The issue is already confused. People like you who want to pretend it's not
only serve to confuse it even more.

Forget "all the stuff others have posted about temperature" at your own
peril. It's every bit as important an altimeter error as that caused by
changes in pressure.



While temperature may play a role in altimeter "errors" I believe
it's extraneous to the discussion at hand. The phrase in question says
nothing about why the pressure is changing, only that it does. The
effect of this pressure change on altimeter readings can - and has
been - adequately explained without discussion of temperature.

We can always discuss temperature effects once the pressure effects
are understood. Trying to get someone to grasp two separate concepts at
the same time when it's not necessary does only serve to confuse the
student.
