As the Earth has this wobbling cycle around a 26,000 or so year cycle when the Arctic tilts more towards the sun getting more solar exposure the Antarctic gets less solar exposure.
Currently we’re about half way in the Arctic tilt from a more solar exposure towards less solar exposure thus the North Arctic is cooling. At the same time the South Pole or the Antarctic is warming. In around another 6,500 years the opposite tilt will start to occur. Back and forth this happened every 13,000 or so years, as the Earth tilts from side to side, thus warming either the North Pole or the South pole in that 26,000 year tilt of the axis of the Earth, each pole getting more or less solar exposure, or heat. We’re about halfway now in the north heading towards less solar exposure or cooler, but the South Pole is getting warmer, thus a balance over-all maybe.
