Fig. 6

Top row: Change in the frequency of daily maximum temperature extremes as the ratio of the 2071–2100 and 1961–1990 periods, using 1961–1990 as fixed baseline for the a uncorrected and b corrected cases. Ratios above Γ—10 are highlighted in purple as they are only possible due to the bias in the historical period. c Bias in the extreme frequency change relative to the corrected case. d Same as c but restricted to the extended summer season and with an additional 3-day persistence criterion. To highlight changes on land, ocean grid cells are masked for this case. Intermediate steps for d are shown in Fig.Β S7.
