Absolute cockamamy, Hoegh-Guldberg had to backtrack on most of his claims made in the quoted article and Paper.

PROFESSOR Ove Hoegh-Guldberg, of Queensland University, is Australia's most quoted reef expert.
He's advised business, green and government groups, and won our rich Eureka Prize for scares about the Great Barrier Reef. He's chaired a $20 million global warming study of the World Bank.
In 1999, Hoegh-Guldberg warned that the Great Barrier Reef was under pressure from global warming, and much of it had turned white.
In fact, he later admitted the reef had made a "surprising" recovery.
In 2006, he warned high temperatures meant "between 30 and 40 per cent of coral on Queensland's great Barrier Reef could die within a month".
In fact, he later admitted this bleaching had "a minimal impact".
In 2007, he warned that temperature changes of the kind caused by global warming were again bleaching the reef.
In fact, the Global Coral Reef Monitoring Network last week said there had been no big damage to the reef caused by climate change in the four years since its last report, and veteran diver Ben Cropp said this week that in 50 years he'd seen none at all.

The Great Barrier Reef Marine
Park Authority, Queensland Parks and Wildlife Service,
researchers and industry partners completed 374 reef health surveys covering 54 reefs
between 1 Dec 2011 and 30 April 2012.
Overall, survey results indicated a low level of coral stress on the Great Barrier Reef during
summer 2011/12 and autumn 2012. Half of all surveys (52 per cent) recorded no impacts to
reef health.
Of the remainder, 31 per cent of surveys reported one type of reef health impact,
and 17 per cent of surveys recorded more than one type of impact.
Of the surveys that found impacts, physical damage was the most common type found (35 per cent), closely followed
by coral bleaching (31 per cent). Coral disease was noted in 17 per cent of surveys, and less
than 10 per cent of surveys recorded signs of predation from crown-of-thorns-starfish or
Drupella snails. Whilst impacts were recorded on 48 per cent of surveys in the majority of
cases these impacts were mild in severity and unlikely to result in serious or lasting damage.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3053361/While the limited data for the GBR prior to the 1980s suggests that coral cover was higher than in our survey, we found no evidence of consistent, system-wide decline in coral cover since 1995. Instead, fluctuations in coral cover at subregional scales (10100 km), driven mostly by changes in fast-growing Acroporidae, occurred as a result of localized disturbance events and subsequent recovery.
