- 1Corals Face Existential Threat as Super El Niño Heats Oceans▼Corals Face an Existential Threat as the Super El Niño Heats Up
Conservationists warn that the current super El Niño is pushing ocean temperatures to levels that could trigger mass coral bleaching and death on reefs worldwide. Rising heat stress is described as an existential threat to coral ecosystems, which support vast marine biodiversity and coastal livelihoods. Environmental groups are urging attention to the accelerating damage as sea surface temperatures break records.
- 2Millions of tyres dumped for artificial reef became an ocean disaster▼On a site the size of 27 football fields, 2 million of these were dropped in the ocean to create an artificial reef – instead, it became a disaster
Around two million tyres were dropped onto the seabed on a site the size of 27 football fields in an attempt to create an artificial reef. Instead of attracting marine life, the project became an environmental disaster, as the tyres failed to form a reef, scattered across the ocean floor, and leached toxins. The scheme is now widely cited as a cautionary tale about large-scale marine engineering projects.
