The parent is drawing their own conclusions from the article. Here is a key quote, but please read the whole article. It is actually quite good.
At this point, it’s time to ask what the heck is going on here. And while there may not yet be any scientific consensus on the matter, at least some scientists suspect that the cooling seen in these maps is no fluke but, rather, part of a process that has been long feared by climate researchers — the slowing of Atlantic Ocean circulation.
The Atlantic ocean's circulation patterns for that area are driven by density differences. Warm water from further south moves north along the surface and when it gets to Greenland it freezes as sea ice. That process greatly increases the salinity, and therefore density, of the remaining water and so it sinks and circulates south again.
This loop is critically important for certain favorable climate features of Western Europe.
If this is in fact what is occurring then this isn't evidence against climate change, it was one of the more extreme predictions OF climate change.
