Query: Advanced testing of low, medium and high ECS CMIP6 GCM simulations
  versus ERA5-T2m   The equilibrium climate sensitivity (ECS) of the CMIP6 global circulation
models (GCMs) varies from 1.83 {\deg}C to 5.67 {\deg}C. Herein, 38 GCMs are
grouped into three ECS classes (low, 1.80-3.00 {\deg}C; medium, 3.01-4.50
{\deg}C; high, 4.51-6.00 {\deg}C) and compared against the ERA5-T2m records
from 1980-1990 to 2011-2021. We found that all models with ECS > 3.0 {\deg}C
overestimate the observed global surface warming and that spatial t-statistics
rejects the data-model agreement over 60% (using low-ECS GCMs) to 81% (using
high-ECS GCMs) of the Earth's surface. Thus, the high and medium-ECS GCMs are
unfit for prediction purposes. The low-ECS GCMs are not fully satisfactory yet,
but they are found unalarming because by 2050 they predict a moderate warming
($\Delta T_{preindustrial\rightarrow2050}\lesssim2\:{^\circ}C$).
