Title : Climate change is caused by radio emission of solar flares: Molecular modeling validation based on density functional theory

Abstract:

Atmospheric concentration of about 0.04% carbon dioxide is by no means the main cause of global warming. Climate change can be ascertained according to the Earth's radiation balance. Radio wave radiation (THz, MHz, Radio wave) from sunlight is absorbed by ocean water and silica on the surface of continents, resulting in temperature rise and humidity rise. After sunset, the temperature drops due to radiative cooling caused by low humidity in the atmosphere. These facts can be fully understood by molecular modeling based on density functional theory (DFT/MM).

Biography:

In 2004, Shozo Yanagida retired as a professor of chemistry at the Graduate School of Osaka University and became a professor emeritus. Subsequently, Shozo Yanagida, as a specially appointed professor at the Center for Advanced Science and Innovation at Osaka University, studied molecular association structures of dye-sensitized solar cells and perovskite solar cells using quantum chemical calculations based on density functional theory (DFT) called "molecular modelling (DFT/MM)” was used for theoretical verification. Subsequently, the association molecular structure of polar molecules such as water molecules was analyzed by DFT/MM, and it was verified that the obtained UV/Vis and IR/FIR~radio wave energy absorption spectra agreed well with the measured values.
