You're missing my point completely. If a news article is targeted at a US resident, it should use Fahrenheit for maximum impact. Globally and scientifically, of course use Celsius -- or even better, mention both.

This article isn't targeted at a US residents, but your comment seems to imply it should use Fahrenheit.

My comment was a generalization of climate change articles in general, figure it out and stop being pedantic.

F does have that nice comfort-zone granularity though. Swingier whole numbers around the zone of human activity. Maybe there's a way in which the numbers could be displayed side by side... Even for sheer generic number effects

I think that's mostly because you're used to it. I know that 18-22 °C is comfortable because that's how it is, but that's just out of habit.

A 1°C difference is about 2°F. Not that much more granularity and in practice we just round to the nearest °C and it gives a pretty good idea. It’s like inches and pounds: purely a matter of habit. OTOH, using °C makes much more sense for other reasons.
