Ice doom of DOOM!


The previous ice age lasted some 110,000 years and ended about 11,000 years ago. In other words, some 4,000 generations of humans knew of nothing but harsh winds and eternal snows. The apparently "normal'' periods between ice ages, like the present one, have averaged between 8,000 and 12,000 years. In short, the next ice age is overdue. The key question is when it will come. Can space be colonised by a sufficiently large population so that, when the next ice age strikes, it will not threaten the survival of the race?

I'm going to come right out and say it - the "4000 generations of humans" line is because he consciously or unconsciously considers that the only actual "humans" are the ones who come from a specific geographical region.
