A communications report states that 18 sites worldwide have a critical point of view.
Australia’s defense status for Australia’s Great Barrier Reef has dropped from “significant concern” to “critical” due to the increasing effects associated with climate change, a new report has found.
The International Union for Conservation of Nature (IUCN) World Heritage Outlook 2020 report states that the world is in a state of conservation. 252 natural world heritage sites are enough to protect them in the long run. Coral bleaching occurs when the water is too hot and the algae expel the corals from their tissues causing them to turn completely white.
The decline in corals has led to a decline in the population of certain marine species, the researchers said. The most extensive rocks in the world, contains more than 1,500 species of fish.
One-third of natural world heritage sites are currently at risk from climate change, the IUCN report said.
According to the report, warmer temperatures have increased the spread of invasive species in protected areas of South Africa’s Cape Floral region, and in 2019 and 2020, the Pentanal Conservation Area in Brazil was severely damaged by wildfires. In addition, rapid melting of part of the Kluen Lake in the Yukon into the Caskavulsh Glacier has altered river flow, leading to declining fish populations.
Since 2017, the defense appearance of 16 sites has changed dramatically, while only eight have improved, and threats are expected to continue, according to the report.
Climate change is the No. 1 threat to natural world heritage sites. In 2014, the IUCA identified climate change as the most likely potential threat, and in 2017, it became the fastest growing threat. Climate change remains the “most prevalent current threat” in 2020, and in 83 of the 252 sites it is classified as a “high” or “very high” threat, the report said.
After climate change, the next two significant threats to these natural sites are invasive alien species and tourist influences.
The report found that in addition to the Great Barrier Reef, the islands and protected areas of the Gulf of Mexico in Mexico have also entered the critical range. It was added to the ICC’s Danger World Heritage List in 2019 due to its proximity to a local herb, which the World Wildlife Fund describes as “the world’s rarest marine mammal”.
There are currently 18 sites on the crucial list, including the Everglades National Park in Florida and the tropical rainforest in Indonesia.
IUCN Director General Bruno Oberle said in a statement that the world’s heritage sites are among the most valuable in the world, and we are committed to protecting future generations. “The IUCN World Heritage Outlook shows that natural , From shrinking glaciers to coral bleaching to increasingly frequent and severe fires and droughts. As the international community defines new objectives for conserving biodiversity, this report urgently indicates with which we must address the environmental challenges on a planetary basis. “
