This study investigated the principal factors governing natural ice melting through controlled experiments near the phase transition temperature (0 degrees C). The process of ice melting plays an important role in understanding glacier retreat and sea-level rise. The experimental results revealed that ice melting is mainly driven by conductive heat transfer from the attached substrate, accounting for 90.62% of the total melting rate, while solar radiation contributes only 9.38%. The study also highlights how rising temperatures intensify heat convection. When the environmental temperature rises by five degrees, the contribution of heat convection increases greatly, resulting in the melting rates of both soil-attached and non-attached ice samples being comparable and convective heat transfer becomes the main factor in the melting of ice. The findings point to a potential link between global warming and accelerated ice melting, with broader implications for glacier retreat and sea-level rise. We performed inelastic neutron scattering experiment as well as first-principles density functional theory calculation of ordinary ice phase, ice Ih. The comparison between the solar radiation spectrum and the vibrational spectrum of ice demonstrated that the main ice vibrational peaks fall far beyond the solar radiation range. This indicates that solar radiation absorption involves non-resonant photon-phonon coupling. Based on the thermal conductivity data of the substances, this study suggests that the photon-phonon resonant absorption (PPRA) photothermal convention method could increase by at least two orders of magnitude than traditional heat conduction method in the field of de-icing efficiency.
