David Grinspoon Quote
Now nearly circular, compared to other epochs, where it is slightly more egg-shaped—we inhabit an interglacial of exceptionally long duration. Models incorporating this fact suggest that, even without us, the ice would not return for another fifty thousand years. In other words, if we don’t screw it up, sending climate careering beyond the safe zone, our luck might hold for quite some time. This warm, stable climate our civilization has enjoyed for ten millennia, and come to take for granted, might last for five times again as long. Yet what about looking farther into the future, beyond just the next ice age? Might we have initiated something more long term? Could we have seriously thrown Earth off its rhythm, perhaps even permanently halting the Milanković cycle of glaciations? My young colleague Jacob Haqq-Misra has been studying this question. Early results from his modeling suggest we may be on our way to initiating such a change in Earth’s behavior.
