Why the hell is the author mixing Fahrenheit and Celsius degrees?

Paragraph one: " for instance, where humidity routinely tops 90 percent, simply moving around outside when it’s over 105 degrees Fahrenheit would be lethal"

Paragraph two: "At 11 or 12 degrees of warming, more than half the world’s population, as distributed today, would die of direct heat. "

Same paragraph: "At present, most regions reach a wet-bulb maximum of 26 or 27 degrees Celsius; the true red line for habitability is 35 degrees"

Paragraph three: " As I type that sentence, in the California desert in mid-June, it is 121 degrees outside my door. "

Just....why?



I stumbled upon this one too. I suppose the author consulted various sources and forgot to normalize units afterwards.


I'm an american and if you told me it was 27C outside I wouldn't know whether that was hot or cold until I reflected for a moment and compared that number to cpu core temps.

Ignorance on my part, certainly, and not excusable but perhaps typical.


I don't even mind the fact that he used one or the other, it's just that mixing units in a scientific article doesn't seem very....professional for me.

Especially since increase by 12 degrees Celsius != increase by 12 degrees Fahrenheit. So in that paragraph where he talks about 11-12 degrees increase being lethal, you don't have all information necessary.


I never remember the formula, but I know that 0 is freezing and 20 is room temp so I fudge it from there and know that 27 is warm, but not really hot.


Out of interest, why don't you capitalize "American"?

Edit: I'm genuinely curious and not asking to annoy anyone; I might be misunderstanding grammar rules or rules of HN. I ask because I'm not sure this was a mistake; all over the web I see people who write with good grammar, but never capitalize "American". Is it considered rude to capitalize "American"?


HN frowns on meta discussion.

For what it's worth, it should be capitalized but I suspect Americans don't formally discuss themselves in the third person enough to have that grammar rule down.


I don't know about OP, but in some languages(Polish for example) you capitalize proper nouns(so you would capitalize America) but not adjectives(so American or Polish or German would never be capitalized) - so it could be just a cross-language mistake.
