Link 1: The only noticable effect discussed re: high altitude is the more rapid expansion of the CO2 gas, physically altering the bread dough, as it rises. This hardly seems relevant to wine-strength during wine-making. The practical problems discussed and advice does indicate that altitude matters for cooking, but not for wine-making in any big way.
I think altitude is a red-herring here.
Link 2: mentions this:
"even how other more subtle changes like altitude, ambient temperature, or natural yeasts in the air affect what you do." But of course this talks about altitude and temperature as an effect on cooking, not on yeast or yeast growth/alcohol production. I am sure their advice is valid, but again, it doesn't clearly support your thesis about alcohol strength being significantly altered from the norm.
Link 3: "
If the yeast is given moisture and a small amount of sugar to help it get started, it will react much more favorably to the environment and, bolstered by the energy received from the sugar, it will use the moisture to travel more quickly and ferment more of the flour. In a warm environment, the process is even more enhanced, as the metabolism of the yeast is increased and the organisms feel even more comfortable moving and eating. Cold temperatures have the reverse affect.[sic: = effect]"
Here there does seem to be a case for higher temperature speeding up the metabolism of the yeast and producing alcohol faster. This would not at all change the maximum % alcohol when the yeast died. Also, the text implies that Yeast are capable of directed mobility, whereas your own .pdf denies this absolutely! Sounds like these people need a biology lesson.
Link 4: This last educational video clearly stresses atmospheric pressure as the main problem for baking (and this makes obvious sense for items which use the CO2 production to "rise" cakes, doughs, and soffle's). But again, I can see nothing here that would indicate that Atm. pressure would dramatically affect the alcohol content in wine allowed to naturally ferment, whether it was on a mountain, at sea-level, in Iceland or in the Sahara. The only thing affected is the rate of fermentation, i.e. ,the speed of alcohol production, not the potency of the product.
As far as one of the most righteous men and it not being hard because there were only eight, there weren't only eight before the flood!
Since the population BEFORE the flood was so wicked God felt it necessary to utterly destroy them all, the 'high score' for Noah's morality seems a bit tainted and artificial. It could be paraphrased as:
"Noah was a lot better than the murderers and monsters God had already decided to destroy."
More of a consolation-prize than an honor/award
