The temperature difference is an interesting problem.
I remember reading about a fatal submerible accident
where the power failed where in cold water somewhere.
Once the temperature in the human occupied space dropped
below a certain temperture the scrubber chemical stopped
working and the crew (or maybe just crew members in the
driver lockout) died.

I can't find any reference to it in the Busby book.
Well, the closest I found was the UZUSHIO incident on
page 690.  The rumour of the design suicide rings a
bell.  Does anybody know more about this?

At what temperatures do scrubber chemicals normally
stop performing adequitely?
