No one knows

Dr. Peter Ridd has been exposing the Great Barrier Reef scam for years, losing his job in the process.
He repeatedly attacked the claims of government-funded scientists that the reef is dying rapidly and shows that it is actually thriving.
In this video, he introduces details of how scientists abuse data to “prove” the sudden decline in coral growth after 1990:
To review, this is the basis for the sirens’ claim:

Yes, this is another hockey stick!
Just like the original data, it is constructed by splicing two sets of data.
As Peter Ridd explains, monitoring of the reef ended around 1990. When measurements of coral growth began again after 2005, they used many cores from young corals, which were easier to drill.
Younger corals have different growth rates than older corals used previously. When these young people are taken out of the calculations, the downturn will magically disappear and growth will return to its pre-1990 levels.
