CO₂ and Temperature in the Holocene

Default view intentionally mirrors the widely-shared chart style: black temperature line labelled Vinós 2022 and blue Monnin 2004 CO₂ line. Use the toggles/legend to reveal comparison series.

Replication mode. The chart opens in a visual configuration meant to match the social-media graphic: only the Vinós 2022 temperature reconstruction and Monnin 2004 CO₂ are shown by default.

Method summary (from the replication guide). Vinós’s temperature line is reconstructed from Marcott 2013 proxy sheets: per-proxy anomaly → 20-year bin stack average → Z-score → rescaled to a target HCO–LIA gap. The Monnin line is the EPICA Dome C Holocene CO₂ record.

Comparison layers. The legend can reveal the same reconstruction at native scaling (×1), Marcott Standard5×5/RegEM stacks, and post-1800 instrumental extensions. This keeps one chart for both replication and QA checks.

Two y-axes. Temperature (°C anomaly vs 1800–1900) on the left; CO₂ (ppm) on the right.
