The solstice occurred at 6:11 am this morning. For the majority of humanity who dwell in the northern hemisphere, winter has begun, which paradoxically means the days get longer. The lag between declining amounts of sunshine and annual northern hemisphere cooling, and increasing sunshine and global warming, gives us temperate gloom in November, and sunny cold in February.
Thus, by extension, does the planet continue to heat for a while, like a warm day in October, as the long slide into the next ice age continues apace from the sunshine maximum of 9,000 years ago. Cosmic inconveniences like Milankovitch cycles need to be considered.
A merry Christmas to you all.
