‘Unthinkable’: Scientists Shocked as Polar Temperatures Soar 50 to 90 Degrees Above Normal

“With everything going on in the world right now, the dual polar climate disasters of 2022 should be the top story”

BRETT WILKINSMarch 20, 2022

Scientists expressed shock and alarm this weekend amid extreme high temperatures near both of the Earth’s poles—the latest signs of the accelerating planetary climate emergency.

“This event is completely unprecedented and upended our expectations about the Antarctic climate system.”

Temperatures in parts of Antarctica were 50°F-90°F above normal in recent days, while earlier this week the mercury soared to over 50°F higher than average—close to the freezing mark—in areas of the Arctic.

Stefano Di Battista, an Antarctic climatologist, tweeted that such record-shattering heat near the South Pole was “unthinkable” and “impossible.”

“Antarctic climatology has been rewritten,” di Battista wrote.

The joint French-Italian Concordia research station in eastern Antarctica recorded an all-time high of 10°F on Friday. In contrast, high temperatures at the station this time in March average below -50°F.

Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France, told The Washington Post that “this event is completely unprecedented and upended our expectations about the Antarctic climate system.”

“This is when temperatures should be rapidly falling since the summer solstice in December,” Wille tweeted. “This is a Pacific Northwest 2021 heatwave kind of event,” he added, referring to the record-breaking event in which parts of Canada topped 120°F for the first time in recorded history. “Never supposed to happen.”

Walt Meier, a senior research scientist at the National Snow and Ice Data Center in Boulder, Colorado, told USA Today that “you don’t see the North and the South [poles] both melting at the same time” because “they are opposite seasons.”

“It’s definitely an unusual occurrence,” he added.

As Common Dreams has reported, the Arctic has been warming three times faster than the world as a whole, accelerating polar ice melt, ocean warming, and other manifestations of the climate emergency.

“Looking back over the last few decades, we can clearly see a trend in warming, particularly in the ‘cold season’ in the Arctic,” Ruth Mottram, a climate scientist with the Danish Meteorological Institute, told the Post. “It’s not surprising that warm air is busting through into the Arctic this year. In general, we expect to see more and more of these events in the future.”

Why are there calls to ban Bitcoin mining?

Why are there calls to ban Bitcoin mining?

Bitcoin, Ethereum and other PoW cryptocurrencies create significant carbon emissions with each transaction. According to the Digiconomist Bitcoin Energy Consumption Index, a single transaction creates 1259 kilograms of carbon dioxide emissions, which is the same carbon footprint of a trans-Atlantic flight from London to New York and back again.  

To look at it another way, a single financial transaction using Visa consumes 1.5Wh of electricity on average. Digiconomist says that the average energy use per Bitcoin transaction is 2258 kWh, which is enough to power a single US household for two and a half months.  

Alex de Vries, founder of Digiconomist, told Tech Monitor that the Bitcoin network alone generates 200-quintrillion “guesses” a day as part of a numbers game to create one block.  

“You have all these machines in the network effectively playing a massive game of guessing numbers and the only one who guesses correctly gets to rate the next block,” he explains. “That’s a huge amount of energy you need to do that to create those new blocks.”

He explains that per year there are 100 million Bitcoin transactions, which is relatively low. However, the carbon footprint to generate new blocks is over 100 megatons of carbon dioxide. “That’s twice the size of Greece’s [carbon footprint],” he says.  

The Bitcoin network also uses specialised hardware that creates 386 grams of electronic waste (on average) per transaction on the Bitcoin blockchain. “This is the equivalent to the equipment weight of two iPhones,” explains De Vries.
