Air temperature

British Columbia is expected to experience more warming than the global average [70,71]. Even though air temperature is moderated by the ocean, air temperatures are projected to increase by 1.8°C by the 2050s and 2.7°C by the 2080s, and could reach of 3-5⁰C by the end of the 21st century if emissions continue at current rates [70–72]. On average, air temperatures are likely to increase by 0.1-0.6⁰C per decade [73].

The summer growing season is projected to lengthen and frost-free days to increase by 20-30 days by 2050-2080 [73] (see MaPP region Summary Table). Winter minimum temperatures across BC may increase by 4-9°C by 2080, and summer maximum temperatures may increase by 3-4°C [70,73].
