One year after Dubai floods: How climate change is reshaping the weather and urban landscape
One year ago today, Dubai was brought to a standstill. Cars floated along submerged roads. Malls and schools closed. Flights were grounded. In just 12 hours, 100mm of rain fell – the amount the city typically receives in a year and the heaviest rainfall since records began in 1949. On the first anniversary of the deluge, the question is not whether if it will happen again, but when and how often. Dubai Municipality has responded by announcing this week that it has awarded Dh1.4 billion in stormwater drainage contracts. The contracts fall under the Dh30 billion Tasreef project, Dubai's largest unified stormwater collection system. The projects will serve key areas across the emirate: Nad Al Hamar, the area around Dubai International Airport, Al Garhoud, Al Rashidiya, Al Quoz, Zabeel, Al Wasl, Jumeirah and Al Badaa. They aim to enhance the capacity of the drainage system and increase its discharge capacity by 700 per cent over the next 100 years. The scheme was introduced in the months following the storm and is scheduled to be completed by 2033. Such initiatives aim to change the impact of climate change on the region, with more frequent storms forecast. 'The combination of rising global temperatures and regional climatic shifts suggests that the UAE, including Dubai, may experience similar severe rainfall events more frequently in the future,' Dr Adam Fenech, provost at Canadian University Dubai, told The National. 'This underscores the importance of urban infrastructure and emergency preparedness in mitigating the impacts of such events.' Climate experts say last year's flooding is a clear sign that weather systems across the Gulf are shifting. According to Dr Fenech, Dubai's average annual rainfall has increased by 40 per cent in recent decades, while the wider GCC region has seen a 20 per cent rise over the past 20 years. 'This increase aligns with projections that a warmer atmosphere due to climate change can hold more moisture, leading to more intense rainfall events,' said Dr Fenech, who shared the Nobel Peace Prize in 2007 for his work with the Intergovernmental Panel on Climate Change. He warned that short, intense downpours like those experienced in April 2024 are now more likely, particularly during El Nino years, the name given to when warmer waters in the Pacific shift global rainfall patterns. Scientific analysis suggests that downpours during these years have become 10 to 40 per cent heavier in the region due to climate change. Experts attribute the 2024 flood to a convergence of weather systems. Abdulla Al Mandous, director general of the UAE's National Centre of Meteorology, says last year's storm was triggered by a warm, moisture-laden air mass from the south colliding with a cold upper atmosphere. 'The resulting differential temperatures and humidity levels facilitated cloud formation, particularly the development of cumulonimbus clouds, which are capable of producing intense rainfall due to their vertical development and latent heat release,' Dr Al Mandous told The National. But the deeper issue lies in a climate system that is no longer behaving predictably. Dubai's new stormwater drainage project is designed to address that problem by channelling water more efficiently away from urban centres to prevent surface flooding and reduce the risk of economic disruption. But experts say that infrastructure alone will not be enough. Artificial intelligence is being touted as a key part of the city's adaptation strategy. Naji Atallah, Europe, Middle East and Africa head of construction and manufacturing at Autodesk, says AI can simulate flood events, test urban planning scenarios and process huge collections of data to enable faster, more effective decisions. 'The value of AI lies in its ability to process vast data sets quickly – from rainfall intensity to land use patterns – helping city planners and engineers develop solutions that are both resilient and resource-efficient,' he said. 'As this region continues to urbanise at pace, investing in such smarter infrastructure will be key to mitigating environmental risk while meeting future demand.' 'Dubai's investment in a citywide stormwater network reflects a growing recognition that water resilience is critical to future-proofing our cities,' said Michael Nielsen, regional director at Danish pump manufacturer Grundfos. 'As we witness more frequent and intense weather events across the region, it's no longer enough to rely on conventional infrastructure. Urban water systems must be reimagined to adapt to a more unpredictable climate.' An Abu Dhabi company has created a forecasting system that could change how authorities and businesses prepare for extreme weather. The National Centre of Meteorology told The National that it forecasts about seven days in advance, but the new system from G42 with global chip maker Nvidia is said to increase that capability to 14 days. Antonios Vouloudis, senior director of sustainability and stewardship at NYU Abu Dhabi, told The National that this would provide 'ample time for authorities and businesses to implement necessary measures'. Newton Rebello, marketing director at Inception, a G42 subsidiary, explained that the real value, however, is not in the speed of the forecast, but in the quality of the resolution used to make the prediction. 'Clearer resolution equals better prediction. This is a massive improvement,' he said. Dr Al Mandous said: 'AI-powered weather forecasting has the potential to revolutionise high-quality, high-resolution weather and disaster management solutions, particularly in this accelerating phase of climate change. 'By enhancing prediction accuracy and enabling hyper-local, real-time forecasts, this technology empowers better decision-making and strengthens resilience against climate challenges.' Mr Vouloudis added that such technology 'can enable cities to make informed decisions for smarter urban planning to manage heavy rain, heatwaves and other climate risks'. Such tools could also be used to warn commuters about flooding on their routes, help parents to plan outdoor activities for their children and enable businesses to minimise disruptions. Beyond the UAE, G42 is also exploring the expansion of its technology in climate-vulnerable regions such as Africa, South Asia and South-East Asia.

