It has long been believed that mistletoe was only grown in Switzerland in areas at an altitude below 1000 meters above sea level.
A scientist from the Federal Institute of Forest, Snow and Landscape Research (WSL), however, found copies of the mistletoe at altitudes up to 1500 meters. This is a direct consequence of global warming. The climate has warmed considerably over the last century. In Switzerland, the increase in temperature was much more marked than for the world average: only in the 30 last year, the temperatures have increased by 1,5 degrees in the country. During the last 100 years, the limit altitude of the mistletoe distribution area has increased by at least 250 meters on average. This is apparent from a comparison with a study conducted in 1910.
