Thus, pathways with lower rates of emission in 2050 are likely to result in a similar amount of peak warming, while higher rates of emission in 2050 can lead to varying levels of peak warming, as seen in figure 2d.

As in Lowe et al. [33], we find that emissions in the year 2020 are not a good indicator of peak warming, because they are largely a function of current emissions, and are not a key determinant of cumulative emissions.

Based on the metrics presented in figure 2, we conclude that, for cases with no emissions floor, the strongest correlation across all pathways occurs between peak warming and the cumulative emissions from pre-industrial times to the time of that peak warming, as shown in figure 2a.

We consider other emission metrics, such as the emissions in year 2020 and 2050, and find that these cause a much wider range of magnitudes of resultant peak warming than metrics based on cumulative carbon emissions to the time of peak warming.

The type of cumulative emission metric varies between the plots: cumulative emissions to (a) 2500, (b) the time of peak warming, (c) 2100, and (d) 2200.

Those trajectories considered here that do not peak near 2200 have all warmed to within a small fraction of their peak warming by this date, and therefore the emissions emitted in these pathways after 2200 only serve to maintain temperatures, and not to induce more warming.

This phenomenon is illustrated by the lowest yellow curve, which peaks in 2273, but has warmed to 99 per cent of its peak warming by 2200.

The correlation is almost as strong if cumulative emissions out to 2500 are considered (shown in black squares in figure 3a) because the vast majority of the emissions in these zero emissions floor pathways have occurred by the time of peak warming.

We show in figure 2 that cumulative emissions to the time of peak warming are tightly correlated with peak CO2 - induced warming for the case with no emissions floors, and here we investigate whether emissions floors affect this correlation.

We also find that, for large cumulative totals in particular, cumulative metrics based on integrations over smaller time periods, such as 2010 — 2050, do not correlate with peak warming as well as cumulative emissions to a given date near the time of peak warming.

Figure 3b shows peak warming plotted against cumulative emissions integrated between the year 1750 and the time of peak warming.

If the cumulative emissions over the duration of the floor are a large fraction of the cumulative total, then the level of the floor is a crucial determinant of peak warming.

This occurs because the cumulative totals include contributions for portions of the emissions floor that are emitted after the time of peak warming, which can have no effect on peak warming, as illustrated by the green curves in figure 1.

We consider cumulative carbon emissions (i) from pre-industrial times to the time of peak warming and (ii) from year 2010 to year 2050.