Air-conditioning fault leaves passengers stuck on plane in Dubai's 47°C heat
Passengers on a British Airways flight from Dubai felt the heat when an air-conditioning fault grounded the plane on a day of record high temperatures. Travellers were subjected to sweltering conditions on board the Boeing 787 plane while it remained at Dubai International Airport for about two hours due to a power failure that prevented cabin airflow and cooling systems from operating. The aircraft was diverted to a cargo area of the airport while repairs were carried out, British newspaper The Independent reported. The flight left Dubai for London after the malfunction was fixed. 'We thank our customers for their patience while we resolved a technical issue with the aircraft,' said a British Airways spokesperson in a statement shared to media. 'Our crew provided water to customers on board and worked hard to ensure our customers remained as comfortable as possible whilst we resolved the issue.' The incident took place on Saturday, when temperatures in Dubai soared to 47°C and exceeded 50°C in other parts of the Emirates. The mercury rose to 51.6°C in the Sweihan area close to Al Ain, a record for the month of May in the UAE. The previous record high of 50.4°C, also in Abu Dhabi emirate, was set the previous day.

Somalia floods kill seven, displace 200 families
10 May 2025 23:33 MOGADISHU (AFP)At least seven people were killed in an overnight devastating flood in Somalia's capital Mogadishu, local government officials said on rains, which started on Friday night and lasted about 10 hours, touched off the floods that displaced more than 200 houses were completely destroyed across various districts of Mogadishu, while six major tarmac roads were also damaged."Seven people died, two of them women," Salah Omar Hassan, the spokesman of the Banadir regional administration, said in a press added, "The floods also swept through the houses of 200 families while destroying six key tarmac roads, which are very important for the movement of transport and people in the capital Mogadishu."A UN report published on April 30 revealed that more than 45,000 people have been affected by flash floods in Somalia since mid-April. The Horn of Africa is one of the regions most vulnerable to climate change, and extreme weather events are becoming increasingly frequent and intense. Somalia was hit by intense floods in 2023. More than 100 people were killed and over a million displaced after severe flooding caused by torrential rains linked to the El Nino weather pattern.

UAE braces for prolonged hot summer with temperatures likely to hit 48°C
The UAE has entered an unusually intense, early heatwave, with temperatures already climbing past 44°C in recent days – a sweltering sign of what experts warn will be a hotter, longer summer. Dr Ahmed Habib at the National Centre of Meteorology told The National that the country is currently gripped by a thermal low pressure system, causing highs to reach between 46°C and 47°C across much of the country − and possibly even nudging 48°C. The intense heat is expected to persist throughout the week. On Monday, the NCM issued a public health warning about the rise in temperatures. 'The air mass is moving from the desert into the UAE, causing temperatures to rise significantly.' said Dr Habib. 'We have been affected by this pressure system since last week, and will continue to be affected by it over the next five days.' UAE summers are arriving earlier and lasting longer, says Dr Diana Francis, climate scientist and head of the ENGEOS Lab at Khalifa University in Abu Dhabi. 'In our paper published in 2024 in Nature Scientific Reports, we looked into the shift in seasons and the changes to their length and found that summer is getting longer, with an early start and late end,' she said. Dr Francis told The National that summer is now lasting on average 10 days longer – and this trend is projected to continue. 'In the future, projections show an increase of the summer season towards six months, with fall and spring seasons shrinking in length.' Her findings are echoed by Antonios Vouloudis, senior director of sustainability and stewardship at NYU Abu Dhabi. 'Yes, the UAE is experiencing higher temperatures earlier in the year,' he said. 'Studies indicate that the hottest months over the past 50 years are occurring closer to the present day, suggesting a shift in seasonal temperature patterns.' During the core summer months of June to September, average temperatures range from 32°C to 37.2°C, with peaks reaching up to 50°C, especially in southern regions. Climate scientists are clear that the UAE's heating trend is part of a wider regional and global pattern − as 2024 was reported as the hottest year on record globally. 'In the past four decades, the region has warmed two times faster than the global average,' Dr Francis said. 'Our projections show a warming of 5°C per decade until the end of the century.' The broader Middle East and North Africa region, Mr Vouloudis says, has been warming at 0.46°C per decade since 1980. 'This trend aligns with regional patterns,' he said. 'These changes are attributed to global climate change, leading to more frequent and intense heatwaves across the region.' Compounding the situation, Dr Francis noted that the typical cooling effect from the El Nino phenomenon is absent this year, intensifying local conditions. As temperatures climb toward the high-40s this year, experts warn that adapting to the realities of a warming climate is no longer optional. Residents are urged to stay hydrated, limit outdoor activity, and adhere to public health advice. 'Extreme heat combined with humidity creates for human bodies conditions very difficult to survive in.' said Dr Francis. Dr Aseel Takshe, chairwoman and associate professor with the department of public health at Canadian University Dubai, told The National that hospitals and emergency services are preparing for an upsurge in heat-related illnesses. 'There is a strong emphasis on public education,' said Dr Takshe. 'Campaigns focus on recognising symptoms of heatstroke and dehydration, encouraging hydration and the use of appropriate clothing, posting reminders and informational materials at workplaces and public areas, and avoiding outdoor activity during peak heat hours.' During hot summer months, the UAE enforces a midday break rule for outdoor workers. Worksites are required to provide shaded rest areas, hydration, and regular breaks. Dr Takshe told said that 'there is an ongoing discussion about stricter enforcement and the possible expansion of these regulations as summers become hotter'. Dr Beatriz Garcia, professor in the law, economics and management at Sorbonne University Abu Dhabi told The National that the increased demand for air conditioning during summertime in both residential and commercial buildings not only elevate electricity consumption in the UAE but also intensifies the load on the grid. "This can potentially lead to challenges in maintaining grid stability and meeting peak demand." To adapt to a hotter, more water-stressed future, the UAE has made significant investment in expanding renewable energy capacity, especially solar, investing in advanced water conservation and recycling technologies. 'The UAE has ensured no water shortages and has prepared a strong infrastructure in case demand spikes,' said Dr Takshe. She said the enhancement of urban greening and sustainable building practices, strengthening regulations and enforcement to protect vulnerable populations, plus support for research and innovation in climate resilience all help build a climate-resilient future.
