Figure-4.9: Connections between global mean and Canadian mean temperature change, and changes in length of the growing season

The left-hand panel shows Canadian mean temperature change plotted against global mean temperature change (°C for 20-year averages relative to 1986–2005) from fifth phase of the Coupled Model Intercomparison Project (CMIP5) model simulations for three different forcing scenarios (green: RCP2.6; blue: RCP4.5; red: RCP8.5). Heavy lines are least-squares linear fits, whereas thinner dashed lines are individual model results. The right-hand panel shows the changing length of the growing season (in days, see Chapter 1, Section 1.2) for warm-season crops in the Canadian Prairies, as a function of changes in Canadian mean temperature.
