The last million years had comparable temperatures, you'd need to go back to 50 Myr ago to have a significantly warmer climate, and without inland glaciation anywhere on Earth.
- tomp 1y agoI’ll trust Wikipedia on this topic. > The Last Interglacial climate is believed to have been warmer than the current Holocene. > During the northern summer, temperatures in the Arctic region were about 2–4 °C higher than in 2011 https://en.wikipedia.org/wiki/Last_Interglacial https://en.wikipedia.org/wiki/Last_Interglacial
