Extreme Warming at the Poles this Week — Arctic and Antarctic Temperatures to Rise to 20-30 C Above Average in Some Locations
Human-caused climate change via fossil fuel burning produces a number of stranger things. And some of the weirdest happen to occur in the polar regions of our world.
One of the foremost of these odd impacts is called polar amplification. Under polar amplification, the warming effects of elevated greenhouse gasses are concentrated at the poles. This is due to reduced reflectivity (albedo) from smaller snow and sea ice concentrations, due to the increased intensity of the greenhouse effect in colder and darker regions, and due to increased energy transfer from lower latitudes into upper latitudes due to weakening of the polar Jet Stream.
Over the next week, this kind of polar amplification is predicted to generate very extreme warm temperatures for both poles of our world.
In the Arctic, temperatures in both Northern Greenland and on the Siberian side of the Arctic Ocean are predicted to hit ranges higher than 20 degrees Celsius above average (36 degrees Fahrenheit) with some readings over Northeastern Siberia striking near the 30 C above average mark by early next week (54 degrees F). This will produce near or above freezing temperatures over both Siberia and sections of the Arctic Ocean near or north of the 80 degree North Latitude line. Overall, temperatures are predicted to average as high as 4.4 C above average for the entire Arctic. A very considerable warm temperature departure consistent with the heightened levels of global warming the world has been experiencing during recent years.
Primary atmospheric drivers for these warming events are large synoptic warm wind patternsdrawing above average temperatures into both the Arctic and Antarctic. In the Arctic, winds crossing hundreds of miles of warm Pacific Ocean in association with the back side of a high pressure system moving over the Bering Sea will draw these very warm temperatures northward. In the Antarctic, warm winds funneling southward from Australia will reinforce the influence of a strong high pressure dome over East Antarctica even as another strong synoptic warm wind pattern feeds into West Antarctica off the Pacific and Southern Oceans later in the week.
It’s very early for temperatures over parts of Antarctica to be pushing above freezing. And it’s rather late for such similar temperatures to be continuing to invade so far north into the Arctic. So much warmth will have an ongoing deleterious impact to both sea and land ice as well as snow cover. Contributing to the overall pattern of warming and melt we’ve seen for both Antarctica and the Arctic during recent years as global temperatures have risen into a range from 1 C to 1.2 C above 1880s averages.
Ik kwam zojuist mijn oude vriend, de bestseller-auteur en mainstream-opiniemaker Geert Mak in de regen op straat tegen. Na elkaar te hebben begroet, vertelde Geert mij dat hij van oordeel is dat Europa zo snel mogelijk met Rusland om de tafel moet gaan zitten, om de opgelopen spanningen te deëscaleren. De VS heeft heel andere belangen dan 'wij,' aldus Mak, die benadrukte dat de macht van 'onze' Atlantische bondgenoot ingrijpend aan het afnemen is. Kortom, ik hoorde wat ikzelf al enige jaren op mijn weblog schrijf. Opvallend hoe een Nederlandse opiniemaker binnen zo'n betrekkelijk korte tijd zo wezenlijk van oordeel kan veranderen. Immers, Mak’s gevaarlijke anti-Rusland hetze was een treffend voorbeeld van zijn opportunisme. Mei 2014 beweerde op de Hilversumse televisie de zogeheten ‘chroniqueur van Amsterdam, Nederland, Europa en de VS,’ dat er sprake was van een 'Russische gevaar,’ aangezien ‘meneer Poetin’ aan ‘landjepik’ deed en dat de Russische president d…

WHITE EARTH RESERVATION, Minn.—Candice (not her real name) awoke with a start. Someone was pulling down her sweatpants. It was a male friend.
“Stop!” she shouted.
He kept groping her. She kicked him and he fell off the bed. She dashed out of the bedroom, tripping and tumbling down the stairs. Gripped with fear, she heard his footsteps behind her in the dark and forced herself to stand upright as she staggered out to the porch.
Candice was still intoxicated. She got into her car and drove into a ditch. A white police officer pulled up. She struggled to hold back tears as she told him about the attempted rape.
All the officer saw was a drunk and disorderly Native American woman. He dismissed Candice’s report of sexual assault as a lie she had made up to avoid getting a DUI. He did not take her to the hospital for a forensic exam. The sexual assault was not recorded in his pol…
