As countries map out strategies to mitigate the devastating impact of climate change on coastlines, one question looms: how much will sea levels rise?
Could Hamdan Street be under a metre or three of water by the end of next century? And when sea levels rise, how quickly will it happen?
The answer lies in the interaction between ice sheets and oceans – yet at the moment, the impact on global sea levels is unknown. To understand what happens at the tumultuous boundary between ice and sea, answers can be found in the abstract.
More than 30 of the world’s top climate change mathematicians met this week at New York University Abu Dhabi Institute for a three-day workshop. Their goal was to develop models that explain how ice sheets and oceans interact at the West Antarctic Ice Sheet – this ice sheet drains into glaciers the size of small countries, like the Pine Island Glacier and the Thwaites Glacier, and its future will determine the future shape of our coastlines.
Over the course of three days, with today the last day, the scientists compared ice sheet models and ocean models with the goal of developing detailed models that combine the two.
“The single biggest uncertainty in future estimates of sea levels is to do with how the ice sheet responds to ocean water and the [majority] of climate models don’t consider that influence at all,” said Dr Ben Galton-Fenzi, a senior research scientist with the Australian Antarctic Division.
“Currently they just have some really simple ways of dealing with the influence of climate change on the ice sheet. So we’re trying to understand in greater detail how the ocean drives the melting of the ice, which is a massive problem.”
It is the joining, or coupling, of models that is the key. Current global climate models cannot simulate sea-level change because few models join the two systems. There are just six models of how oceans work, and another six models of how ice sheets work, and only two models that combine the two systems together.
“If you want to simulate or project sea level rise we need a system that is fully coupled to represent the reality, which doesn’t exist right now,” said Dr Diana Francis, an atmospheric scientist at NYUAD’s Centre for Sea Level Change.
It's not just warmer air but the ocean itself that melts ice sheets. Ice sheets are disintegrating from the bottom up as they come into contact with warm ocean currents. Normally, warm water from other parts of the ocean sinks and only comes into contact with ice sheets after it has cooled. But when there is a lot of meltwater, as is currently the case, then warm and cold water do not mix properly and warm water comes into contact with ice sheets before it has cooled. This creates a feedback loop.
That means if we don't know what the glaciers are doing, we don't know what the oceans will do, and vice versa.

Ice sheet and ocean modelling require different set of physics and pairing the two is no simple task.
“An ice sheet model is something that evolves in a very long time scale, hundreds of years,” said Gustavo Marquez, a physical oceanographer with the US National Centre for Atmospheric Research. “While an ocean model is something that evolves much more quickly. So to have these two things talking to each other, it’s a big challenge and not just computationally."
Winds also must be taken into account. Each system affects the other.
Rising Coastal Seas on a Warm Earth is the third biannual workshop organised by Denise Holland of the Centre for Global Sea Level, led by its principal investigator David Holland.
Despite its evident importance, securing funding for such abstract studies remains a challenge.
“For model inter-comparison projects, people often have to latch it onto other projects in order to get funding for it,” said Ben Hills, a glaciologist and PhD student at Washington University. “To the public, doing some simple idealised tests seems silly but we need them in order to test the models so that we know the physics are working before we can move into real Antarctic simulation.”
It is also far less expensive than research on the ground in the remote polar regions.
More observational data will be gleaned from Dr Holland's upcoming research expedition to the Thwaites Glacier that he will led with Keith Nicholls of the British Antarctic Survey. Theirs was one of eight five-year research projects approval last week by International Thwaites Glacier Collaboration.
Much of the expeditions’s data analysis will take place at labs in Abu Dhabi. While the modelling analysis done from a lab on Saadiyat Island can feel a world removed from the Antarctic, the results will have a very real impact on all of us.

The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.

Basquiat in Abu Dhabi
One of Basquiat’s paintings, the vibrant Cabra (1981–82), now hangs in Louvre Abu Dhabi temporarily, on loan from the Guggenheim Abu Dhabi.
The latter museum is not open physically, but has assembled a collection and puts together a series of events called Talking Art, such as this discussion, moderated by writer Chaedria LaBouvier.
It's something of a Basquiat season in Abu Dhabi at the moment. Last week, The Radiant Child, a documentary on Basquiat was shown at Manarat Al Saadiyat, and tonight (April 18) the Guggenheim Abu Dhabi is throwing the re-creation of a party tonight, of the legendary Canal Zone party thrown in 1979, which epitomised the collaborative scene of the time. It was at Canal Zone that Basquiat met prominent members of the art world and moved from unknown graffiti artist into someone in the spotlight.
“We’ve invited local resident arists, we’ll have spray cans at the ready,” says curator Maisa Al Qassemi of the Guggenheim Abu Dhabi.
Guggenheim Abu Dhabi's Canal Zone Remix is at Manarat Al Saadiyat, Thursday April 18, from 8pm. Free entry to all. Basquiat's Cabra is on view at Louvre Abu Dhabi until October

Dubai works towards better air quality by 2021
Dubai is on a mission to record good air quality for 90 per cent of the year – up from 86 per cent annually today – by 2021.
The municipality plans to have seven mobile air-monitoring stations by 2020 to capture more accurate data in hourly and daily trends of pollution.
These will be on the Palm Jumeirah, Al Qusais, Muhaisnah, Rashidiyah, Al Wasl, Al Quoz and Dubai Investment Park.
“It will allow real-time responding for emergency cases,” said Khaldoon Al Daraji, first environment safety officer at the municipality.
“We’re in a good position except for the cases that are out of our hands, such as sandstorms.
“Sandstorms are our main concern because the UAE is just a receiver.
“The hotspots are Iran, Saudi Arabia and southern Iraq, but we’re working hard with the region to reduce the cycle of sandstorm generation.”
Mr Al Daraji said monitoring as it stood covered 47 per cent of Dubai.
There are 12 fixed stations in the emirate, but Dubai also receives information from monitors belonging to other entities.
“There are 25 stations in total,” Mr Al Daraji said.
“We added new technology and equipment used for the first time for the detection of heavy metals.
“A hundred parameters can be detected but we want to expand it to make sure that the data captured can allow a baseline study in some areas to ensure they are well positioned.”

Skewed figures
In the village of Mevagissey in southwest England the housing stock has doubled in the last century while the number of residents is half the historic high. The village's Neighbourhood Development Plan states that 26% of homes are holiday retreats. Prices are high, averaging around £300,000, £50,000 more than the Cornish average of £250,000. The local average wage is £15,458.
Three ways to boost your credit score
Marwan Lutfi says the core fundamentals that drive better payment behaviour and can improve your credit score are:
1. Make sure you make your payments on time;
2. Limit the number of products you borrow on: the more loans and credit cards you have, the more it will affect your credit score;
3. Don't max out all your debts: how much you maximise those credit facilities will have an impact. If you have five credit cards and utilise 90 per cent of that credit, it will negatively affect your score.
