When Peter visits Doctor Strange at his Sanctum Santorum, he finds the interior of the building covered with snow. As it turns out, one of Doctor Strange's portals was connected to Siberia, and a blizzard came through. Both Strange and Wong (who is now the Sorcerer Supreme) are seen wearing jackets to keep warm. Strange also has on a Columbia University sweatshirt, which is a reference to his alma mater in the comics.
