The Arctic is warming faster than the rest of our Earth. This is now a fact well known to scientists. But they are telling us today that this accelerated warming will have serious consequences for the entire planet.

The Arctic is warming faster than our Earth’s average. Almost four times faster! This is far from good news for the region.
The Arctic is warming much faster than expected, study reveals!
And this is not good news for the rest of the planet either, researchers from theUniversity College London (UCL, United Kingdom). A study that they publish in the journal Earth System Dynamics shows how the rapid warming of the Arctic – which scientists sometimes call “Arctic amplification” – adds uncertainty to climate forecasts and above all, impacts global warming.
Arctic warming and its consequences around the world
Because sea ice, for example, helps keep our Earth cool by radiating heat back into space instead of letting water absorb it. So its withdrawal under the effect of accelerated global warming in the Arctic tends to cause global temperatures to rise a little further. Thus, researchers’ models show that Arctic amplification will result in the 1.5°C threshold being exceeded five years earlier than without it. And even exceeding the 2°C threshold some eight years earlier.
An impact on the global goals
“Climate change in the Arctic is often overlooked. Yet our study shows how the region has an impact on global goals such as the Paris Agreement and, we hope, draws attention to the crisis already unfolding in the far north of our Planet.”says Robbie Mallett, researcher at the University of Manitoba (Canada), in a press release from UCL.
Towards continued high-speed warming of the Arctic
The Arctic, in fact, has already warmed by 2.7°C since the pre-industrial era. And in the region, warming is only accelerating. Models project that a 2°C increase in global temperatures would lead to warming of 4°C in the Arctic and even 7°C over the winter period. With, one imagines, serious consequences for local populations and ecosystems.
