"The North Pole continues to shift which creates a shift in the core ice shelf and adjusts temperatures in places based on the proximity to that shift accordingly.

As the Northern ice shelf shifts the Southern one adjusts of course also. All very cool and interesting seeing how our beautiful planet works." - John Lemp

Which changes the ice caps at both ends and global climate as a whole. And humankind has nothing to do with it. Just natural forces of a living, constantly changing, planet and star system. Ain't the sumpthin'? 😉
