Contrary to what Judah Cohen says, the Polar Vortex theory, which argues that a warming Arctic causes a collapse of the "polar vortex" and leads to bitter cold snaps in North America and other places, has been refuted by the Journal Nature.
According to the No Tricks Zone Article:
For example a recent paper appearing in Nature titled "Weakened evidence for mid-latitude impacts of Arctic warming", authored by Blackport et al, refutes this highly fantasy-rich hypothesis pitched by the two PIK scientists.
The Nature article writes:
Jennifer Francis, whose seminal work proposed that Arctic warming was leading to a wavier jet stream, predicted in 2014 that "within a few years, as Arctic amplification continues, we will have enough data to know whether or not we’re rightâ€6.
So, six years on, what has changed? Arctic amplification and sea-ice loss have indeed continued (Fig.1). But predictions of a more negative Arctic Oscillation, wavier jet stream, colder winters in mid-latitudes or, more specifically, in Eurasia, and more frequent and/or widespread cold extremes have not become reality (Fig.1).
Cold waves have been decreasing
Other experts have also noticed what PIK is doing here. Dr. Roy Spencer wrote at his blog in 2019 that U.S. cold waves have been decreasing, thus contradicting the PIK:

"The trend is markedly downward in the most recent 40 years (since 1979) which is the earliest we have reliable measurements of Arctic sea ice from satellite microwave radiometers (my specialty),†Spencer noted.
"Made to fit where they don’t fitâ€
