Figure 12. Observed (green dot) and simulated (box/whiskers) trends in June-August Texas surface temperature (°C/decade). Trends are computed for different beginning years from 1901 (left most box) to 1981 (right most boxes), staggered at 10-year increments, while the end year for all trend calculations is 2010 Thus, the longest trend period is for a 110-yr period (left side), and the shortest is for a 30-yr period (right side). Dark (light) box/whiskers display the CMIP5 (AMIP) simulation trends based on a 20-member (12-member) ensemble. The extreme values of the model simulated trends are shown by the red and blue asterikes.
