Temperature is not scalar
Messers Rankine, Kelvin and even Fahrenheit would beg to differ… Temperature is scalar, however it’s effects on living things is generally not mostly owing to chemistry.
The claim that a 40° C jump in Sub-Zero temperatures is tolerable, but wouldn’t be in the UK or whatever they’re saying in this article… That’s nonsense
Au contraire my dear fellow. For a human, the article is entirely correct. A rise of 40° C in a particularly cold place is indeed tolerable for a human. A similar rise in, say, the UK today would put the temperature at 52° C - hotter than Death Valley on a well above average day and considerably less tolerable.
Of course a single recorded rise in temperature isn’t a good indication of climate…
One thing other answers have missed is that some ssds encrypt data before writing and obviously after reading (this prevents a swap the storage controller type attack) A secure erase on such a device consists of changing the read/write key. Takes milliseconds. Irrevocable (unless you find a way to read previous contents of the key storage)
