These “juhyo,” or ice or snow monsters, are naturally formed by ice and snow, encasing conifer trees spread across Japan’s northern mountains. They’re threatened by climate change. Researchers have tracked a steady deterioration of the juhyo — both in the acreage they cover and the length of the season in which they can be seen — because of warming temperatures that melt the snow earlier and at higher elevations. The trees are also being ravaged by moths that gobble up their needles and a species of bark beetles that have been killing otherwise healthy trees in the last 5 years. Fumitaka Yanagisawa, a professor of geochemistry who studies the #juhyo at Yamagata University, said he’s worried about greenhouse effects. “By the end of the century, the juhyo will disappear from earth.” @jameswhitlowdelano shot these photos in Yamagata Prefecture.
