‘Most of it was dead’: scientists discover one of Great Barrier Reef’s worst coral bleaching events
GuardianJUL 2024
The scientific evidence strongly indicates that human-induced climate change is responsible for the increase in ocean temperatures, posing an "existential threat" to the planet's unique natural wonder, the coral reefs. New data indicates that the oceans are currently experiencing the highest temperatures recorded in at least 407 years. The only way to preserve reefs is through rapid reductions in greenhouse gas emissions.
Most scientists agree that climate change is the cause of rising ocean surface temperatures. However, this does not explain why there is a sudden heat surge now. Potential variables include El Nino, random weather events, and reduced sulfur emissions from ships. There is also a possibility that random chance plays a role. Chaotic weather systems may reduce ocean cloud cover, leading to an increase in solar radiation and ocean warming. To establish certainty, further research is required.
There is a 50% chance global warming will be 2.88 degrees Celsius by 2100, according to the Metaculus prediction community.
