In this work, we examine the impact of increased anthropogenic emissions on equatorial plasma bubble (EPB) occurrence by modeling the growth rate of Rayleigh-Taylor (R-T) instability (), which is closely related to EPB generation. Using the GCITEM-IGGCAS model, is calculated under three different CO2 emission levels. As CO2 increases, significantly increases at low altitudes (<∼260 km) and decreases at high altitudes (>∼320 km). In the altitudes in between, increases (decreases) before (after) midnight. Longitudinal variability of the change is manifested apparently above ∼280 km, while it is insignificant for low altitudes. Term analysis revealed that changes in the gravity term and the electric-field term are the main causes and that the neutral-wind term is insignificant. The investigation indicates that increased anthropogenic emissions can change EPB occurrence and, in turn, the radio-communication system and therefore influence modern technological systems, which is expected to be more serious in the future.
