That said, the start of every period of falling temperatures and increasing glaciation over the last half million or so years has always occurred when the CO2 was at the absolute maximum in the interglacial that preceded it.
CO2 always increased as the effect of the cause of rising temperature and always decreased as the effect of the cause of decreasing temperature. While the CO2 forcing may stop the onset of another period of glaciation, It has never been equal to this task in recent geologic history.
All forcings aside, though,I'm rooting for the Beach Boys' Endless Summer.
"Always" isn't correct, though when natural conditions are the primary forces at play, this is what one should usually expect. We've rarely had situations where formerly sequestered Carbon was added into the active carbon cycle at the current rates and volumes. And to be truthful, if all we were talking about was a couple of degrees warmer in every season, I wouldn't see much wrong with it myself.
When has always not worked over the last half million years or so?
Take a look at how the red-line of CO2 concentration jumps, at the right side of the graph. You can get over to the right, can't you?
Temperature will be forced up, to follow the radical jump in CO2 and CH4, yet to manifest:

Up goes temperature, up goes sea level, down go O2-respirators, and then jellyfish, algae, and bacteria rule the seas. H2S respirators re-evolve, to live in seas 36 C or hotter.
Humans will devolve.
