Arctic and Antarctic sea ice

The polar day/night cycle acts much like the daily cycle insofar as the warmest and coldest parts are not polar noon and midnight (solstices) but roughly before the Equinoxes much like the 'rule of twelfths' of tides -

The area where the Sun is constantly in view with the North pole at its center is beginning to diminish with greater pace while we experience at our latitude as a greater rate of declination and daylight length differences.


Splitting the planet's two day/night cycles apart is such a productive and creative thing to do as part of nature like the cicadian rhythm responds to the 24 hour cycle, other parts of nature responds only to the annual cycle while other parts of nature respond to both in combination (seasons).

How apt for the crate-mounted ranter of medieval, nonsense verse.

Here's a modern, first edition for you:

Strumpy has/had a GREAT flock of lambs,
Being GREAT lawyers was their job,
To protect the 1% from the working poor,
So that US billionaires will never hang. ;-)
