According to [1] we are already way beyond the temperatures of the medieval warm period. So not sure your argument holds. Also, apparently this effect was localized, not global. I guess there is no one disputing that Earth climate is driven by multiple sources, so that’s not the point. The question is: are we driving climate change to a large enough extend that we could have an impact on it by changing what we do? And the consensus seems to be a strong yes. The other question is: is climate change a net negative? And again the answer seems to be a strong yes.
