Earth’s Magnetic North Pole Has Shifted So Much We’ve Had to Update GPS

(6 FEBRUARY 2019)

Scientists on Monday released an emergency update to the World Magnetic Model, which cellphone GPS systems and military navigators use to orient themselves.

It’s a minor change for most of us – noticeable only to people who are attempting to navigate very precisely very close to the Arctic.

But the north magnetic pole’s inexorable drift suggests that something strange – and potentially powerful – is taking place deep within Earth

When north goes south: Is Earth’s magnetic field flipping?

(September 14, 2021)

Something odd is happening to Earth’s magnetic field. Over the last 200 years, it’s been slowly weakening and shifting its magnetic north pole (where a compass points, not to be confused with the geographic north pole) from the Canadian Arctic toward Siba. In recent decades, however, that slow shift south has quickened — reaching speeds upwards of 30 miles per year (48 kilometers per year).

Interplay Between Magnetic Force and Gravity in Massive Star Formation

(September 26, 2021)

The magnetic field is part of one of the four fundamental forces in nature. It plays a vital role in everyday life, from producing electricity in hydroelectric power plants to diagnosing diseases in medicine. Historically, the Earth’s magnetic field served as a compass for travelers before modern technology was available. Crucially for life, the Earth’s magnetic field acts as a shield protecting us from charged particles emanating from the Sun, which are accelerated by the Sun’s magnetic field. Removing this shield would very likely extinguish life on Earth.

Is Earth’s Magnetic Shield Eroding?


The strength of Earth’s main magnetic field is currently about 29.5 microteslas, down 5 microteslas, or 14 percent from its strength three centuries ago.

We know this. There is no question of this.

Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

Ancient Flint Tools Reveal Earth’s Changing Magnetic Field


Today, said Tauxe, the strength of Earth’s magnetic field is dropping very quickly. Although this change isn’t necessarily catastrophic, Tauxe said it could cause problems for some types of technology

Steuerreform: Österreicher müssen Steuer für CO2-Emissionen entrichten

Die Einigung von ÖVP und Grüne auf eine ökosoziale Steuerreform steht. Die Österreicher müssen ab dem 1. Juli 2022 für ihren CO2-Ausstoß eine weitere Steuer entrichten.

Österreich beschließt „Klimabonus“

Wie lässt sich das Steuersystem so reformieren, dass es Klimaschutz fördert? Über diese Frage wird nicht nur in Deutschland diskutiert. Österreichs Regierung hat jetzt konkrete Maßnahmen verabschiedet.

Surge in UK wholesale gas prices fuels winter energy crisis fears


European gas prices rose by 10%, with price pressure exacerbated by a dwindling supply from Russia.

Supply dropped on Tuesday as the flow of Russian gas via the Yamal-Europe pipeline fell by more than half, the Interfax news agency reported, citing data from the grid operator Gascade.

The situation in the UK, where market prices have quadrupled in the past year, is particularly acute.

Gazprom warns of a gas-short winter for Europe


“The gap in terms of injecting gas into European [underground gas storage] UGS facilities cannot be closed. Europe is going to enter the autumn/winter period with a gas shortage in its UGS facilities. The question is, how big is the shortage going to be?” the Russian executive said.

“They might even break new records very soon,” Miller said. He went on to note that despite European prices, Asian markets continued to pay a premium. As a result, gas is flowing into Asia.

Gas supplies to China via Power of Siberia hit 10 bln cubic meters, says Gazprom CEO


„The supplies to China are on the rise, having reached more than 10 bln cubic meters of gas totally since the beginning of deliveries under the 30-year contract (contract on supply via Power of Siberia – TASS),“ he said.

Miller considers the contract with China unique – the largest in the world.

U.S. sanctions spur China and Russia to build up cross-border links


In December 2019, Russia’s state-run Gazprom began operating the Power of Siberia — a natural gas pipeline connecting the Russian Far East and northeastern China. Another pipeline is in the works.

China and Russia plan to increase bilateral trade to $200 billion in 2024.

Steigende Energiekosten: Wie der hohe Gaspreis entsteht

Ist Gazprom und die russische Regierung, die Gaslieferungen nach Deutschland verknappt hat, schuld an der Gaspreis-Explosion? Oder haben sich die Versorger beim Einkauf verzockt? Um diese Fragen zu klären, ist es wichtig zu verstehen, wie der Gasmarkt funktioniert.
