my answer
Black absorbs more EM than white, but black objects also radiate more. All matter above 0 degrees K radiate EM known as "black body radiation". Black objects radiate that energy more quickly than white objects, so they get cold more quickly.
"During the day in a polar region", means that in the dead of winter it's dark out, even at noon. (The question didn't specify the season.) If the sun is below the horizon or very low in the sky (i.e., traveling through a lot of atmosphere), the solar EM wouldn't be much, in which case the black would radiate more energy than the white, and the inside would get colder.
Also, even if there is some sun, the surface of the coat is on the outside of the insulation, so any heat that it absorbs would quickly radiate back out into the air before that heat could penetrate the insulation to help warm you up.
I didn't look any of this up, it all from memory so I can't guarantee it's accuracy.
my answer
I use your by default mostly because I type to fast and dont review what I write. Couple that with the fact that i got into the habit by typing on my phone where an apostrophe is a bit tedious. That particular error, as most of my errors, are largely due to not caring and typing as fast as I can since i dont find the medium to be critical for correctness.
My formal writeups, as well as my blogs, tend to have very few errors since I proof read them.
That said my natural rate of errors has been unusually high the last 2 years since my injury and COVID largely due to the extremely high levels of stress I've been under which seems to effect the prevelance.
When spell-checkers came out, it was a godsend for me. If I left my spelling mistakes in my writing, you wouldn't be able to make out half of what I was saying, it's so bad.
A lot times I can't find the words in the dictionary because I can't spell it close enough to find it. I use Google a lot now because they have AI/phonetics algorhtms.
(I left that last word misspelled, just so you could see how I tried to spell it unassisted so you get a feel what I face with this issue. It's a real pain.)
Actually I know I kid but there is some truth to it. When you are constantly facing fears of death by putting yourself in situations that can be lethal, but ultimately you are in control, you find that most of the day to day things that would otherwise stress you out dont. In a very weird way dangerous hobbies cause the rest of life to be far less stressful.
@Pat Actually the idea that more lethal viruses are less of a thread isnt actually true. For example if a virus kills 100% of victims but takes 30 days to do it it will still spread quite a bit if it is contagious enough.
I debated this some months back and if you look at a comparison between R0 and morality they arent really strongly correlated at all.

Yes, human behavior is a big part of it. With diseases like ebola with all of the bleeding, or small pox with the facial deformities, those diseases probably spread less than they would otherwise because people take them more seriously.
Honestly 90% of the reason people are so reluctant to COVID vaccination or recognizing its severity is because both the democrats and republicans made it a political battle rather than working together and finding a middle ground that was denialism or forcing people at gunpoint to obey.
Long before we even had a vaccine I mentioned that vaccines would fail no matter how many people were on board, and surprise surprise, it played out almost exactly the way I claimed.
There is a reason we have never had a successful vaccine to any coronavirus class virus in existance. Every vaccine we tried never made it to market due to the exact sorts of problems we are seeing
@freemo Have you considered the need for boosters in your equation, though? Long covid and risk of needing hospitalization so far seems to have decreased hugely with the vaccine.
The current ones needing hospitalization despite being vaccinated are the ones who got vaccinated the first in the timeline, and also very usually are either elderly or have more ailments than just this virus. They're highly due for boosters now.
That's the same situation in Israel. I remember us chatting about this, and the Israelians (is this a word? Well, it is now.) were among the first to get vaccinated. Not too surprising that about 6 months later there was another surge.
Vaccinations aren't 100% effective, but we already agreed on that. Boosters would be a likely necessity, but we already knew of that. That's why the current talk is now 'BOOSTERS!'. We'll see how that pan out, I think they might help.
When i explained my concerns in the past I did go into detail on boosters. What I had said at the time is that for a vaccine to have any potential of working it would need boosters that would likely need to be very frequent, on the order of every 3 months to 6 months, which is not practical as a long term solution and overtime presents ever increasing risk since the nature of mutation of corona class viruses are not like flu viruses. A flu virus undergoes recombination and thus its next gen viruses are not any more deadly or specialized, they just make the vaccine less effective. Corona class viruses as they mutate to stay ahead of vaccines undergo a more classical form of mutation and as such create an ever increasing risk as you vaccinate against it, presuming you even find a booster every 6 months to be palatable at all.
@freemo Yeah, as this is still largely untested fields for this virus you certainly do have a point. Though there are more factors at play, of course.
I see boosters as a way to buy time at the moment until we have a more permanent solution. Even without boosters the virus would mutate anyway.
Also, boosters can still go two ways at this point. Either you would need regular boosters, or the third (or maybe fourth) booster would be the end solution. Some vaccinations for other ailments needed a 3rd booster much later as well. But seeing as we haven't got much long-term experience yet with this virus it is still largely guess-work at this time.
@freemo Oh, really? Even smarter than you? I'm so honored. ;) And since you're always right, it must be true!
