How did the annual global temperature anomaly change from 1905 to 1920 (°C relative to 1951–1980)?
This is a real historical chart. Extraplot shows you the beginning and asks you to draw what happens next, then reveals the actual line. Below is the full series with the reveal point marked.
Solid line = visible part you would draw from · dashed violet = the actual revealed data after the cutoff.
The reveal
After the cutoff (1911), the actual values were:
| Date | Actual value |
|---|---|
| 1912 | -0.37 |
| 1913 | -0.34 |
| 1914 | -0.15 |
| 1915 | -0.14 |
| 1916 | -0.36 |
| 1917 | -0.46 |
| 1918 | -0.3 |
| 1919 | -0.27 |
| 1920 | -0.27 |
