Restoring the reef represents one of the most significant science and technology challenges in the history of nature conservation.
We might need to ignore climate change right now if only to save our sanity, but it certainly hasn’t been ignoring us.
Coral bleaching last summer was severe and widespread. And for the first time, severe bleaching has struck all three regions of the Great Barrier Reef.
From a scientific perspective, the results are fascinating and world-first. From a personal perspective, what I saw will stay with me for a long time.

Across science, only around half of published results can be successfully replicated. But while this is a serious problem, the proposed public audit looks like a political bid to cast doubt on science.

We all know that climate change is hurting the Great Barrier Reef. But scores of other less-publicised threats also threaten the future of the natural wonder.

It’s official. The outlook for the Great Barrier Reef has been downgraded to “very poor”, and the window to act is closing.
Resilient corals are offering hope for bleached reefs.
How super is a super coral? And what are they super at? Protecting our coral reefs means we need to find out.

Severe coral bleaching may have been the crucial factor in bringing home the reality of climate change for many people.
Bushfires ravaged parts of central Queensland amid heatwaves in November 2018.
Australia's environment took a beating in 2018, as temperatures rose, rainfall declined, the health of rivers and ecosystems worsened, and floods, droughts and bushfires all took their toll.
After repeated bleaching in 2016 and 2017 corals on the Great Barrier Reef are producing far fewer offspring.
Keep slip slop slapping this summer.
Despite bans around the world, there's no empirical evidence sunscreens cause coral bleaching.
Blacktip reef sharks are one of the most common species on the Great Barrier Reef.
Banning fishing in no-take marine reserves on the Great Barrier Reef does not protect sharks as well as received wisdom would tell you.
