Coral: Hitting the Rocks?

The US National Oceanic and Atmospheric Administration's (Noaa) 'Coral Reef Watch' is warning that global heating is currently pushing coral reefs, towards a 4th planet-wide mass bleaching event. More than half the world's coral reefs are showing signs of heat stress (https://www.theguardian.com/environment/2024/apr/15/great-barrier-reef-coral-bleaching-global-heating). The Noaa point to the neglect of reefs, on a global scale. It's certain to have a major impact on marine food chains, reducing their productivity. Yet another loss of food for human populations?
