Okay, now it’s cold. Those of you who recall my Winter Biking post know I delivered newspapers as a kid, and that my parents had a rule that if it were colder than -20 degrees F, I could get a ride on my paper route. I decided to keep that rule as an adult, and ride my bike to work as long as the temperature remained above -20.
I broke that rule this week. Bus service isn’t great on Saturdays, so I rode to work. This is what -21 degrees F (-30 C) looks like. The fog on the lenses is from bending over to lock my bike. I was able to see better than that while riding. I am happy to say that my new Bontrager Old Man Winter boots kept my feet warm(ish) with just dress socks. Now that I’ve tested them, I’ll wear warmer socks next time.
This was the first time it has been cold enough to wear that fleece balaclava. Silk glove liners inside my mittens also helped.The title, by the way, is from Rose Sayer (Katherine Hepburn) in “The African Queen”.
Temperatures that cold are fun for other things besides riding. If you throw boiling water into the air it will evaporate before coming to earth. (The actual demonstration starts at about the one minute mark of the video.) If you blow soap bubbles, they freeze. When the break, they shatter like light bulbs. The sensor on my phone had trouble dealing with all that white, but a frozen bubble sits in the middle of the photo.

Six inches of new snow followed the cold, and -30 comes next. (Update: it never got that cold, but close, and by Friday afternoon should be above zero.) Now I know people are getting soft. No newspaper or mail delivery today (Monday). Also, when it gets cold enough, the snow squeaks when you walk on it.
This morning (Wednesday) we added wind to the cold. -26 plus a 20 mph wind (with a brief shot of 30 mph headwind) yielded a wind chill of ~ -50. (F and C are pretty close together at that point.) About a half mile from work, I thought my rear tire was going flat. There was no way I was going to stop. I was willing to sacrifice the tire and tube. A bit later (when I entered the infamous Pharmacy Building wind tunnel – the cause of that brief but monstrous headwind) I realized I was going flat, not the tire. At that point, my lenses fogged and froze and did look like the picture above. The final climb up the hospital driveway was done by memory as much as vision.
I learned that the wind proof membrane in my jacket gets stiff at that temperature. When I moved, it sounded like I was wrapped in cellophane. I feared the membrane had become brittle enough to shatter, like the bubbles I blew. It still seemed to work the next day. The sound of the tire studs biting into the ice was deafening. I wanted to record all those sounds, but didn’t want to uncover my fingers to work the phone. (Besides, the battery went from 100% to 20% charge just sitting in my pocket during the trip.)
The last time I remember a cold snap like was back in my radio days. I read Jack London’s “To Build a Fire” and an except from Ursula K. LeGuin’s “The Left Hand of Darkness” (which takes place on a planet referred to, in English, as “Winter”) on the air that day. I recommend both if you want to curl up with a warm beverage and read on a cold day.
You’ve probably read that this cold is due to the “Polar Vortex”, and you may have read claims that this somehow disproves global warming. Au contraire! A high altitude warm air mass made its way to the pole, causing the vortex, which normally circles the pole, to split and send a lobe southward over central North America. It is currently colder in Madison, WI than in Fairbanks and Point Barrow, Alaska, as well as Lapland (Saariselkä). Parts of Siberia are still colder.
For the climate change deniers, or those who don’t fathom the difference between weather and climate, the National Weather Service reports that, between 1869 and 1999, the temperature in Madison, WI dropped to -20 degrees Fahrenheit an average of 12 times per decade. Since 2000, it has happened twice – in 2000 and this week. The average number of days per decade when the daytime high remains below zero has fallen from 15 in the 1900s to 2 this century. The Winter Biking link above also contains a link to lake freeze data from the University of WI Limnology Lab, which also supports the conclusion that winters are shorter and milder than they were in the 1900s.
We’ll see what the groundhogs think tomorrow.
So when some old codger says that, when he was a kid delivering papers, he often rode his bike in below zero weather and seldom does now, he is telling the truth. If he tells you he walked five miles to school (uphill both ways) and he and his brother took turns carrying each other because they had one pair of boots between them, he may be pulling your leg.
