Uboats operated in the arctic circle so that part is false, here is them hunting polar bears. This was also from one of the less adv Type VIIC Uboats
They spent a lot of their time hunting the allies in those icy conditions just fine so its not really a problem.
Artic Uboat
Submarines have more problems with being way too hot due to the engines, motors and battery's, they had to develop air conditioning systems in Uboats to keep them cool as they were always too hot.
The later more advanced Uboats were also better insulated due to the sound absorbing material as well.
The Type XB Type XXI had freon air conditioning that could cool and heat the UBoat to solve this issue, so they could operate in hotter and colder conditions.
So yes they could easily operate in cold conditions and did.
Also there are many caverns that have recorded temp of over 20C 68F, Lots of geothermal in Antarctica. They have been discovering them all over Antartica Warm caverns
Good information. Thanks for the brief. But the type XXI never became operational, so its characteristics are moot. They may also have been taking advantage of the North Atlantic Drift and the Norwegian Current, bringing warmer water northward.
I don't think these ice caves are open to sea level, from the article's description.
It still remains a fancy that they could have established a base. Undiscovered for 80 years? To do what?

Your theories do not hold water :)
