The government's top Great Barrier Reef scientist says a third mass coral bleaching (珊瑚白化) event in five years is a clear signal that the marine wonder is “calling for urgent help on climate change. Corals can recover from mild bleaching, but severe bleaching can kill corals.
Prof Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University, surveyed 1,036 reefs from a plane over nine days in late March.
The marine park authority also had an observer on the flights. The survey has released maps showing that serious levels of bleaching occurred in 2020 in all three sections of the reef northern, central and southern. Some 25% of the reefs were seriously bleached-meaning that more than 60% of the corals on each reef had bleached.
The Great Barrier Reel has experienced five mass bleaching events-1998. 2002,2016, 2017 and 2020 -all caused by rising ocean temperatures driven by global heating. Hughes said there probably would not be the same level of coral death in the north and central regions in 2020 as in previous years, but this was partly because previous bleaching outbreaks had kill off the less heat -tolerant species The 2020 bleaching was second only to 2016 for severity(严重性), Hughes said.
Dr. David Wachenfeld,chief scientist at the Great Barrier Reef Marine Park Authority, told Guardian Australia "My greatest fear is that people will lose hope for the reef. Without hope there's no action. People need to see these bleaching events, They are clear signals that the Great Barrier Reef is alling for urgent help and for us to do everything we can”.
Measures to improve the ability of recovery of the reef include improving water quality, controlling outbreaks of coral-eating starfish, and research and development to improve the heat tolerance of corals. " However, climate change brings a new scale of impact unlike anything we have seen before. Thus, dealing with the climate problem is the basis for everything else to work,” Wachenfeld said.
