Table 2.

Analysis of variance (ANOVA) results for comparisons of mean monthly air temperature and square root-transformed precipitation from Puget Sound regional climate model outputs. Effects were decade (1970s vs. 2050s), month (December, January, February), climate model (ECHAM5 vs. CCSM3; see text for details), site (Skagit, Hamma Hamma, Nisqually), and interactions. Statistically significant factors are in bold. The r² values indicate the total variation in the monthly means explained by the model.
