Another alarmist narrative debunked by observations.

Coral coverage was supposed to be existentially devastated by the modern tenths-of-a-degree increases in sea surface temperatures and recurring bleaching events.

However, a new study points to assessments of coral cover percentages in the Great Barrier Reef and concludes is “at its highest since monitoring began in 1985.”

Further, the analysis reveals there is “no consistent correlation between rising temperatures and reduced coral cover,” and that “most corals [are] demonstrating rapid recovery” from bleaching.

The Australian Government also documents significant decadal variability in coral cover, but no overall trend or decline in coral coverage since the early 1980s.
