“During the ice age sea level was 120 meters lower than today and much of what is now the North Sea in the waters between England and Norway was at that time forest,” Professor Kullman told Aftonbladet. Winds and low temperatures made Old Tjikko “like a bonsai tree…Big trees cannot get as old as this.”
