New Study: Coral Bleaching ‘Repeatedly Occurred’ Throughout The Warmer-Than-Today Mid-Holocene
By Kenneth Richard on 18. January 2021
Mid-Holocene South China Sea maximum temperatures were ~3.5°C warmer (33.5°C vs. today’s 29.9°C) about 5000 yrs ago, when corals experienced an “optimum coral growth periodâ€. There were “numerous coral bleaching episodes†even when temperatures weren’t as high, as coral bleaching is naturally occurring.
Key points from a new study (Wang et al., 2021) that throws cold water on the claims that modern coral bleaching is unprecedented, unusual, or unnatural.
• “Compared with the average Sr/Ca-SST of the 1990s, the Sr/Ca-SST between 6800 and 5000 B.P. was 0.9°C–0.5°C higher.â€
• “A warmer climate makes the mid-Holocene an optimum coral growth period when corals grew abundantly (Clark et al., 2018; Yan et al., 2019).â€
