Table 4 Changes per year and trends of the Frost Days (FD), Summer Days (SU), and Ice Days (ID) for observed (1989–2014) and two future periods: FP1 (2026–2050) and FP2 (2051–2075), under two shared socioeconomic pathways SSP2-4.5 and SSP5-8.5.

From: Future projections of temperature-related indices in Prince Edward Island using ensemble average of three CMIP6 models
