It’s been a bad year for global warming propagandists, but fear not: Here comes a polar vortex to make it worse for them.

The unrelenting Arctic blast arrived on Christmas Eve and it remains the holiday houseguest from Hell that won’t leave: Record-breaking cold and snowfall are tormenting the eastern half of the country, and it’s only going to get worse. Weather models predict Americans will ring in the New Year while shivering under the lowest temperatures in 70 years, and the first day of 2018 could set record lows everywhere east of the Rockies.

Folks are being warned about the health risks associated with sub-zero temperatures, which could last beyond the first week of the year and stretch as far south as east Texas. It’s even too cold for the most intrepid thrill-seekers: Cities are canceling the Polar Bear Plunge on New Year’s Day due to inhumane air and water temperatures.
