The website content challenges the conventional Milankovitch Cycle interpretation, arguing that Earth’s current perihelion (closest solar approach) in January, coinciding with the Southern Hemisphere’s summer, leads to a 7% higher solar irradiance, which oceans absorb, driving a millennial-scale warming trend and polar amplification. Vournas’ analysis suggests that in 10,000 years, when the perihelion shifts to the Northern Hemisphere’s summer, increased insolation on continents (less heat-absorbent t
