Most corals in the Arabian Gulf could be wiped out this century because of the continued warming of the seas, a new global analysis has indicated.
According to the research, coral cover in the Gulf between 2090 and 2099 is expected to be between 75 and 100 per cent less than it was between 2010 and 2019.
While the forecasts vary according to future greenhouse gas emission levels, the study calculates that under a “middle-of-the-road” scenario, coral cover globally will decline by about 58 per cent by the end of the century.
The study also found that corals in the hottest parts of the world will not be able to expand fast enough into cooler areas to cope with the damage they will experience from the warming of the oceans.
Writing in Science Advances, the scientists said that “the most severe declines in coral cover will likely occur within 40 to 80 years”, but that large-scale expansion of coral reefs into cooler waters to compensate for this “requires centuries”.
Some regions, such as the southern coast of Australia, are forecast to see increases in coral cover, but most will see a decline, with the Arabian Gulf among the hardest hit.
The study’s first author, Dr Noam Vogt-Vincent, of the University of Hawaii at Manoa, told The National that it was “well-established that coral reefs are facing a precipitous decline over the coming decades” and this is being observed in multiple “bleaching” events, where high temperatures make coral expel algae that live inside them.
Corals face growing threat
“As the ocean warms, conditions suitable for reef formation will shift away from the tropics,” he added. “It was previously thought that parts of the subtropics and temperate seas might be able to act as ‘refugia’ for tropical coral species, possibly allowing them to avoid extinction as they experience catastrophic losses in the tropics.
“Our study suggests that, although coral range expansion will eventually occur, it will probably take centuries, which is far too slow for these new higher latitude environments to act as refugia, given that they’re already threatened.”
He said that the problem was not that coral larvae could not reach new environments, but that their growth in numbers was too small for them to develop into larger populations that could sustain themselves.
While the study forecasts that most coral in the Arabian Gulf will be lost this century, Dr Vogt-Vincent said caution should be exercised when interpreting the finding, partly because the model looks at global-scale changes and as the area has extremely high temperatures, the corals are not typical of the Indo-Pacific region.
The new study, Anthropogenic climate change will likely outpace coral range expansion, is also written by scientists from the University of New Hampshire in the US and Victoria University of Wellington in New Zealand.
The Arabian Gulf is “very likely to continue warming as a result of climate change”, said Dr Diana Francis, an assistant professor and head of the environmental and geophysical sciences lab at Khalifa University in Abu Dhabi.
“Recent studies have shown that the Gulf has warmed by approximately 1.0 to 1.5 °C over the past 40 to 50 years,” she said.
She said that the rate of warming in the Arabian Gulf was faster than the global average because it was shallow, semi-enclosed and received much sunlight.
As well as making seas warmer, climate change is also causing them to rise, through expansion of the water and the melting of ice sheets and glaciers.
Prof John Burt of New York University Abu Dhabi, who was not involved in the latest study, but who researches corals around the UAE, said that the more that range expansion of corals was studied, the more it became apparent that “these were this was “not sufficient to keep pace with the impacts of climate change in the tropics”.
He said that only a limited range of coral species, typically more “generalist” types adapted to a wider range of environments, could make the leap to new environments.
“We are not replacing the diversity or functioning of these amazing tropical ecosystems through range expansion,” he said.
“The present paper adds a further nail in the coffin for this line of thought by showing the rates of expansion are only a fraction of what is needed just to replace the total amount of live coral that will be lost on tropical reefs under climate change, not even considering species diversity.”
He said that while Arabian Gulf corals were the most heat-tolerant in the world, they “are not immune to climate change”.
“Recent marine heatwaves and global-scale bleaching events have caused the loss of over 80 per cent of corals from many regional reefs in the past decade alone,” he said.
Taking action
Efforts are being made to protect corals, with Abu Dhabi having recently revealed plans to plant millions of coral colonies across more than 900 hectares.
The initiative is led by the Environment Agency Abu Dhabi, which said its efforts had seen it restore more than one million colonies.
Dr Burt and his colleagues are looking at selective breeding to produce heat-tolerant coral larvae, an approach that could lead to the production, he said, of millions of offspring better able to cope with higher temperatures.
“However, unless we get CO2 emissions under control, the long-term vulnerability of even these robust individuals in the wild remains an open question,” he said.
Researchers say that reducing other factors that stress corals, such as pollution and overfishing, can have a positive effect on reefs, but Dr Vogt-Vincent said that such measures alone were not enough to protect these ecosystems.

How the bonus system works
The two riders are among several riders in the UAE to receive the top payment of £10,000 under the Thank You Fund of £16 million (Dh80m), which was announced in conjunction with Deliveroo's £8 billion (Dh40bn) stock market listing earlier this year.
The £10,000 (Dh50,000) payment is made to those riders who have completed the highest number of orders in each market.
There are also riders who will receive payments of £1,000 (Dh5,000) and £500 (Dh2,500).
All riders who have worked with Deliveroo for at least one year and completed 2,000 orders will receive £200 (Dh1,000), the company said when it announced the scheme.

Key recommendations
- Fewer criminals put behind bars and more to serve sentences in the community, with short sentences scrapped and many inmates released earlier.
- Greater use of curfews and exclusion zones to deliver tougher supervision than ever on criminals.
- Explore wider powers for judges to punish offenders by blocking them from attending football matches, banning them from driving or travelling abroad through an expansion of ‘ancillary orders’.
- More Intensive Supervision Courts to tackle the root causes of crime such as alcohol and drug abuse – forcing repeat offenders to take part in tough treatment programmes or face prison.

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

TERMINAL HIGH ALTITUDE AREA DEFENCE (THAAD)
What is THAAD?
It is considered to be the US's most superior missile defence system.
Production:
It was created in 2008.
Speed:
THAAD missiles can travel at over Mach 8, so fast that it is hypersonic.
Abilities:
THAAD is designed to take out ballistic missiles as they are on their downward trajectory towards their target, otherwise known as the "terminal phase".
Purpose:
To protect high-value strategic sites, such as airfields or population centres.
Range:
THAAD can target projectiles inside and outside the Earth's atmosphere, at an altitude of 150 kilometres above the Earth's surface.
Creators:
Lockheed Martin was originally granted the contract to develop the system in 1992. Defence company Raytheon sub-contracts to develop other major parts of the system, such as ground-based radar.
UAE and THAAD:
In 2011, the UAE became the first country outside of the US to buy two THAAD missile defence systems. It then stationed them in 2016, becoming the first Gulf country to do so.

Quick pearls of wisdom
Focus on gratitude: And do so deeply, he says. “Think of one to three things a day that you’re grateful for. It needs to be specific, too, don’t just say ‘air.’ Really think about it. If you’re grateful for, say, what your parents have done for you, that will motivate you to do more for the world.”
Know how to fight: Shetty married his wife, Radhi, three years ago (he met her in a meditation class before he went off and became a monk). He says they’ve had to learn to respect each other’s “fighting styles” – he’s a talk it-out-immediately person, while she needs space to think. “When you’re having an argument, remember, it’s not you against each other. It’s both of you against the problem. When you win, they lose. If you’re on a team you have to win together.”
