The reaction to the polar vortex reminds us it is important to have a citizenry who can distinguish between scientific fact and fiction
The winters of the early 1970s were very cold and snowy in the northeastern United States where I grew up – as elsewhere around the US and Europe. I remember snowfalls that came up to my chin (though, of course, I was only a few feet tall back then). We now call those “old-fashioned winters”, precisely because they have grown so rare as a consequence of – yes – global warming.
If you’re younger than I am (I became a demi-centenarian three years ago), those winters are likely to be outside the range of your experience. And so it may seem plausible to you that cold snaps, that in reality simply reflect the sort of weather that was commonplace just decades ago, might constitute “record” or “unprecedented” cold.
