Adapting to Extreme Heat Events: Guidelines for Assessing Health Vulnerability

Figure 2: Historical and projected number of hot days and warm nights for selected cities in Canada

Two bar charts show the number of hot days and warm nights, respectively, for seven Canadian cities (Fredericton, Montreal, Kingston, Toronto, Hamilton, Windsor, Winnipeg). The numbers are based on the observed temperature data between 1961 and 2000, and projected for 2011-2040, 2041-2070 and 2071-2100 using Canadian climate models (Scenario A2).

Bar chart for hot days above 30°C/86°F reads:

• 1961-2000: Fredericton = 9, Montreal = 9, Kingston = 4, Toronto = 13, Hamilton = 15, Windsor = 22, Winnipeg = 14
• 2011-2040: Fredericton = 16, Montreal = 18, Kingston = 9, Toronto = 28, Hamilton = 24, Windsor = 35, Winnipeg = 30
• 2041-2070: Fredericton = 24, Montreal = 27, Kingston = 15, Toronto = 48, Hamilton = 36, Windsor = 48, Winnipeg 35
• 2071-2100: Fredericton = 40, Montreal = 44, Kingston = 32, Toronto = 59, Hamilton = 56, Windsor = 64, Winnipeg = 58

Bar chart for warm nights above 22°C/72°F reads:

• 1961-2000: Fredericton = 0, Montreal = 2, Kingston = 3, Toronto = 2, Hamilton = 2, Windsor = 5, Winnipeg = 2
• 2011-2040: Fredericton = 1, Montreal = 6, Kingston = 10, Toronto = 5, Hamilton = 4, Windsor = 10, Winnipeg = 3
• 2041-2070: Fredericton = 3, Montreal = 10, Kingston = 17, Toronto = 7, Hamilton = 7, Windsor = 22, Winnipeg 4
• 2071-2100: Fredericton = 4, Montreal = 22, Kingston = 32, Toronto = 22, Hamilton = 19, Windsor = 40, Winnipeg = 8
