Daily US Times: A new study shows that increases in extreme winter in parts of the United States are linked to accelerated warming of the Arctic.
The scientists found that warming in the Arctic region ultimately disturbed the circular pattern of winds known as the polar vortex.
This caused colder winter weather to flow down to the US, notably in the Texas cold wave in February.
The authors say that warming in the Arctic region will see more cold winters in some locations.
Over the past 40 years, satellite records have shown how increasing global warming have had a profound effect on the Arctic.
Warming in the Arctic is far more pronounced than in the rest of the world, and has caused a rapid shrinkage of summer sea ice.
Scientists have long been warning and showed concern about the implications of this amplification of global change for the rest of the planet.
This new study indicates that the warming in the region is having a significant impact on winter weather in both East Asia and North America.
The authors of the study show that the melting of ice in the Kara and Barents seas leads to increased snowfall over Siberia and a transfer of excess energy that impacts the swirling winds in the stratosphere above the North Pole.
The heat ultimately causes a stretching of the vortex which then causes extremely cold weather to flow down to the US.
