At the start of last year, we learned that the bleaching of the Great Barrier Reef, cause by global warming, had killed 35 % of corals in its northeastern part.

Thanks to the help of scientists and divers who captured images of the corals during the year, we can sadly see that the bleaching is still happening and the corals are still dying.

What is coral bleaching?

It's the warm water temperature (cause by global warming) which pushes the corals to expel the algae giving them their colours and nutrients. With the algae, the corals become white.

If the water temperature gets colder and the algae come back, the coral can often repair itself. But if it doesn't happen, the coral will die.

According to the Climate Council, an independent organisation fighting global warming, we have to stop coral bleaching now or the Great Barrier Reef could disappear forever.

The only durable solution is an international effort against global warming.
