Fermi Resonance and the Quantum Mechanical Basis of Global Warming


Fermi Resonance and the Quantum Mechanical Basis of Global Warming, R. Wordsworth, J. T. Seeley, K. P. Shine

In addition, many comprehensive descriptions of the physics of climate and global warming, including the specifics of the radiative effects of CO 2 doubling, already exist (Pierrehumbert 2011; Wilson & Gea-Banacloche 2012; Zhong & Haigh 2013; Mlynczak et al. 2016; Dufresne et al. 2020; Jeevanjee et al. 2021; Romps et al. 2022; Tziperman 2022; Shine & Perry 2023). For this, the molecular vibrational potential energy U discussed earlier is expressed in terms of dimensionless mass-weighted normal coordinates ζ, ρ, and σ(see Figure 3) and expanded as U= U 0+ U 1+ ..., where is a perturbation parameter. The preceding analysis shows that the value of CO 2 radiative forcing can be understood in terms of the quantum properties of the CO 2 molecule, with the influence of Fermi resonance on the band structure coefficient w particularly critical.
