> climate change weakens the jetstream... this is a symptom of something much larger. I don't like being downvoted when I'm right, so here are some sources for those doubting my comment. The cold in western Canada is from a Polar Vortex, https://www.cbc.ca/news/canada/british-columbia/polar-vortex-explainer-1.7082446 https://www.cbc.ca/news/canada/british-columbia/polar-vortex... Watch the video and they explain how polar vortex's occur from a breakdown in the usual jetstream and experiencing polar vortex's in el nino years is strange. And an article about the jetstream changing (becoming 'wavier') as a result of climate change, https://www.sciencedirect.com/science/article/abs/pii/B9780128215753000153 https://www.sciencedirect.com/science/article/abs/pii/B97801... So, yes, Calgary gets cold. But this year is also not normal.
