Anthropogenic climate change has influenced global river flow seasonality

Biography
Ms Hong Wang, a PhD student at the Southern University of Science and Technology in China, between 2021 and 2025, has shown that human-induced climate change is a primary driver of the weakening river flow seasonality observed across northern high latitudes. Her research reveals significant consequences for both aquatic ecosystems and human societies. Ms Wang also examines how uneven warming along river networks can create thermal barriers that restrict fish movement and disrupt thermal connectivity. These findings provide critical scientific support for risk assessment and climate adaptation planning.
