a–l, The slope of the linear trend of annual-mean UTI and WUI (a–h) and coastal UTI and WUI (i–l) during 2006–2100 for the CESM-H ensemble mean (a–d,i–l) and CMIP6 CGCM ensemble mean (e–h) in the CalCS (a,e,i), HCS (b,f,j), CanCS (c,g,k) and BCS (d,h,l). The error bars denote the 90% confidence interval for the slope. The right axes measure the values of UTI and WUI trends divided by the integration area. The sample size (the number of time records used to derive the confidence interval) is 95.
