I’m on the West Coast of Canada, where temperatures have been unusually cool: 4-5 C below ‘normal’ for weeks now. I used to live in Ontario, where temperature records are currently being blown away: 8, 9, even 12 degrees Celsius higher than the previous record.
Sitting in 6 C and rain sure makes the situation in central Canada look pretty good right now. Rather than 16 C, imagine 24 C – what a great March! However, think about this:
What if records are shattered in the summer by the same amount? For example, rather than a very uncomfortable (Toronto gets very humid) 37 C, what if the temperature hits 47 C? When I grew up in Ontario, very few people had air conditioning because it just wasn’t worth it for three hot and humid weeks in the summer. But 47 C is in another realm entirely.
The extreme temperatures have other consequences, too: thunderstorms – in Spring! – move from unheard of to likely. And how about farmers? There’s a lot of great crop land in Ontario, but a heat wave of 47 C will kill almost everything currently commercially grown. One week of weather like that could cost the entire Ontario crop.
We’re in for it now; the amount of greenhouse gases in the atmosphere mean that weather extremes are the new normal. Let’s see how we ‘adapt.’
