Polarwirbel überquert US

By Jordi Bou

February 17, 2021 - Ein riesiger Wintersturm breitet sich über die südlichen Staaten in US aus, mindestens 30 Menschen sind tot, Millionen sind ohne elektrischen Strom. Das extreme Wetter soll noch bis zum Wochenende dauern.

Blame the polar vortex, a weather pattern that usually keeps to the Arctic, but is increasingly visiting lower latitudes and staying beyond its welcome. Scientists say global warming caused by humans is partly responsible for making the polar vortex's southward escapes longer and more frequent.

More than 100 million people live in areas covered Wednesday by some type of winter weather warning, watch or advisory, as yet another winter storm hits Texas and other parts of the southern Plains, the National Weather Service said.

Around four million customers remained without power in Texas, 1.4m in Houston alone.’
The weather has threatened the nation's Covid-19 vaccination effort. President Joe Biden’s administration said delays in vaccine shipments and deliveries were likely.
