> If the last 10,000 years of relative climate stability is unusual--and it seems to be at least within the context of the last 100,000 years--then how can you argue it's "bad for life"?

Edit: I'm not arguing that 10k years of climate stability is bad for life. The opposite, actually.

I don't really think that the climate of 100,000 years ago matters too much, aside from the fact that our species (and those we rely on) survived. The critical difference is the last 10,000 years of relative stability is the period during which human population reached billions. I'm sure we can survive a return to inclement weather, but we probably won't thrive.
