I don't think geological records are all that helpful in this case. There has never been a life-form that pushes the pendulum the way humans have. We have done so many things to limit and prevent the natural cycles that would have by now surely led to a significant limitation of the human population.

War, famine, disease, disaster, etc. they have all or are all being limited if not practically being eradicated. The danger is that if you keep pushing and pushing the pendulum the marginal effort needed to push it not only becomes ever greater and the duration which is can be held decreases, but the risk of something causing the pendulum to slip and swing freely exponentially increases. We are approaching several means in which the biosphere that is earth may collapse. We don't even really understand all the finer intricacies of our world, there is absolutely no chance we could even identify some sort of black swan even that we sure as hell won't be able to prevent, let alone reverse.

It all seems to grotesquely stupid how ignorantly we are treating our only habitat. The very single place that we can exist at the moment and we are risking it all on a stupid bet.
