These climate models suggest that depending on our GHG emissions the global surface temperature could, by 2081–2100, rise between 1.3°C and 5.5°C compared with the pre-industrial period (1850‒1900): see Table 3. In all the scenarios except SSP1–1.9, a global temperature rise of over 1.5°C is reached between 2021 and 2041 with the best estimate being 2030.
