Nano-scale Radiative Transfer to Solve Large and Mega Scale Environmental Issues

Abstract：

Global warming is one of the most serious problems faced by humans. One method to decrease the Earth’s temperature is to reduce solar irradiation by dispersing nanoparticles in the atmosphere. Submicron-diameter particles or aerosols scatter solar irradiation, whereas they are transparent to long-wavelength infrared radiation emitted by the Earth. It is examined that the first-order approximation of the feasibility of controlling the global temperature without reducing the emission of greenhouse gases. We propose the controlled dispersion of nanoparticles into the stratosphere at an altitude of 30 km.
