(a) Time series of annual mean GMSTs for the past 540 million years. Black line denotes simulated annual mean GMSTs. The red asterisks denote reconstructed GMSTs by Scotese37,38. The black asterisk denotes the annual mean GMST averaged for 1979–2020, using the data from NCEP-DOE Reanalysis 243. (b) Variations of simulated annual and zonal mean surface temperatures for the past 540 million years. Annual and zonal mean surface temperature profiles for (c) 310 Ma and (d) 240 Ma. Red line denotes simulated surface temperatures using CESM1.2.2. Blue line denotes reconstructed surface temperatures by Scotese37,38. GMST, global mean surface temperature; NCEP-DOE, National Center for Environmental Prediction-Department of Energy; Ma, million years ago; CESM1.2.2, Community Earth System Model version 1.2.2.
