Important future predictions include global average temperature and radiative forcing. You can find summaries of these predictions from AR5 below.

Here the IPCC gives us the latest graph of all their models with their future projections for global average temperatures. See figure 12.5 (AR5 Section 12.4.1.1 Page 1054)

Here the IPCC shows a graph of all the models and their future projections for radiative forcing. See figure 12.4 (AR5 Section 12.3.3 Page 1053)

When it comes to predicting future temperatures, the IPCC downplays this ability from AR4 to AR5.

For example, in AR5 the IPCC states if the upper temperature predictions of 5°C are correct then by the end of the century this means the earth will see the same temperature change as seen at the end of the last ice age. (AR4 FAQ 6.2 Page 465)

The IPCC goes on here to state there is no evidence of any comparable rapid increase in global average temperature in the last 50 million years. (AR4 FAQ 6.2 Page 465)

However, in AR5 this changes some with statements like here where the IPCC admits there is an ‘uncertainty range’ when it comes to predicting temperature because uncertainties combine with natural year-to-year climate variability (AR5 FAQ 1.1 Page 140)

Today, in AR5 the IPCC presents a table of predictions of temperature and sea levels change seen throughout all the IPCC reports. (AR5 Table 1.1 Page 124)

The IPCC claims observations are within in range of the IPCC models including average global temperature and sea level rise as their models have advanced. (AR5 Executive Summary Page 121)

Over time it is important to track model’s performance on such predictions as the IPCC notes it is to evaluate model’s performance. (AR5 Section 9.1.1 page 746)
