There were millennia during the past glacial (when CO2 levels were under 200 ppm) that were as warm or warmer than today.
Four central Europe reconstructions, using collected evidence from disparate biomarkers, indicate there were periods (for example, 54,000 to 51,000 years ago, the Bølling–Allerød interstadial, 14,700 years ago) during the last glacial when temperatures were as warmer than (or similar to) today (Zander et al., 2024).
Temperatures throughout the Holocene (8,000 to 4,000 years ago), when CO2 hovered around 265 ppm, were 3.5°C (and up to 5°C) warmer than today. Modern temperatures are among the coldest of the last 10,000 years.

What do you guys think about the Nikita Zimov experiment in Siberia? I have only learned about it now and I’m still trying to understand how cutting down entire forests and reintroducing big animals helps with anything, but maybe it’s just me and there really is some bigger picture behind his efforts, many people seem to be fascinated by him after all…
