Change is measured relative to measurements from 1901 to 1950 (black curve). Orange region is the 2001-2100 prediction given the A1B scenario (pCO2 increase to 700 ppm by 2100). Bars to the right indicate the predictions for 2091–2100 for the scenarios B1 (blue bar, pCO2 increases to 500 ppm by 2100), A1B (orange bar, pCO2…
