I agree, Siberian cold due to changed flows of different currents seems more likely as the end result due to climate change for the Nordics rather than increased temperatures.

Increasing temperatures now does not equal increased temperatures later, when the system has stabilized again.

I'm not saying it will happen, just that it seems more likely with what the current data seems to imply, my current information is from some pop culture article though, so I'm the first one to agree that that information might be wrong.
