    CNN is warning that the Arctic is warming

    Yes summer is coming again to the Northern Hemisphere.

    (CNN)As sea ice vanishes, and the planet's northernmost forests, new research confirms what scientists are sounding alarms about: the Arctic has warmed much faster than the rest of the world in the past several decades.

    The phenomenon, called Arctic amplification, is caused by the heat-trapping emissions from burning fossil fuels. The pace of the temperature increase around the North Pole in recent decades was four times higher than the rest of the planet, researchers at the Finnish Meteorological Institute found in a study published Thursday.

    Another problem: Climate models, which scientists used to predict long-term change, are not capturing this high rate of warming, lead author and researcher Mika Rantanen told CNN, which was part of this study's motivation. That's concerning because if the models can't recreate what's happening right now, scientists can't be confident in their long-term predictions.
    "Because of this discrepancy, we decided that this needs to be corrected," Rantenen said. "This needs to be updated."
    The , published in the journal Communications Earth and Environment, analyzed temperature trends in the Arctic Circle between 1979 and 2021 — the modern era of satellite data. They found the rate of warming is particularly high in the Eurasian region of the Arctic, especially the Barents Sea, which has warmed seven times faster than the global average.
    Recent that the annual average temperature in the Barents region climbed by as much as 2.7 degrees Celsius (4.9 degrees Fahrenheit) each decade in the past 20 to 40 years, making the Barents Sea and its islands the fastest warming location on the planet.
    Climate change has triggered a rapid loss in sea ice in the Arctic region, which in turn has amplified global warming. Bright white sea ice reflects solar energy back to space, but when it melts, the dark ocean absorbs that heat.
