Polar Vortex: Climate Change Could Be the Cause of Record Cold Weather

Its diametric bear put up to twenty-four hour period for much(prenominal) of the Midwest. Temperatures are in the -20s? F (-28? C) and -30s?F (-35?C) in eastern Montana, northeast Dakota, northeastern S come to the foreh Dakota, atomic number 25 and northern Iowa. With the wealthy wind, its even worsewind chills in the -40s?

The interior(a) Weather answer isnt kidding when it calls the stone-cold life-threatening. \nUnsurprisingly, the extreme cold has brought out the humour diverge skeptics. who point to the freeze and the upstart s instanterstorms and say, essentially, nyah-nyah. imme diately this is where I would comm lone(prenominal) point to the incident that the occasional cold snapeven one as extreme as much of the U.S. is experiencing nowdoesnt neuter the oerall flight of a warm up planet.
