Attribution of extreme weather events and their impacts
Conveners: Tamara Happé, Vikki Thompson, Paolo Scussolini, Sjoukje Philip, Sarah Kew, Sanne Muis, Doris Vertegaal

Due to climate change, extreme weather events are becoming more frequent and intense. Extreme weather-related events, such as heatwaves, wildfires, droughts, floods, and hurricanes, can cause impacts to human health, infrastructure, and ecosystems. Besides affecting the climate, human activities have altered other factors that can drive the impacts of these events, such as the land-use, the hydrology and the exposure.

In recent decades, extreme event attribution (EEA) has become more widespread, and extreme weather events are rapidly attributed to climate change through different methods. More recently, EEA has expanded to also attribute impacts, in terms of fatalities, damages, displacements, etc. EEA and impact attribution studies are useful for a variety of different purposes, including raising awareness, litigation, the Loss and Damage Mechanism, decision-making, and adaptation.

In this session we welcome research exploring different methods to attribute weather extremes and their impacts to different drivers, including climate change, land use changes, adaptation, etc. We also welcome contributions investigating the utilization of attribution for societal scopes. This includes but it is not limited to:
• Comparison of different attribution methods;
• Developing a new method for attribution;
• Attribution of extreme events;
• Attribution of impact of extreme events;
• Applications of attribution studies.
