Climate change is the Great Barrier Reef’s biggest threat, causing rising sea temperatures, ocean acidification, and extreme weather events. The mass coral bleaching we are witnessing on the Great Barrier Reef is the literal effect of climate change.
The reef’s greatest threats
David Attenborough highlights the real threats to the reef today.
Our biggest threat
- 11 of the 12 hottest years have been since 2000
- 90% of the excess heat trapped by greenhouse gases is stored in the oceans
- 6°C rise in global average temperatures by the century’s end if we don’t act
Ever increasing waste
Tons of plastic waste end up in our ocean every year; smothering coral and killing wildlife. But it’s not the only form of waste devastating our reef. Sediment run off, which is of a result of agriculture, urban development and deforestation, ruins our reef’s water quality. This makes our reef more vulnerable to local stresses, like the crown-of-thorns starfish.
- 236,000 tonnes of micro plastic enter our oceans each year
- 93% of material we produce ending up in landfill, atmosphere and our oceans
- 80% of the material dumped at sea is dredged material
Apathy is the enemy
Too many of us have responded to reef’s threats with apathy rather than action. While the dangers are real and immediate, there is hope. But it is critical that more of us start taking action now.
- 26 Billion tonnes of emmissions must be cut by 2030 to limit warming to 1.5 degrees
- Over 50% of corals on the Great Barrier Reef have been lost since the 1980’s
- 29% of shallow water corals died from the bleaching in 2016
Rebuilding the reef
Help us get to 5000 Citizens! Encourage others to get involved, including family, friends, colleagues and local government. The more citizens, the more chance the Reef has.
