From the images you share, I can see that it has been a cold winter across large parts of Europe. It has been cold in Norway as well. When cold, stable winter weather lasts for several weeks with little wind, layers of snow and ice build up on spruce trees, turning them into sculptures. This is a typical winter climate for inland eastern Norway, but with a more variable climate, there has not been much snow on the trees since 2023.
