 The magnitude and frequency of flooding has been increasing over the past few decades, with some studies suggesting this could be caused by climate change. However, these studies often lack a solid foundation, relying instead on qualitative reasoning or speculation. To address this issue, researchers have developed a hypothesis testing framework for flood trend attribution, consisting of three key elements, evidence of consistency, evidence of inconsistency, and a confidence statement. This framework provides a more robust methodology for determining the cause of observed changes in flood behavior. Additionally, it allows researchers to better understand the potential impacts of climate change on flooding. This article was authored by Y. Hun Deca, J. Delgado, S. Olman, and others.
