Plots of land surface temperature by bioclimate CAVM subzones show a clear separation of temperature within the different zones. a The non-standardized data. Subzones A, B, D, & E have statistically significant increasing trends as indicated by an asterisk in the legend (p values 0.001, 0.039, 0.026, and 0.010, respectively). Disregarding the absolute differences, the standardized plot (b) more clearly shows the common shifts in rates and directions of change as well as differences among subzones. CAVM subzone A, the northernmost zone, showed the greatest rate of overall increase in land surface temperature, followed by subzones E, B, and D
