After a trillion tons of CO2, the Great Barrier Reef hits record coral cover third year in a row
AIMS, Coral Reef Survey, 2022.
By Jo Nova
Sixty percent of all human CO2 emissions have been emitted since 1985 but today the corals are healthier than ever
In 1985 humans were emitting only 19.6 billion tons of CO2 each year, and now we emit 37 billion tons. In the meantime AIMS have been dragging divers thousands of kilometers over the reefs to inspect the coral cover. These are the most detailed underwater surveys on the largest reef system in the world, and they show that far from being bleached to hell, the corals are more abundant than we have ever seen them.
As Peter Ridd points out, when the reef was doing badly, AIMS was happy to combine the data on the whole reef, so we could lament its demise. But lately AIMS splits it into separate sections and if Peter Ridd didn’t check the numbers, who would know it was a record across the full 2,300 kilometer length of the reef? And that may be exactly the point. As Ridd reminds us, in 2012 the AIMS team predicted the coral cover in the central and southern regions would decline to 5 – 10 percent cover by 2022. Instead the whole reef is thriving at 30 percent.
