A comparison of RCPs and SRES CO2 concentrations. Note that these are CO2-only and do not include the ‘CO2-equivalent’ concentrations. (Data is available at (Note that these curves are for CO2 concentrations not CO2-equivalent concentrations, so will be smaller than the values indicated in columns 2 and 5 of the Table below) Source

The range of atmospheric temperature change predicted by climate models in response to the scenario used in the IPCC AR4 and AR5 assessment reports. The atmosphere has already warmed approximately 1°C since pre-industrial times. (Note that CO2 equivalent concentrations include CO2 concentrations together with the warming potential of other greenhouse gases that have been converted into a CO2 equivalent concentration).

Projected sea level rise (SLR) until 2300. The inset shows an assessment of the likely range of the projections for RCP2.6 and RCP8.5 up to 2100 (medium confidence). Projections for longer time scales are highly uncertain but a range is provided (; low confidence). For context, results are shown from other estimation approaches in 2100 and 2300. The two sets of two bars labelled B19 are from an expert elicitation for the Antarctic component and reflect the likely range for a 2oC and 5oC temperature warming (low confidence). The bar labelled “prob.” indicates the likely range of a set of probabilistic projections. The arrow indicated by S18 shows the result of an extensive sensitivity experiment with a numerical model for the Antarctic Ice Sheet (AIS) combined, like the results from B19 and “prob.”, with results for the other components of SLR. S18 also shows the likely range. source
