for parts of the arctic which never become ice- free, the ocean doesn’ t warm at all. what you are missing; however, is that if melting ice caused a positive feedback ( i. more warming than would otherwise be expected) then it would be an automatic tipping point, and there should be no arctic ice whatsoever.
