According to a World Heritage Outlook released last month by the International Union for Conservation of Nature and Natural Resources, the outlook for the Everglades is "critical" and is the only site of 11 sites assessed in the United States to be designated as such. The site keeps the same critical designation that it received the last time IUCN assessed the sites in 2014.
The Switzerland-based nonprofit assesses 241 natural wonders around the world from the Great Barrier Reef off Australia to California's Redwood National Forest. Of those assessed this year, 17 were rated critical and all primarily a result of human-caused climate change, among other causes.
"Potential threats, including hurricanes, climate change, and ocean acidification to the site are a high threat overall and are potentially being realized already," the report notes.
