Neither is correct.
440m underground is deep enough that you're well under the cold temperatures immediately underground, but not so deep it's painfully hot. It's probably a super stable temperature year round, and you could probably spend all day every day at 440m and the worst you'd have is it's pretty stuffy being surrounded by rock. Ventilation is key in something like that, because it'd be humid and without getting fresh air it gets stale and eventually could get quite dangerous as well.

@sj_zero@social.fbxl.net @deprecated_ii@poa.st the problem, and what makes the whole guy's argument more retarded, is that they are not 440m underground as in "below the sea level". They have a tall mountain over them, which makes them 440m under the surface of said mountain. They didn't dig 440m down and then created their underground city near the magma layer or something like that.
