Sea temperatures reached record levels this week in the latest indication of the large-scale impact of climate change.
The Copernicus Climate Change Service, EU's Earth observation programme, said that average global sea surface temperatures reached 20.96°C – well above normal for this time of year.
It comes shortly after Copernicus and others said that July was set to be the hottest month on record in terms of air temperature.
Here we look at the effects of ocean warming on everything from sea-level rises to coral reef bleaching.
What is happening with ocean temperatures?
Although only 0.01 °C above the previous record set in March 2016, the increase is particularly concerning because it has been set in the month of August.
Ocean temperatures typically peak around March, as was the case in 2016, which makes this week’s high especially anomalous.
There have been marine heatwaves across the globe recently, including off Florida, where sea surface temperatures reportedly climbed as high as 38.4°C in July. The Mediterranean has also seen temperature records broken.
Marine heatwaves are expected to increase in both frequency and severity, with resultant impacts to more vulnerable ecosystems and organisms

“We are seeing that there are marine heatwaves going on around the world,” said Bob Ward, of the Grantham Research Institute on Climate Change and the Environment, part of the London School of Economics.
“There are areas where the temperatures are several degrees higher than normal.”
One factor pushing up sea temperatures is that the world’s climate has entered an El Nino phase, when temperatures tend to be higher than in the opposite La Nina system, which involves cold waters being brought up from the depths of the Pacific.
However, this is not considered sufficient to account for the record temperatures. Heat from deep in the oceans could be coming up to the surface, leading to temperatures that are much higher than normal, scientists have suggested.
What effects does ocean warming have?
Water covers more than 70 per cent of the Earth’s surface and, according to figures published by Nasa, oceans have absorbed 90 per cent of the warming that has resulted from human-induced climate change.
As well as absorbing heat, the oceans also take in carbon dioxide, the main greenhouse gas, and so act as a brake on climate change.
UN figures indicate that oceans have absorbed about a quarter of all CO2 emissions, but warmer water cannot hold as much, which could cause temperature increases to accelerate.
“The functioning of the oceans is critically important to how the planet warms, as is the absorption of carbon into the oceans,” said Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia in the UK.
Heatwaves around the world – in pictures
Rising temperatures also cause oceans to expand, leading to sea-level increases, threatening coastal and island communities. The expansion of water has caused about one third of the sea level rises since 2004, according to Nasa data.
There are other factors linked to the warming of oceans that are causing sea levels to rise.
“It helps to erode and starts to melt the ice shelves around the big land ice sheets in Greenland and Antarctica. The ice sheets, they’re what flow into oceans, leading to more sea level rises,” Mr Ward said.
Warmer waters in the polar regions help to melt sea ice. Mr Ward said the water off of Antarctica is currently abnormally warm, causing sea-ice levels in the region to decline.
Sea ice reflects between 50 per cent and 70 per cent of the sun’s energy, according to the National Snow and Ice Data Centre at the University of Colorado Boulder in the US, while the darker ocean reflects only 6 per cent. As a result, the loss of sea ice contributes to the warming of the climate.
Another effect of warming seas is that higher sea surface temperatures in hotter parts of the world can result in more tropical cyclones.
How are organisms affected by rising sea temperatures?
The current change in marine temperatures “is unlike anything we have seen in the past”, according to John Burt, an associate professor of biology at New York University Abu Dhabi. He added that this has created “unprecedented times” for marine organisms.
“Marine heatwaves are expected to increase in both frequency and severity, with resultant impacts to more vulnerable ecosystems and organisms in the coming two decades,” he said.
Some marine life is moving towards the poles, said Mr Ward, but not all organisms are moving together.
“That causes disruption to the ecosystem,” he said. “For instance, some fish are finding their foodstuff is less common because it’s moved away.”
Dr Burt studies coral reefs and he said that these “are considered the ecosystem most susceptible to current climate change”.
Coral lives in symbiosis with single-celled algae, called zooxanthellae, which Dr Burt said provides more than 90 per cent of its energy. During heatwaves, the coral expels the zooxanthellae and turns white, a process called bleaching.
“If the bleaching event lasts more than a few days to a week, colonies will typically start to die off,” Dr Burt said.
“Sadly, the UAE experienced several extreme bleaching events in recent years – 2017 and 2021 – and we have lost over 75 per cent of corals from many reefs across the UAE.
“My team also noted bleaching beginning last week, and it is now in full effect in Abu Dhabi waters, raising the spectre of another possible mass die off.”
Bleaching, even if not fatal, may increase disease among coral and lower reproductive output, making it harder for it to recover when a portion has died off.
“Obviously, a key mechanism driving all of these temperature changes is CO2, and therefore this adds even more urgency to efforts such as those being discussed at the upcoming Cop28 towards reductions in fossil fuel use,” Dr Burt said, referring to the UN climate change conference to be held in the UAE later this year.
“It's in the hands of our world's leaders to commit to meaningful CO2 reduction targets and to get our planet back in a state we'd be happy to hand over to our children.”
Classification of skills
A worker is categorised as skilled by the MOHRE based on nine levels given in the International Standard Classification of Occupations (ISCO) issued by the International Labour Organisation.
A skilled worker would be someone at a professional level (levels 1 – 5) which includes managers, professionals, technicians and associate professionals, clerical support workers, and service and sales workers.
The worker must also have an attested educational certificate higher than secondary or an equivalent certification, and earn a monthly salary of at least Dh4,000.

FFP EXPLAINED
What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.
What the rules dictate?
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.
What are the penalties?
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.

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.”

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.”
What is cyberbullying?
Cyberbullying or online bullying could take many forms such as sending unkind or rude messages to someone, socially isolating people from groups, sharing embarrassing pictures of them, or spreading rumors about them.
Cyberbullying can take place on various platforms such as messages, on social media, on group chats, or games.
Parents should watch out for behavioural changes in their children.
When children are being bullied they they may be feel embarrassed and isolated, so parents should watch out for signs of signs of depression and anxiety
