This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.

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.
