The original article was published with errors which are corrected below. In Fig. 5, there was a mistake in the calculation for the variance due to small sample size. The original figure should be replaced by the following figure (Fig. 5).

(upper) Kuroshio net transport [Sv] in the present climate (1986–2005) and at the end of the 21st century (2081–2100). (a) Kuroshio net transport. The vertical black line is the standard deviation of the estimate. (b) Variance of the Kuroshio net transport. The unit of variance is the square of the transport in Sv. V: internal variation, M: variance among models, B: variance due to small sample size. (lower) Same as (a–b) but for the KE latitude [°] in the present climate and at the end of the 21st century. (c) KE latitude. The vertical black line is the standard deviation of the estimate. (d) Variance of the KE latitude. The unit is the square of the latitude in degrees. V: internal variation, M: variance among models, B: variance due to small sample size
