I've been looking at some recent research comparing glacial and interglacial periods — specifically the Eemian and the Holocene. The Eemian was warmer than the Holocene, and the cooling trend since then is more pronounced in the last 11,000 years. A 2023 study in *Nature Climate Change* looked at ocean sediment cores and found a gradual cooling trend, especially after 8,000 years ago. It's not a sharp drop, but the overall direction is downward. The warming of the Holocene was a temporary anomaly compared to the long-term glacial cycle.
