The observed mean global surface temperature has increased 1.2 ℃ above pre-industrial values along with an increase of atmospheric carbon dioxide (CO2) above 400 ppm last seen millions of years ago when sea-levels were 20 meters higher. A causal link between the rising global temperatures with accumulating atmospheric greenhouse gases is established using a simple no-feedback radiative model and shows changing CO2 concentration is the dominant driver. Extrapolating fits to temperatures and CO2 observations on a “business-as-usual” basis yields an additional 0.32 ℃ temperature rise in 20 years with CO2 doubling to 556 ppm in 31 years and suggests an equilibrium climate sensitivity of 3.4 ℃. An aggressive pursuit of carbon replacement and sequestration strategies is recommended, employing limited solar geoengineering in the polar regions if necessary to limit further erosion of ice-shelves. Policies should be rendered, not only to achieve net-zero goals, but to reduce CO2 levels below 400 ppm to avoid risking an otherwise inevitable and dramatic sealevel rise.

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.
