In southern Sweden the vast spruce forests are starting to die because of the spruce bark beetle. You can see it everywhere now.
Supposedly due to warmer summers.
And new planatation replace spruce by larch or leaf trees.
Luckily they don't seem to affect pine trees, but they have their own climate expectations.
It is actually because of drier summers and monoculture. The more spruce there is the more they beetles there are.
