Climate-denying rumor propagation in a coupled socio-climate model: Impact on average global temperature

immediately but slowly dissipates, and the temperature decreases gradually as the CO2 level decreases. Even though the population starts to act immediately, it takes more time to see a change since it takes more time to dissipate the CO2 and even more time to see a drop in temperature. To understand the influence of the emission limiting strategies considered by the rejectors in the population on the temperature anomaly, three scenarios are identified: a best-case sce- nario, which will be an ideal case where the temperature levels stay below the IPCC proposed levels [4], an average-case scenario, where the temperature increases little above the proposed level and a worst-case scenario, where the temperature increases far above the proposed level.

(a,d) Times series showing the rumor dynamics for baseline parameter values (b,e) Time series of emission scenario (GtCO2yr-1) and (c,f) temperature anomaly (˚C) for baseline parameter values. (a,b,c) is the time series for the baseline parameter value and (d,e,f) is the time series plot generated using the accepted parameter values after applying ABC. Each of the multiple lines in (d,e,f) is a time series generated using each set of parameter values that were generated by ABC. https://doi.org/10.1371/journal.pone.0317338.g001 PLOS ONE Climate-denying rumor propagation in a coupled socio-climate model: Impact on average global temperature PLOS ONE | https://doi.org/10.1371/journal.pone.0317338 January 16, 2025 7 / 18
