Summer temperatures spark fears for Gulf coral reefs



With summer temperatures in the Arabian Gulf generally beyond the tolerance threshold of many coral species, forecasts of unusually warm seas this year are being met with trepidation by marine scientists.

Climate experts have predicted a high likelihood of extreme warming of the water this year because of the El Nino Southern Oscillation, a cyclical periodic shift in the Pacific Ocean that affects weather around the world. In 1997-1998, the phenomenon caused elevated water temperatures in many parts of the world, resulting in large-scale coral die-offs, known as coral bleaching.

In the Arabian Gulf, the highest magnitude of coral bleaching ever was observed, said Dr John Burt, an associate professor of biology at New York University Abu Dhabi (NYUAD). “We lost 90 per cent of the live coral in many of the reefs,” said the school’s head of the marine biology laboratory. “That had a devastating impact on reefs here and in the wider region. The reefs are still recovering.”

Warnings of a significant increase in water temperature this year have raised the concerns.

“Virtually all of the models were predicting a 90 per cent chance of an extreme El Nino event this year,” said Dr Burt.

During routine monitoring of local coral sites earlier this summer, Dr Burt recorded a higher than usual maximum sea temperatures of 32°C in the Gulf of Oman and 34°C in shallower waters near Abu Dhabi. Such temperatures were not unusual for the region at this time of year.

“It has not gone the way they thought it would,” he said, adding that experts were predicting a 60 to 70 per cent chance of moderate to strong warming.

Dr Burt and his associate, Dr Emily Howells, have also been monitoring reefs in Kuwait and Qatar. Their observations showed slightly higher water temperatures in Fujairah where some bleaching of corals was found and reefs were at risk.

Overall, however, a warming event capable of causing mass coral damage and die-off was unlikely.

“We are keeping an eye on things in case they change,” said Dr Burt, noting that August and early September were the highest-risk months for coral reefs.

Coral lives in a symbiotic relationship with marine algae, known as zooxanthellae. Algae lives in the coral tissue, which otherwise would be mostly transparent. Like plants, algae uses sunlight to photosynthesise, producing sugars the coral needs for sustenance.

Heat stress disturbs this symbiotic relationship. Around the world reefs thrive at temperatures of about 28°C. If the temperature is higher this can disturb the algal photosynthesis inside the coral tissue, resulting in the production of damaging oxygen radicals.

When the temperature rises above a certain threshold, coral starts expelling the algae from its tissue. Coral bleaching, as the phenomenon is commonly referred to, occurs when the white coral skeletons shine through the coral tissue, deprived of algal pigments. Bleached coral can sometimes recover but in many cases it dies.

In Australia, coral starts to bleach if the water reaches 31°C. In the Arabian Gulf, it starts at 35°C to 36°C.

While it is impossible to control natural fluctuations in water temperatures, governments can help to protect coral by ensuring additional stress factors are kept at a minimum, Dr Burt said.

“It is important to reduce any man-made stressors resulting from coastal development, nutrient input and intensive [scuba] diving.”

Du Plessis plans his retirement

South Africa captain Faf du Plessis said on Friday the Twenty20 World Cup in Australia in two years' time will be his last.

Du Plessis, 34, who has led his country in two World T20 campaigns, in 2014 and 2016, is keen to play a third but will then step aside.

"The T20 World Cup in 2020 is something I'm really looking forward to. I think right now that will probably be the last tournament for me," he said in Brisbane ahead of a one-off T20 against Australia on Saturday.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.

Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.

Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.

Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.

“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.

Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.

From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.

Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.

BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.

Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.

Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.

“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.

Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.

“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.

“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”

The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Is it worth it? We put cheesecake frap to the test.

The verdict from the nutritionists is damning. But does a cheesecake frappuccino taste good enough to merit the indulgence?

My advice is to only go there if you have unusually sweet tooth. I like my puddings, but this was a bit much even for me. The first hit is a winner, but it's downhill, slowly, from there. Each sip is a little less satisfying than the last, and maybe it was just all that sugar, but it isn't long before the rush is replaced by a creeping remorse. And half of the thing is still left.

The caramel version is far superior to the blueberry, too. If someone put a full caramel cheesecake through a liquidiser and scooped out the contents, it would probably taste something like this. Blueberry, on the other hand, has more of an artificial taste. It's like someone has tried to invent this drink in a lab, and while early results were promising, they're still in the testing phase. It isn't terrible, but something isn't quite right either.

So if you want an experience, go for a small, and opt for the caramel. But if you want a cheesecake, it's probably more satisfying, and not quite as unhealthy, to just order the real thing.
