Professor Hannah joins 53 other individuals in the 2023 Class of Fellows. AGU, the world's largest earth and space sciences association, annually recognizes a select number of individuals for its highest honours. Since 1962, the AGU Union Fellows Committee has selected less than 0.1% of members as new Fellows.
Professor Hannah was selected for his “ground-breaking contributions to our understanding of the links between river flow, temperature, ecohydrology and climate”. Fellows are selected each year in recognition of their embodiment of AGU’s vision of a thriving, sustainable, and equitable future powered by discovery, innovation, and action. The AGU also selects fellows who conduct themselves with integrity, respect, and collaboration while creating deep engagement in education, diversity, and outreach.
