Brinepools are one of the most extreme environments on the planet, but despite their high salt content, exotic chemistry, complete lack of oxygen, these pools are full of life and unique in the Earth’s rainfall patterns We provide a record of the Credit:AceanXPlorer
New research reconstructing extreme rainfall in Arabia reveals that the area’s rainfall is five times as extreme as just 400 years ago, highlighting the need for preparation amid increasing urbanization .
Miami University Rosenstiel University Science-led research findings of the ocean, atmosphere and earth suggest that the past two thousand years have been much damp, with the region’s climate being once vegetated with lions, leopards and wolves It’s similar to roaming the Savannah. The harsh modern desert. The study was published on February 21st in the Science Advances Journal.
“As major development projects like Saudi Arabia’s Neom continue to reconstruct the landscape, these findings bring climate resilience and disaster preparation to address the growing threat of extreme weather events in the region. highlights the important needs to strengthen the Department of Marine and Geologic Sciences at the University of Miami Rosenstiel University.
The research team uses a remotely operated vehicle (ROV) deployed from the research vessel, Marine Xplorer, to sediment cores from deep sea salt pools in Aqaba Bay, an extension of the North Red Sea. extracted. The chemistry of brine preserves unobstructed sediment layers and provides a unique and highly accurate record of late Holocene rainfall trends.
They discovered that the last two thousand years in Arabia have been much damper. The area once had vegetation savanna and about 200 years ago, with rainfall twice the current amount.
“This is an important record for filling the history of the Middle Eastern climate. What it tells us is that both the climate, average and extremes, can change dramatically in this region. The assumption of future long-term climate stability is not good development,” said Amy Clement, professor at the Faculty of Atmospheric Sciences at Miami Rosenstiel University.
The Middle East is considered a climate hotspot, with Arabia increasing flash floods from heavy winter rains scattered with severe droughts causing widespread disruption and humanitarian disasters. The fluctuations in rainfall in the late Holocene highlight the need for better flash flooding and drought preparations and future trends in water brightness as the Middle East rapidly urbanizes. The devastating floods across the Arabian Peninsula in the winter of 2024 highlight the urgency to study the frequency and triggers of such extreme weather events.
“Using Oceanxplorer’s technology in conjunction with interdisciplinary experts in marine and climate science, we understand the connections between marine systems and long-term weather and climate trends, and risky regions can prepare for the future. “We can help you to do this,” said Mattie Rodrigue, Science Program Director at Oceanx.
