When a Reef is Bleached, It is Bleached: No Matter What Politicians May Prefer

Bleaching events represent very serious damage to coral organisms and the reefs they construct. These events are also, of course, devastating to the myriads of other animals that make the reefs their home. Australia's iconic Great Barrier Reef is now undergoing its 6th mass coral bleaching event (https://www.theguardian.com/environment/2022/mar/25/we-need-action-immediately-great-barrier-reef-authority-confirms-sixth-mass-coral-bleaching-event). No areas, on an aerial survey along a 1200 k stretch, had escaped the bleaching event. Bleaching is routinely followed by death of the coral organism. Bleaching events are triggered by exceptionally elevated local temperatures. There is also no doubt that human-generated releases of 'greenhouse gases', intensify global heating and produce consequent climate change. You can't have a Great Barrier Reef and massive extraction/exporting of non-renewable energy sources.
