Actually, what is coming across is the fact that you want Magneto to be able to beat Storm. You have seen that his only hope would be to try an iron-in-the-blood trick. I have shown in canon where Storm has powers that nullify the effectiveness of this against her. You are fighting tooth and nail out of desperation. That said, I am going to explain why that scan showed the cold affecting Storm that way eventhough it was stated that she is immune.
Storm cannot be directly harmed by the elements or any of its manifestations as stated here in Uncanny 168:

The reason the elements affected her like that in those panels is because she had just returned to Earth from a stay of MONTHS in space. When Storm goes to a new planet, etc, there is a period of adjustment she has to go through to get attuned to the planet's life-force and ecosystem. Her ability to perceive life, manipulate the elements and her immunity to the elements is dependent on this unity she has. We saw this in the "STorm" mini that came out in the 90s when she was transported to "The Hill" dimension. She saw this in the original "Secret Wars" with the Beyonder. This was also shown in other story arcs.
Storm's unity with life itself gives her the ability to even communicate with plants.

However, after her long stay out in space, she had to get readjusted to Earth and her unity with life on this planet was off kilter for a bit. See the scan here:

However, by Uncanny 185, this is obviously restored to a degree as seen in that scan where Storm allowed Rogue to borrow her powers for a bit here:

After this all though, she was able to bond with planets and all MUCH faster than than this. Heck, even before then, in the Galactic Core, she was able to bond with the core immediately and summon its full power.

Notice here that she alters the weather over the entire North American continent (which is MUCH larger than Antarctica). However, she first flies to the point where the air was so thin and cold that a normal human would perish in seconds. She then channels the blizzard *through* her body to the top of the atmosphere and has no problems whatsoever with this stuff. Her body did not change temperature here to compensate because her body is immune to temperature variation and climate. This fact was stated in a story where Storm went swimming at the mansion nude. Nightcrawler came in and was caught by surprise. Unfortunately, I do not recall the issue where this was stated. However, the scan I provided from Uncanny 168 states that she cannot be directly harmed by the elements (which is even better as it includes this). However, in Storm: The Arena, we see it brought up once again that Storm is immune to the elements (Note: this story comes after the Lobdell/Kelly/Seagle era which limited Storm to a mere resistance!):

She has also held within her body the full electrical power of a storm. Let me throw some facts at ya. Lava gets no hotter than 4000 degrees F. The surface of the sun is 11,000 degrees F. The average lightning bolt is about 55,000-60,000 degrees F. A positively charged lightning bolt is hundreds of times more powerful than a regular one. A hurricane carries enough power at any given moment to power the US for 6 months. Storm can hold in her body the full electrical power of a storm. Imagine the temperatures of all of that power/energy concentrated in the space of a human body! She had no problems with that either.
As a matter of fact, in these scans, she replinishes her lifeforce with elemental phenomena (in this caseby summoning down lightning upon herself) which also overwhelms the antagonist sucking the life force from her body:

Imagine the temperatures in her body and the extreme radiation content and EM energies when she flew into the galactic core and absorbed the energies of millions of stars which was all condenced in her body to form one star that was the sum of the core here:

This stunt left out in deep space unprotected as it destroyed her space-ship. She can only survive a few minutes out in space unaided as it was established between Uncanny 160 and 165 (one of those issues). This stunt came from Uncanny 165. In Uncanny 166, we see her floating aimlessly in deep space in the last moments of her life when the Acanti find her and heal her. Here is the scan in Uncanny 166 that gives a flashback to what happened after this scene in 165:

One more, no problem with the temperatures of MILLIONS of stars!
Now other stories to refute Storm being able to alter the ecosystem over limited areas include as she controls it over VAST areas include:
2) In BP issue 15, the weather over the entire African continent is altered by Storm. (Africa is MUCH larger than even North America!)
3) In "House of M," Storm permanently alters the weather across Africa to make it furtile and improve the economy drastically. The Handbook during this time states that she can alter weather over vast areas!
4) X-Men: The Hidden Years issue 7 where she stops a continent-sized hurricane cold.
5) In the 1991 80 page Winter Special from Marvel, Storm blocks solar flares from the sun that would have wiped out the entire planet by altering the entire planets ecosystem while also tapping into a machine that only shoots gamma rays and pulling out enough gamma rays to envelop the planetwhile at the same time using the energies from the Earth on a global level together to form a gamma-shield to block the sun blasts here:
