When the mercury soars it’s a heat “wave” or heat “dome.” When it plunges it’s a cold “snap”. As in, a temporary blip, nothing to see, doesn’t mean a thing. Such as Scientific American: “This week’s cold snap across the U.S. will be one of ‘the most impressive Arctic outbreaks of this century,’ one climate scientist says”. And the one in Texas in February 2021? Also a “snap”. And “More daily weather records fall on Vancouver Island amid cold snap”. But after a week it sure feels like a cold dome.
To give them credit, partial anyway, they also say: “Scientists are still trying to pin down precisely what causes these disruptions” and quote “Kristina Dahl, a climate scientist at the Union of Concerned Scientists”, that:
“It’s a very active area of research and something that scientists are passionately debating and trying to figure out at the moment. It’s definitely not settled science.”
And then go right back to the guy they started with who says otherwise:
“Still, many experts believe climate change likely plays a role – and Cohen goes even further: he contends that climate change in the Arctic is directly disrupting the polar vortex…. ‘It seems very counterintuitive and surprising that a warmer planet can actually increase your odds of experiencing severe winter weather events – but that’s what our research has shown,’ Cohen says.”
But computers to the rescue:
“Megan Kirchmeier-Young is a research scientist with Environment and Climate Change Canada who uses climate models to figure out whether certain extreme weather events can be linked to climate change.”
“‘In general, cold extremes are becoming less frequent,’ she said. Not only that, but the temperatures during cold snaps are becoming warmer.”
Hey. Didn’t you say we Canadians just set a bunch of records for cold rather than having warmer temperatures in our cold “snap”? But it’s far worse to dismiss mere cold records as mere factual evidence so pay it no mind:
“In fact, the record temperatures we saw in recent weeks would ‘most likely’ have been even colder without climate change.”
How do you know? Because it’s getting warmer. And how do you know it’s getting warmer? Because the cold snap would have been snappier otherwise.
That argument is frustratingly circular. So, care to help us out by making a prediction about future reality we can actually test? Uh, that’d be not:
“‘As we continue warming, it is less likely that we will be breaking cold records,’ she added, ‘but we may.’”
Fortunately since all evidence confirms the theory, it doesn’t matter anyway. The science remains settled. Whatever happens, warming explains it, and moreover whatever happens, it proves the planet is warming. Even cold weather. AP, for instance, assures us that:
“Much of the United States is shivering through brutal cold as most of the rest of the world is feeling unusually warm weather. However strange it sounds, that contradiction fits snugly in explanations of what climate change is doing to Earth, scientists said.”
What opinion they might have had of public utilities in Canada begging people to shut off everything including the oven and of all things do not even think of charging your marvellous reliable EV the story did not explain. The Weather Network did headline it “A once in a generation cold is taking ahold of Western Canada” but no scientists were marshalled to say such events were becoming far more common, as would have been obligatory if a once in a generation heat arrived.
