Plate tectonics are another huge factor. When Pangea existed there was just one ocean to distribute heat and no polar continent for glaciers to form on and increase the Earth’s albedo. That meant a much warmer planet. The Quaternary glaciation is still ongoing because of those tectonic factors. Another fun fact is that the warmest period in human existence was the Holocene maximum about 8000 years ago[1]. Geology is a fascinating field and thankfully lets us look at climate through a lens that isn’t intensely politicized.
