200.000 Years Of Climate Change

Ed Hawkins’s Polar Plot animation of warming had a big impact. So I thought I would try the same trick with the 200,000 year record of temperature anomalies from Antarctica measured by the EPICA ice core data. At its peak the Eemian was 3C warmer than the Holocene.

The Epica temperature data for last 200k years. The first rapid warming is the Eemian interglacial followed by the last glaciation and the Holocene. The circle represents todays temperatures. Scale is in degrees C.

The circle represents todays average temperature (1961-1990 normals offset by 10C). Yellow for mean temperature > 4C (-6C) Red for mean temperature >8C (-2C)  and Blue for mean temperature < 4C (-6C).
