The harmful coral pale has already registered a large part of the global reefs. An initiative that the International Coral Reef Initiative (ICRI) is now warning about the far -reaching effects. According to their information, this is the fourth global Blade event since 1998.
The condition of the coral reefs is becoming increasingly dramatic. The harmful coral pale now has 84 percent of all reefs, the ICRI said. The current crisis started in 2023 and is due to the warmer oceans. If it ended, it would be unclear, it said. However, it surpassed the size of the bleach from 2014 to 2017, which struck around two -thirds of the global reefs.
“We may never experience that the heat stress that causes the bleaching agent falls under the threshold that causes a worldwide event,” said Mark Eakin, director of ICRI. “We are dealing here with something that has completely changed the face of our planet and the ability of our oceans, life and livelihood.”
Coral Reef Home of 25% of all marine animals
In the past year, the warmest has been hottest since the start of the records, who also significantly warmed up the oceans of the world. In 2024, the average annual surface temperature of the oceans reached a record of 20.87 degrees Celsius away from the Poles.
Heating the oceans is fatal for corals. With heat stress they drop small algae that they have to live. As a result, they turned out to die and die. In the past 30 years, half of the corals have disappeared in the Australian Great Barrierveer.
Riffe protects coasts against erosion and storm
The reefs are an indispensable habitat for marine animals, protect kisses against erosion and storms and also have a high value for tourism. Coral reefs bear the nickname “rain forests of the sea” because they house a large biodiversity. An estimated a quarter of all marine animals can be found in, on and around coral reefs.
