Source=Arctic Sky Illuminated by Mesmerizing Nacreous Clouds

NASA’s MERRA-2 climate model reveals that the Arctic stratosphere has reached a 40-year record low for December, creating a sudden appearance of polar stratospheric clouds (PSCs) far beyond their usual Arctic confines.
Recent observations have revealed a remarkable surge in polar stratospheric clouds (PSCs), often referred to as the most beautiful clouds on Earth due to their aurora-like colors.
This sudden increase is attributed to a 40-year record low in temperatures within the Arctic stratosphere for the month of December, as indicated by NASA’s MERRA-2 climate model.
PSCs form under extremely cold conditions, typically around -85 °C (-121 °F), in the otherwise cloudless stratosphere. The unusual cold snap has caused these clouds, usually confined to the Arctic, to descend all the way to mid-latitudes.
Notable sightings have been reported over Locarno, Switzerland, Torun, Italy, and Lausanne, Switzerland, locations well beyond the normal range of PSCs.
This phenomenon represents a significant deviation from the typical January start of the PSC season. The current extreme cold wave has not only given rise to an early onset of these clouds but also suggests the potential for increased occurrences in the coming weeks.
On December 24, 2023, the Arctic stratosphere is warming but it’s still cold enough for polar stratospheric clouds.
The earth has a fever!
And the cure is more cowbell.
Honestly, it just won’t matter.....

Impossible! Polar bears are being parboiled??
“PSCs form under extremely cold conditions, typically around -85 °C (-121 °F)”
For those not versed in English too well, the above temperature is F-ing COLD.
Those low temperatures should cause carbon dioxide to sublimate from the atmosphere. The sublimation temperature at normal atmospheric pressure is -78.5°C (-109.3°F). There should be carbon dioxide “snow”.
In USAF Weather school they called them Nacreous clouds.
Record cold temperatures caused by global warming. Sure, that makes sense...
...to leftists and low IQ types.
Oops, I just repeated myself.
The increased amount of warm air over the middle latitudes are pushing all of the cold air to the poles? Yeah - that’s the ticket!
China got a major blizzard last week

Very pretty
The Arctic is giving global warming activists the evil eye!
Record low temperature, but still "warming". How does that work?
But because of global warming, it’s an unusually high 40-year low.
“In USAF Weather school they called them Nacreous clouds.”
So you must have been in USAF weather. Same here.
How will this affect a reindeer drawn sleigh?
Beautiful.

It’s Trump’s fault.
