Has anyone been able to find out where we are in that cycle now? There was a mass extinction that occured 70,000 years ago, as identified by human DNA research. Could it have been the apex of the cycle?
that one occured at the same time as the last super valcano eruption, which was proven to have lowered the temperature a lot.

edit: sorry sam, i did not see that you posted about this.

the more man learns, the more he realises, he really does not know anything.
