A KAUST-led study identified 15 large mammal species that inhabited the Arabian Peninsula in the last 10,000 years, tripling previous estimates. Researchers analyzed thousands of petroglyphs from scientific expeditions, publications, and social media. The study identified two species never known to live in the region before: the greater kudu and the Somali wild ass. Why it matters: The findings provide a benchmark for rewilding efforts and inform decisions on which mammals to reintroduce to the region.
KAUST and international collaborators discovered that the Rub’ Al-Khali desert was once a vast lake and river system that supported grasslands and savannahs. The "Green Arabia" period, marked by heavy rainfall, facilitated the growth of a lake covering 1,100 km² with a depth of 42 meters, which overflowed and carved a 150 km valley. The research, published in Communications Earth & Environment, highlights the impact of climate cycles on landscapes and human societies. Why it matters: Understanding the past climate transformations in the Arabian Peninsula is crucial for predicting the consequences of current climate change and its impact on regional habitability.
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.
