Sea ice evolution

On average,a square kilometer of sea disappears every second this time of year as the Earth reaches this particular position along its orbital circumference and the prolonged exposure of the Northern polar latitudes to solar radiation over the last 5 months takes full effect. Much like the daily cycle at lower latitudes where the warmest part of the day is long past noon, the orbital day/night cycle, at least in the Northern hemisphere, the warmest period is July/August/Sept.

Isolating the Earth's surface rotation to the central Sun via sea ice evolution is an excellent way to remove the older and less effective tilting Earth or those who chatter about sea ice and its long term status while ignoring the dynamic behind its annual occurrence.

A response in sea ice extent to variations in inclination allows for speculative approaches as climate is defined within a spectrum from 0 degrees to 90 degrees hence the awkward 'tilting' Earth interferes with the productive approach which compares all planets and their climates within te solar system using inclination as a benchmark.
