This paper is a report on the second year of the Touché shared task on argument retrieval held at CLEF 2021. With the goal to provide a collaborative platform for researchers, we organized two tasks: (1) supporting individuals in finding arguments on controversial topics of social importance and (2) supporting individuals with arguments in personal everyday comparison situations. Unlike in the first year, several of the 27 teams participating in the second year managed to submit approaches that improved upon argumentation-agnostic baselines for the two tasks. Most of the teams made use of last year's Touché data for parameter optimization and fine-tuning their best configurations.
