Hmm; CO2 levels in previous interglacials have been high, but only as high as 310ppm. We are up to 400+ppm now. The last time CO2 was this high was back in the Tertiary, before the ice ages started.
The long term trend for CO2 is downward, and glacial periods will get colder and closer together - but not yet, until the current interglacial is finished.
If we intend to live on Earth for millions of years into the deep future we'll probably need to do some serious terraforming on our own planet; compared to that, this current global climate crisis will seem like child's play.
