This is an interesting article and a lot of what was talked about is correct, this wasn't pushing any agenda, it's just the conclusion isn't quite accurate. The warming of the arctic does indeed push colder temperatures south, and there's an area int he north Atlantic that has seen drops in average temperature in recent years. This process may in fact have been part of how ice ages started in the past.
The incorrect conclusion that we are headed for an ice age that they came to was likely based on a lack of the information we have now. Namely the fact that the increase in temperature isn't just part of the regular cycle of heating and cooling, we're at the top of a heating trend, but the increase of greenhouse gasses is driving temperatures up more than a process like this will cool it down. There'll have been and likely will continue to be some colder winters in the northern hemisphere for a bit as the process starts to kick in, but the overall temperature trend is still getting warmer and isn't going to stop for something like this.

Here's an interesting map to see average temperature change in different regions. https://ichef.bbci.co.uk/news/660/cpsprodpb/12DA7/production...
