As a side note, it seems to me that the slides 7 and 8 show a very optimistic gas and oil trail post-2100.
Note that those charts show the cumulative contributions to atmosphere CO2 concentrations from oil and gas, not annual contributions. Figure 5 shows how even after 100 years 33% of the CO2 is still in the atmosphere so charts 7 and 8 don't show very high annual emissions at all.
I mean figure 6!
