defined as T(t) - T(1750).
The results corresponding to the crepuscular (when the peak is reached) and
stabilised atmosphere are presented in Table 10.3.
It is important to note that for the three emissions scenarios presented, there
appears to be a greater consensus as to when the exhaustion of fossil fuels will occur
(150 to 300 years) than for the CUE, which varies sevenfold. Nevertheless, the effect
of this difference on the climate is much more significant, since peak atmospheric
CO 2 could reach values of around 6,000 ppm, causing a peak warming of about
12.3 o C. The effects into the long term are also significant since atmospheric carbon
dioxide in the stabilised atmosphere might be higher than 3,200 ppm, whilst the
