If Scandinavia is anything like Canada, the Pine Beetle.
We need a week or two at -40C (fun fact, -40C is roughly equal to -40F) to really thin them out. We haven't been getting that cold weather, so large numbers of them make it through the winter, and then ravage the trees.
It's related to the dramatic increase of forest fires in Western Canada, because dead trees dry out, provide little coverage to the area they're in (which lets the area dry further), and then burn very easily. All it takes is a lightening strike or some idiot deciding to violate a burn-ban, and then everything goes up.
I've heard the warm weather has led to a "tick-pocalypse" and resurgence of ticks and mosquitoes, particularly on Ontario and Quebec. I don't know about termites, but wouldn't be surprised if the warm weather is doing a poor job suppressing them.
