Antarctica
It is getting colder. Not as cold as it gets but colder. There are less temperate areas.
Vostok is - 52 degrees Centigrade with humidity of 32% with an elevation of 3420 meters, while Base Jubany, Antarctica at elevation of 4 meters is 5 degrees Centigrade with 79% humidity.
The trend currently is toward freezing and consistently so. The temperatures along the coast at lower elevations are cooler, primarily due to the migration of the sun. The sun has reached a point on the curve of Earth that is affording Antarctica some relief from the heat.
The ‘change’ to a colder climate over Antarctica today is also evidenced by the increase in ‘wind’ velocity (click on), especially over East Antarctica. That tells me there is significant change in air mass temperatures. Rising, falling air masses. Colder falls, heat rises. Not at all homogenous today as it was the other week, which to me was very spooky and ominous. The only air movement then was the jet stream. Today the jet (click on) is being impacted by the winds and that is a good thing. No ‘latent’ heat lying around to continue to sublime ice.
