When did you start wearing tweed and flannel on a consistent basis this year? About a generation or two ago, these two robust fabrics would have made their first appearance after Labor Day, which marked the natural end of summer fashion. After all, that was the spirit behind the saying “no white after Labor Day,” a rule so sacred among etiquette hardliners that Patty Hearst’s character was murdered for it as punishment in the 1994 movie Serial Mom. But this year, my autumnal clothes have been dashing in-and-out of my wardrobe, with summer pieces continuing to be useful as late as November. Last month, thirteen US federal agencies released a stunning report saying climate change has already had devastating impacts on our health and economy. On a more superficial level, I can’t help but wonder if it’s also affected our wardrobes – and menswear retailing.
Every year, the traditional concept of four seasons seems increasingly outdated. Scientists have found that, as the planet warms up, the tropics have been expanding 0.1 to 0.2 degrees latitude every decade, so that places that once had four seasons are now shifting to having just two. Vox had an article this week about how global warming could change US cities by the year 2050 (“In some cities, it’ll be like moving two states south”). “You can see that Scranton, Pennsylvania, will have a climate that resembles that of Round Hill, Virginia, today,” they wrote. “That’s a distance of about 220 miles as the crow flies, but it means that Scranton will face average summer peaks that are 4.8°F higher and winter temperature lows that are 5.5°F higher.”
This is happening all over the place, not just in Scranton. In parts of New England, winters have warmed at an average rate of more than 1°F per decade since 1970 — that’s more than 4°F total. Last year, some eastern US cities were beset with summerlike temperatures as early as February. And across the US, winters feel shorter and generally milder, with the transition from cold winter weather to warmer spring temps happening earlier. Alexander Stine, an Assistant Professor of Earth & Climate Sciences at Harvard, says: “Once we account for the fact that the average temperature for any given year is increasing, we find that some months have been warming more than others. Most of the difference is the result of this shift in the timing of the seasons, and a decrease in the difference between summer and winter temperatures.”
