Extreme Events and Hydrological Hazards During the Holocene and Common Era
Session ID#: 248041
Session Description:
Instrumental records of extreme events (e.g., tropical cyclones, floods, droughts, etc.) are spatially and temporally limited, creating significant challenges in understanding natural hazards with long or non-stationary periodicities. Catastrophic events like Hurricanes Katrina (2005) and Helene (2024), Cyclone Chido (2024), the 2024 Spanish floods, Super Typhoon Yagi (2024), and the 2024 Hajj extreme heat disaster highlight the need to contextualize seemingly unprecedented modern extreme hazards with additional observations offered by paleo-records. Long-term perspectives provide critical insight into risk and aid decision-making within vulnerable communities increasingly experiencing hazards in a changing climate. We welcome submissions reconstructing extreme events throughout the Holocene and Common Era. We strongly encourage the submission of studies using high-resolution records, multiproxy techniques, novel proxies, or proxy-model experiments that characterize hazards, understand interactions with the climate system, or develop mitigation strategies that reduce exposure and risk for vulnerable communities.
