Once we have used real observations to understand the probability in the historical record, then we can use climate models to compare the probability in the current climate (in which global warming has occurred) with a climate in which there was no human - caused global warming.

Overall, this results in an impressively small model spread around observations over the historical record and a relatively constrained spread for each of the individual future projections.

Projections of future summer mean WBGT under the RCP8.5 emissions scenario that are constrained by observations indicate that by 2030s at least 50 % of the summers will have mean WBGT higher than the observed historical record value in all the analyzed regions, and that this frequency of occurrence will increase to 95 % by mid-century.

Climate sensitivities estimated from recent observations will therefore be biased low in comparison with CO2 - only simulations owing to an accident of history: when the efficacies of the forcings in the recent historical record are properly taken into account, estimates of [Transient Climate Respons — TCR] and [Equilibrium Climate Sensitivity — ECS] must be revised upwards.

Some are developed based on mathematical models, some from looking at historical records, some from other observations of the atmosphere.
