KAUST researchers found a 25-30% increase in winter rainfall in the eastern Arabian Peninsula since 1981, with a 10-20% decrease in the south and northeast. This change correlates with a shifting El Niño pattern in the tropical Pacific Ocean, affecting sea surface temperatures and westerly winds. The study used rainfall data from the University of East Anglia and 39 stations across the peninsula from 1951-2010. Why it matters: Improved understanding of these climate drivers could enhance long-term rainfall predictions, benefiting agriculture and water resource management in this arid region.
A KAUST-led study analyzing over 100 years of satellite data indicates that Red Sea surface temperatures may be cooling rather than rising due to the Atlantic Multidecadal Oscillation (AMO). The research, utilizing KAUST's supercomputer Shaheen II, suggests a cooling phase in the coming decades that could temporarily counter global warming effects. The team collaborated with researchers from the University of Athens and the Hellenic Centre for Marine Research, using data from NOAA, NASA, and the UK Met Office. Why it matters: The finding challenges assumptions about uniform warming trends and highlights the role of natural climate oscillations in modulating regional temperature changes, informing more accurate climate modeling and adaptation strategies for the region.
The Global Water Monitor Consortium, including KAUST, released its 2023 report, finding that 77 of 249 countries experienced record-high temperatures. Saudi Arabia had its third-hottest year but highest precipitation in 20 years. Vegetation vigor in Saudi Arabia was also the highest since 2001, almost 8% higher than the long-term average. Why it matters: The report highlights climate change impacts in Saudi Arabia, emphasizing the need for accessible information on water resources for stakeholders and the potential for increased vegetation due to higher rainfall.
MBZUAI is developing AI-powered applications to help reduce malaria's impact in Indonesia, supported by Sheikh Mohamed bin Zayed Al Nahyan's Reaching the Last Mile initiative. The applications use sensory data fusion to create "digital twins" for precise weather forecasting and real-time environmental representation. AI and clustering analysis identify recurring features contributing to malaria outbreaks, enabling preventative measures and early treatment. Why it matters: This project demonstrates AI's potential in combating climate-sensitive diseases and improving public health in vulnerable regions.
KAUST researchers are studying ancient supervolcanoes, like the Toba eruption 75,000 years ago, to understand current and future climate conditions. Volcanic eruptions serve as natural experiments that push the climate system to its limits, helping scientists understand climate's physical mechanisms. Research shows that volcanic eruptions delayed global warming by about 30% starting from 1850. Why it matters: Understanding the impact of volcanic activity on climate change can improve predictions of future global warming, particularly in regions like the Middle East which are strongly affected by volcanic events.
KAUST marine scientists, led by Dr. Michael Berumen, tracked 47 whale sharks near Al-Lith in the Red Sea using satellite tags. The study, published in PLOS ONE, identifies the area as a significant nursery for the species. The research provides valuable insights into the movement patterns of whale sharks. Why it matters: Understanding these patterns is crucial for effective conservation efforts for this vulnerable species in the Red Sea.
KAUST researchers have developed a passive cooling system that uses solar energy to evaporate water and regenerate salt for reuse, achieving temperatures as low as 3.6 degrees Celsius. The system uses ammonium nitrate (NH4NO3) due to its high solubility and low cost. The crystallized salt stores solar energy and can be reused for cooling when needed. Why it matters: This off-grid design offers a sustainable and inexpensive cooling solution for communities in hot regions with limited electricity access, addressing a critical need exacerbated by climate change.
The Directed Energy Research Center (DERC) received a US$1.5 million grant from the UAE Research Program for Rain Enhancement Science (UAEREP). The grant was awarded at the UAEREP's 5th Cycle Awarding Ceremony in Abu Dhabi. DERC was recognized for its research on laser-induced rain and the development of a mobile high-power pulsed laser using remote sensing. Why it matters: This funding supports the development of sustainable, chemical-free rain enhancement technologies, addressing critical water security challenges in arid regions.
