Breaking: Concerns rise for Great Barrier Reef health as corals start to bleach

Corals in the far north of the Great Barrier Reef have started to bleach, leaving the federal government's lead reef agency at a state of "heightened alert" about the prospect of a mass bleaching event unfolding over the next two to four weeks.

The current forecasts for the next few weeks "are giving us a heightened risk of a mass bleaching event", he said, adding the threat may peak in the second week of March or later.While the arrival of widespread rain, thunderstorms or a cyclone could disrupt that build-up of heat, meteorologists are not predicting any major weather event, Dr Wachenfeld said.

Dr Wachenfeld said corals would typically start bleaching at about 30-50 degree-heating days, and would begin to die at 50-70 such days. If temperatures remain at about 3 degrees above average, those regions would accumulate 21 degree-heating days per week.While it is too early to declare specific areas to be as risk, inshore reefs in the central and southern parts of the Great Barrier are now accumulating heat stress at a rapid rate.

Pauline'll fix that

The Great Barrier Reef hysteria gets trotted out again. This is the same fraudulent media outlet responsible this. I didn't realise bread glazes itself when baking.

Relax doomers. The reef where I live is going fine.

GOVT's are still NOT taking ENOUGH notice of our GREATEST TOURIST attraction!! 😡😠🤪😡

this so called bleaching is a normal part of the cycles of reef life...I lived there for 16 years ..after every Cyclone the wave action wash off the protective 'slime' and they die back but this type of coral return quickly thereafter.they don't tell you this..why?

How is the $440,000,000 going Great Barrier Reef Fund

There will be a tipping point where the reef simply will not bounce back. Let’s just be done with it. Let’s mine, pollute, remove vegetation and wildlife for jobs. Let’s see how that will turn out in the long run for our kids.

FFS, Give this a rest. It's been the end of the GBR my whole 52 yrs. Every time it comes back. It's a natural cycles idiots.

gov is more worried about coal jobs than tourism When the reef is dead there'd be nothing to show off for tourism which is earning billions


If coral is affected by worming water temperatures, WHY is coral growing faster in higher temperatures North of Australia? 2 James Cook University study found 100% climate change is making fish loopy Hmm 8 Studies found James Cook University was WRONG
