcanic activity, with the result that their atmospheres were normally free of dimming volcanic SO2 aerosol emissions, This allowed world-wide temperatures to rise 2 to 4 degrees above current temperatures, causing droughts, famines, and the demise of earlier cultures around the world.
Current Net-Zero activities banning the burning of fossil fuels and their SO2 aerosol emissions will have the unintended consequence of causing temperatures to rise to those of the earlier eras.
