96% of the world's coral reefs are in danger of extinction... IUCN warns at UN biodiversity conference
A study by the International Union for Conservation of Nature (IUCN) announced that 96% of the world's coral reef ecosystems are in serious danger of extinction and could collapse within 50 years due to climate change and rising sea temperatures.

Coral reef ecosystems around the world are facing the risk of devastating bleaching and extinction due to climate change and rising sea temperatures.
Caused by rising sea temperatures and heat waves due to climate change
(Seoul = Yonhap News) Reporter Hyun Young-bok = Research has shown that the coral reef ecosystem, which has the highest biodiversity in the world, is at risk of collapse within 50 years due to rising sea temperatures and heat waves caused by climate change.
According to the Associated Press on the 22nd (local time), the International Union for Conservation of Nature (IUCN) announced at the United Nations (UN) biodiversity conference held in Albania that day that 96% of shallow-water coral reef ecosystems are already in serious danger of extinction and could disappear by 2075.
IUCN conducted the first coral reef ecosystem red list assessment targeting 127 tropical and subtropical ecoregions and 188,362㎢ of coral reef areas around the world and released these survey results.
In this study, the world-famous Great Barrier Reef in Australia, the Coral Triangle in the Western Pacific and Southeast Asia, and the Red Sea coral reefs were all found to be in serious danger of extinction.
“Coral reefs have shown remarkable resilience even in the face of devastating bleaching events,” said Mishal Gudkar, who led the study. “We must do everything we can to ensure that coral reefs will survive into the future.”
Climate change has been identified as the most persistent threat factor causing the collapse of coral reef ecosystems.
In another research report published in the academic journal Nature a week ago, IUCN also revealed that 44% of the coral fish species that form coral reefs are at risk of extinction due to climate change.
Coral reefs, known as the 'rainforests of the sea', are home to a quarter of marine life and also serve as a buffer zone that protects the coast from coastal erosion and storms.
“We must ambitiously reduce greenhouse gas emissions and work to protect and restore coral reef ecosystems,” said IUCN Director-General Gretel Aguilar. “We must also continue to invest in resilient coastal ecosystems and the communities that depend on them.”

![[Weather] Heavy rain in the southern region on Sunday… More than 200 mm in three days in Jeju mountainous area](/api/img?u=https%3A%2F%2Fimg.yna.co.kr%2Fphoto%2Fyna%2FYH%2F2026%2F10%2F24%2FPYH2026102402700005600_P2.jpg&w=320&q=72&f=webp)
On Sunday, the 25th, it was mostly cloudy across the country, and heavy rain was forecast in the southern region and Jeju Island. Heavy rain of up to 200 mm or more is expected to fall in the mountainous areas of Jeju Island.

While Typhoon No. 30 'Champi' was moving north, heavy rain and strong winds fell on Jeju Island for two days, causing flooding damage, flight cancellations and delays, and passenger ship restrictions. Additional rain of 80 to 150 mm was forecast until the day after tomorrow morning.

The Ministry of Public Administration and Security raised the storm and flood disaster crisis warning for Jeju and the southern coastal region to 'caution' and dispatched an on-site situation management officer as Typhoon No. 30 'Champi' moved north.

On the 24th, the entire country will be mostly cloudy, with heavy rain expected to fall mainly in the southern region and Jeju Island. Heavy rain of 20 to 30 mm per hour is expected on the southern coast and Jeju Island, and caution is required due to high waves caused by coastal swells.

As of 8 p.m. on the 23rd, the Korea Meteorological Administration announced that a strong wind advisory was in effect for the Jeju Island mountainous region, Seogwipo City, and some areas of Jeju City, and that a heavy rain advisory was maintained for the Jeju Island mountainous region, the mid-mountainous area of Seogwipo City, and the southern part of Seogwipo City.

Heavy rain, strong winds, and swell waves are expected throughout the weekend due to the influence of Typhoon No. 30 'Champi' in Jeju and the southern region. Heavy rain of up to 250 mm or more is expected to fall in mountainous areas of Jeju.
