During typical interglacial periods, sea levels peak at about twenty feet or so above current levels when CO2 levels remain at typical levels. This would've occurred for us except for the Younger Dryas climatic event from 12,900 to 11,700 calendar years ago suppressing long term temperature increases.
What we need to consider in regards to this interglacial period is the fact that we have artificially increased the CO2 levels to the point that they will counter overwhelmingly any benefit that the Dryas mini-ice age event gave us.
Note: Global sea level was 120 meters lower at the peak of the last ice age 26,500 years ago.
