Synthesized in this paper are published geological, paleoclimate, archaeological, and genetic findings to evaluate hypotheses linking long-term Earth evolution with opportunities and constraints for human cultural development and dispersal. Presented here are phanerozoic CO2 and temperature, tephrochronological evidence for the Kikai-Akahoya eruption, and ancient NA and obsidian provenance studies relevant to Jomon period mobility. The atmospheric CO2 content had decreased to the lowest level of about 0.02 % over the last 420 million years by around 20 thousand years ago well before humans started to use fossil energy in a large scale, possibly increasing the atmospheric CO2 level. Antarctica moved to the South Pole and started accumulating ice around 35-40 million years ago to become the largest ice reservoir and a buffer to control the sea level by accumulating more ice at higher atmospheric temperatures. The Kikai-Akahoya eruption around 5250 BC could have forced some Jomon people to emigrate westward from the southwestern Japan, possibly as far as Middle East, forming Sumerian and Israeli cultures and bringing them back to Japan. Preservation of such ancient cultures and genetic information to date may have been possible only in geographically isolated locations such as Ethiopia, Tibet, and Japan.

Journal of Hyojeong Academia aims to serve as a global platform where researchers and scholars of various disciplines can contribute ideas for our sustainable global community of Co‐existence, Co‐prosperity, and Co‐righteousness. The journal is a multidisciplinary, open‐access, internationally peer‐reviewed
academic journal, and it invites all areas of research conducted in the spirit of post materialism including studies centering on God, studies unifying religions and
sciences, and studies on all aspects of Co‐existence, Co‐prosperity, and Co‐righteousness.
