The coldest location on the planet has experienced an episode of warm weather this week unlike any ever observed, with temperatures over the eastern Antarctic ice sheet soaring 50 to 90 degrees above normal. The warmth has smashed records and shocked scientists.
“This event is completely unprecedented and upended our expectations about the Antarctic climate system,” said Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France…
“Antarctic climatology has been rewritten,” tweeted Stefano Di Battista, a researcher who has published studies on Antarctic temperatures. He added that such temperature anomalies would have been considered “impossible” and “unthinkable” before they actually occurred.
Parts of eastern Antarctica have seen temperatures hover 70 degrees (40 Celsius) above normal for three days and counting, Wille said. He likened the event to the June heat wave in the Pacific Northwest, which scientists concluded would have been “virtually impossible” without human-caused climate change…
The historically high temperatures in Antarctica follow a pulse of exceptional warmth on the planet’s opposite end. On Wednesday, temperatures near the North Pole catapulted 50 degrees above normal, close to the melting point.
Put it on rewind and play it again and again. Sooner or later, folks in the GOUSA will begin to comprehend this is a legitimate emergency. A positive response is needed.

I think it was the American comedian Chris Rock who predicted that people wouldn’t care about global warming until after their babies started self-combusting.
Normal
noun: normal; plural noun: normals
1. The usual, average, or typical state or condition. “her temperature was above normal”
Seems at best archaic to continue to refer to things that for all intents and purposes no longer exist as being ‘the usual, average or typical state or condition’.

“…Ice shelves, permanent floating sheets of ice attached to land, take thousands of years to form and act like levees holding back snow and ice that would otherwise flow into the ocean, causing seas to rise.
The March heatwave, with temperatures reaching 40C (70F) above normal in parts of East Antarctica, was tied to the atmospheric river phenomenon, said Peter Neff, a glaciologist at the University of Minnesota.
This process creates columns hundreds of kilometers long that carry water vapor from the tropics, creating an effect Neff described as “a fire hose of moisture”.”
