These images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua satellites show the river on June 19 and August 1, swollen from rains. The area between the White Nile and the Blue Nile to the east is dotted with pools of standing water as well. In the false-color images, water is blue, vegetation is bright green, naturally bare soil and low vegetation are tan and drab green, and clouds are light blue and white. The flooding has displaced 13,000 people, leaving more than 3,000 homeless, and destroying crops.

Among the critical episodes of that decade mentioned in narrative sources are two famines said to have been so severe that they altered the course of the rebellion. These have been little examined heretofore; however, recently improved dating of atmospheric aerosol records derived from polar ice cores and geoscientific studies of the impacts of volcanic eruptions on climatic and social conditions provide a new lens through which the consecutive famines can be understood, supporting the contention that volcanic forcing of the environment was a significant contributory factor for both occurrences. In addition, this fresh perspective enables a reassessment of the textual sources concerning these seminal episodes of Judean history. https://images.squarespace-cdn.com/content/v1/5dc8a65148e09348338d94b3/bcd9b95f-15e3-46ea-92ee-23c912374fcd/peabody-museum-exhibit.jpeg Home - Yale Peabody Museum The Yale Nile Initiative gallery pictured here was installed for the March 2024 grand re-opening of the Yale Peabody Museum after its complete four-year renovation. The YNI exhibit is located prominently in the Central Gallery, a light-filled and welcoming space adjacent to the dinosaur hall and classroom spaces. The double-window display focuses on the research of Yale scientists and historians and their colleagues, and is a particular example of successful interdisciplinary research. The accompanying text is designed to be approachable by a broad audience: the museum has had over 300,000 visitors since its re-opening. https://images.squarespace-cdn.com/content/v1/5dc8a65148e09348338d94b3/1750006256555-V7356QYHCZEDLC94RHQH/peabody-meeting.jpg Home - Yale October Workshop Supported by the 2025 Yale Planetary Solutions Seed Grant courtesy of the Yale Center for Geospatial Solutions, the team is excited to host an in-person workshop in October! The workshop is titled “Resilient Rivers: Historical Lessons for Climate Adaptation and Sustainable Governance”. Physical geography professor Mark Macklin of the University of Lincoln will serve as the keynote speaker. This project builds on the Yale Nile Initiative to explore how ancient riverine societies adapted to extreme climate events. An intensive workshop will bring together historians, climate scientists, and regional experts—including African and Middle Eastern scholars—to extract actionable insights for modern climate resilience strategies. https://images.squarespace-cdn.com/content/v1/5dc8a65148e09348338d94b3/1574445918089-6D1WCTGR3UICXWR86LFM/main_1200.jpg Home - YNI Lecture Series The Yale Nile Initiative Lecture Series brings together some of the world’s leading experts on climate proxies, hydrology, volcanic forcing, climate modeling, ice core geochemistry, and the history of Egyptian and other pre-modern societies. YNI exists in a unique space of environmental humanities and paleoclimatology—building upon and expanding prior research in the fields.

These images from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra and Aqua satellites show the river on June 19 and August 1, swollen from rains. The area between the White Nile and the Blue Nile to the east is dotted with pools of standing water as well. In the false-color images, water is blue, vegetation is bright green, naturally bare soil and low vegetation are tan and drab green, and clouds are light blue and white. The flooding has displaced 13,000 people, leaving more than 3,000 homeless, and destroying crops.
