Studies show the Arctic is warming up to four times faster than the rest of the planet

The Arctic is warming faster than anywhere else

Scientists have known for years that the Arctic is suffering more from warming than other parts of the world. But new research shows it's far worse than previously thought. Arctic amplification -- but was published Thursday in Nature Communications Earth & Environment A new study found that it's actually twice that. The Arctic is warming almost four times faster than anywhere else on Earth. Some regions of the Arctic Ocean are warming up to seven times faster.

lead author Mika Rantanen describes trends from 1979 to 2021 when 

As a result of introducing these guidelines, the North Pole is more likely to be her We found that it is warming 3.7 to 4.1 times faster. 

The factors causing more intense warming in this region have long been known. Sea ice, which helps reflect the sun's rays, is shrinking, allowing the open ocean to absorb more radiation. The absorbed radiation melts more ice and traps more heat, creating a devastating loop. 

Scientists believe that changes in air pollution levels in Europe may also play a role.

We report that the Arctic has warmed four times faster than Earth's in the last 43 years. The

4-fold Arctic amplification factor (AA) is higher than commonly reported in the literature and media.

The amplified warming rate is greatest in the ocean and tends to be higher in autumn and winter when sea ice is expected to expand and release heat into the atmosphere. But earlier this year, NASA found that Arctic sea ice growth last fall and winter was, the 10th lowest insatellite records.

And regionally, Rantanen tweeted that "warming is getting stronger." 

"The Barents Sea region near Novaya Zemlya warmed up to seven times his global average," he writes. 

Another study, published in June this year, found that the Barents Sea has experienced an “exceptional” temperature rise of nearly degrees Fahrenheit perdecade over the past 20 to 40 years. warming” was observed. With findings consistent with sea ice loss 

, why have previous studies underestimated Arctic warming? . Rantanen and his team believe that many other studies use "older, possibly outdated" estimates rather than recent observations. 

North Pole Specific regions of the polar region were also differentiated between studies, the latitudes used ranged from 60°N to 70°N, and in other studies the North Pole was not even defined based on latitude. 

Additionally, researchers discovered problems with predictive models. Rantanen said climate models as a whole underestimate the true Arctic amplification.

"The magnitude of Arctic amplification depends to some extent on how the Arctic is defined, but climate models underestimate Arctic amplification for the periods used in the calculations. It turns out to evaluate the definition,” Rantanen said in a press release. 

First published as a preprint in July 2021, the discovery of lantanen waspresented to NASA climate scientist Peter Reflecting Jacobs' reportAt this time, the North Pole is defined by the tilt of the Earth, as Jacobs explained at 

"We all know [the Arctic] is the canary when it comes to climate change," he told the journal Science. This is just a banana. 

As stated in the abstract of Jacobs' presentation, changes in the Arctic will have "profound impacts" on climate, humans, and ecosystems.

"It is imperative that the scientific community not only accurately understands the magnitude of Arctic warming, but also communicates it," the abstract reads.
