Ward said the impact of bleaching had been extensive across 16 sites that she visited in the reef’s southern section, affecting coral species that had usually been resistant to bleaching. Some coral had started to die, a process that usually takes weeks or months after bleaching occurs.

“I feel devastated,” she said. “I’ve been working on the reef since 1992 but this [event], I’m really struggling with.”

As do I Dr. Ward, with ever election result reinforcing the deveststation of the orthodoxy and the disregard my fellow citizens have for a livable biosphere.

A program in the United Arab Emirates is growing corals native to the Persian Gulf that have evolved to withstand high temperatures.

I’ve been thinking of how to combine electrified reefs with open ocean aquaculture as a way of helping indigent and at-risk fisher communities to deal with climate change. Of course, there’s no technological solution to social problems, so I still have to consider the social and organizational aspects of using these technologies in indigent fisher communities.

How would you think these technologies could help coastal communities?

On a brisk winter's day in Sydney, most people find the seawater temperature near freezing.

A team of Sydney scientists are getting creative about how to provide these underwater gardens with the best chance of survival against global warming, starting with coral found in Sydney Harbour.

Using these findings, researchers will give corals what a nutritional supplement is to humans, but instead of vitamin C, it's fat.

"If corals can feed well, they've got a better chance at surviving a bleaching event."

"The window for saving the Great Barrier Reef and other reefs in the world is getting smaller and smaller", she cautioned.

Pollution cuts have diminished “ship track” clouds, adding to global warming

Heat-resistant strains of giant kelp are being planted around the Tasman Peninsula in a bid to restore the once great marine forests devastated by climate change.

Baron, who has been diving in these waters for more than 40 years, says the disappearance of the kelp has led to a wider scale collapse of the ecosystem.

With the backing of fashion-designer-turned-climate-entrepreneur Sam Elsom's Sea Forest Foundation, an initiative that hopes to help tackle the climate crisis by protecting and restoring kelp and seaweed, they began the process of planting giant kelp across more than half a hectare.

The water is surprisingly clear, and cold, and as we descend we pass over beds of golden kelp and crayweed, their honey-coloured leaves shifting in the light from above.

"We're facing the loss of kelp forests in Australia within a decade or two. That could still happen, even with what we're trying to do. But if we do nothing, you can guarantee they'll be gone. So I don't think we have the luxury of not trying."
