This summer, the polar ice did not drop as far as it had last year. Climate change, resulting in higher volume transfer of water to the north, it freezes rapidly at winter onset, covering the northern latitudes with reflective white. Sun absorption drops and we get a stable ice over condition, if the ice starts to hold all summer, a new ice age!
Real? A low but not insignificant probability. The antarctic continent holds ice all year;it is reflective even with thin ice. So a net transfer of ice to the North does the trick. The antarctic, where the research vessels are stuck, is way over on its amount of ice compared to recent years. Its variation is smaller, because of the continent, but ice growth indicates as increased transfer of water from equator south during their winter. So, a sudden movement of excess water from the equatorials to the north, where sea ice has greater seasonality, makes a risk of an ice over.
