arctic circle Warmed at four times faster than the rest of the planet in the past 40 years Because of climate change, according to a report published this Thursday that warned the phenomenon was deeper than the latest studies indicated.
This was determined by a team of experts from Norway and Finland, who analyzed temperature data collected via satellite in the Arctic region since 1979, making An average warming of 0.75ºC was recorded every decadeFour times more than the rest of the planet, explained the scientists in the study published on the scientific portal Communications Earth and Environment. “Until now it was believed that the Arctic was warming about twice as fast as the rest of the planet, so I was a little surprised when our figure turned out to be much higher,” he explained to the agency. AFP Antti Lipponen, study co-author and member of the Finnish Meteorological Institute.
In its final report for 2019, the United Nations Organization (UN) group of climate experts had calculated that the upper percentage of warming is known as? “Arctic Amplification”, It was two to three times larger than the rest of the planet. The researchers also recorded “significant regional variations” within the Arctic Circle and within regions such as the Eurasian Arctic Ocean near Svalbard (Norway) and the Novaya Zembla (Russia) archipelago that warmed up to 1.25º C per decade, i.e. seven worlds many times more than the rest of the
“Climate change is caused by humans. As the Arctic warms, its glaciers will melt and that will affect sea levels globally,” Liponen said, “Something is happening in the Arctic and it will affect us all. ” ,
The warming of the Arctic region, he assured, have a profound impact on local communities and in wildlife, such as polar bears. With this accelerated warming caused by climate change, the ice in the Arctic region is absorbing heat instead of bouncing back as it should, and that excess water from the continental and insular regions of the polar circle is largely oceanic. is directed towards.
The thaw in Greenland is thus approaching a “point of no return”, and that frozen mass contains enough water to raise sea levels “by six meters across the planet,” AFP reports.
According to the Intergovernmental Panel on Climate Change, 1900. The sea level has risen by 20 centimeters since And this phenomenon has been accelerating since the 1990s, in a context in which climate change has increased the planet’s average temperature by 1.1ºC compared to the pre-industrial era.
According to the World Meteorological Organization, the increase in temperature is likely to be between 2.5 to 3 degrees, as published tel.
