Figure 3 : Summary of constrainable lead times and increases in precision.

From: Predicting future uncertainty constraints on global warming projections

Figure 3

Color shading indicates increases in precision (%) for each year of updating (horizontal axis) and target of prediction (vertical axis) from (a) RCP2.6 to (d) RCP8.5. Predictions below and right of the black lines are constrainable according to our threshold for accurate prediction. (e) How many years in advance we can predict the true timing of exceeding the 2 °C and 3 °C warming thresholds. Blue and red bars show the normalized histograms for the 2 °C and 3 °C warming thresholds under RCP8.5, respectively. Triangles indicate the median values.
